Also referred to as voice over internet protocol.
The regional it Director stated that these services can all be intermingled in customized workflows to support their development strategies and programming requirements. Cincom also had to transition off of a Public Switched Telephone Network (PSTN) by first integrating it into a VoIP framework; a very challenging task according to the regional it Director. This was essential for creating an effective platform for growth that would also capitalize on the deregulation occurring in the telecommunications market (Cannon, 484, 485). The following section shown a representation of the schematic that is comparable to how Cincom dealt with this challenging issue .
hat as Learned
Just how central VoIP can be in the development of any corporate strategy was made very clear in the examples learned about at Cincom. VoIP is literally the backbone of the entire application development platform of Cincom today. at&T is so tightly intertwined with Cincom today that…… [Read More]
4B in the United States alone (Juan, Pluckebaum, 2010). The adoption of Federated VoIP technologies that alleviate the bottleneck caused by traditional PSTN frameworks are being pioneered by Google with GoogleTalk, in addition to Microsoft with Skype (Nunn, McGuire, Crowe, 2010). Federated VoIP technologies will continue to revolutionize this area of the telecommunications for decades to come, further lowering operating expense (OPEX) levels of spending and eliminating very large sections of Capital Expense (CAPEX) budget constraints (Nunn, McGuire, Crowe, 2010). The reduction in CAPEX initial upfront costs and the continual erosion of OPEX costs for enterprises will ensure a high level of VoIP adoption over the long-term. This adoption will come at the expense of traditional PSTN systems and networks, which will gradually be replaced with enterprise-wide VoIP systems. Additional factors that define the future of VoIP include the proliferating number of mobile network connections combined with 4G speed now…… [Read More]
VoIP Phone Systems:
Beneficial to the Workplace
A Voice over Internet Protocol, or VoIP, system uses groups of transmission technology, communication protocols, and other methodologies in order to allow the delivery of voice communications and multimedia over Internet Protocol networks (International Engineering Consortium, 2007). The major development of mass market VoIP service began in 2004. VoIP is tempting for both the individual and business because it often offers unlimited international and domestic calling services for one flat monthly fee. Businesses are enjoying the benefits of VoIP because of its efficient use of bandwidth and its low costs (International Engineering Consortium, 2007).
Currently, the customer has primary rate interface (PI). PI is a telecommunication standard that carries many voice and data transmissions between a couple of physical locations. PI is not ideal for our customer because its use is intended for large enterprises rather than small business (Unuth, n.d.). The customer…… [Read More]
Bit errors, which may be perceived as InErrors and OutErrors prove most significant. Some manageable systems will not permit one to drill down further into the error state, albeit, some systems allow this action and consequently enhance the troubleshooting process. hen these errors surface, one should initially test the cabling channel connected on that port as well as confirm the installation of the latest revision of software on the system and the updated, current status of the firmware calibration. The tester also needs to ensure interfaces and/or patch cords are relatively new. As each implements a limited number of mating cycles, a specific channel may appear to be malfunction when it is performing correctly (VoIP performance testing fundamentals).
The tester also needs to examine duplex configurations as having full duplex links duplex proves vital to performance. Mismatches and/or channels auto-negotiated to half duplex will further limit VoIP operations. Half duplex…… [Read More]
This system was problematic because of the number of students in the district and the time that it took to engage in this type of communication.
In an effort to find a solution for the problem an Information Systems Manager was called in to assist the district (Milner, 2005). After abandoning an idea that called for the expansion of the traditional telephone system by placing new jacks in classrooms because it would be too costly, the manager advised the use of VoIP for the school system (Milner, 2005). The article explains that throughout the 2002 school year the district implemented the VoIp system throughout all of its 13 schools.
The school district and other school districts throughout the country have benefited greatly form the adaptation of VoIP systems. VoIp offers greater communication between parents and teachers and also serves as an educational tool for students. Overall there has been very…… [Read More]
12). Each would require however separate DHCP servers so that firewall protection could be easily integrated within the system (Kuhn, Walsh & Fries, 2005; Flatland, 2005). H.323 SIP and other VOIP protocols can be disconnected at the voice gateway that interfaces with the PSTN to allow for stronger authentication and access control on the gateway system (Kuhn, Walsh & Fries, 2005). However this can make key management problematic. Other ways to secure the data and voice network include implementing "packet filters" to track malicious connections (although this doesn't always work and is not always sensible) or IPsec and Secure Shell to manage remote voice and data access so hijackers can't utilize the remote system (Kuhn, Walsh & Fries, 2005).
If performance declines because of security measures then the organization can take advantage of encryption at a gateway like the router rather than "individual endpoints" which would allow "IPsec tunneling" however…… [Read More]
Voice over Internet Protocol (VoIP) can be defined as a series of technologies and technique that is used for release of voice communications and multimedia through Internet Protocol networks. In some cases, this technique is referred to as a means of converting analog audio signals into digital data that can be delivered through an Internet Protocol. The use of the technique is attributed to its ability to transform standard Internet connection into a platform for free phone calls. In the past few years, Voice over Internet Protocol has emerged as an innovative technology with the capability of completely transforming phone systems across the globe. As a result, VoIP providers have not only existed for a considerable period of time but are also growing steadily. However, the use of VoIP to rework modern phone systems is characterized by several advantages and disadvantages.

Voice over IP (VoIP) Security
Voice over Internet Protocol or VoIP refers to making use of telephone services over that of the computer networks. During the first part of the process, the VoIP makes an analog signal which is evolved from the speaker's voice. It is then transferred to a digital signal and further transfers over that of an IP network and this is well inclusive of the Internet. Voice over Internet Protocol is also inclusive of any types of software, hardware, or even that of the protocol which could be linked to VoIP. There are very many examples which could be found relating to VoIP technologies which are being widely in use and there are several of these technologies being provided by various companies. Their various systems have the necessity to make use of analog telephone adapters in such a manner so that the standard type of telephones could…… [Read More]
Another option is to use a network simulator which is a device that allows you to exactly model the target network and then see the effect of changing key factors such as routing, link speeds and priorities (Voice-over-IP (VoIP) and network performance, 2007).
The questions that arise after deployment include: is the VoIP system delivering adequate perceived voice quality? And Is the VoIP application affecting the performance of other applications? Voice is, by definition, analogue in nature and voice quality is highly subjective and the same network may deliver different perceived quality for different voice types. When it comes to measuring voice quality, there are two essential advances- analogue and digital. An analogue voice quality tester works by producing a real voice call across a network and weighing it against the received call with the reference call. A digital voice quality tester works by analyzing the packet data stream containing…… [Read More]
Fundamentally, proxy servers get SIP messages and redirect them to the next SIP server in the network. Proxy servers are able to provide operations like authentication, authorization, network access control, routing, reliable request transmission, and security. (ii) edirect server: Gives the client with information regarding the nest hop or hops which the message must take and subsequently the client contacts the next hop server and UAS directly. (iii) egistrar Server: Processes requests taking from UACs for registration of their present location. egistrar servers are frequently are co-situated with a redirect or proxy server.

Functioning of the SIP:
SIP is an easy, ASCII-based protocol that utilizes requests and responses to set up communication among the different components in the network and to finally set up a conference among two of more terminal points. Users in a SIP network are recognized by a unique SIP address.…… [Read More]
Skype is not a new technology. VoIP has been around for years but Skype took years to reach the kind of status it enjoys today. Owing to its pioneering status, Skype became popular rather fast which can be held responsible for its slow growth in later years. While Skype was everything that VoIP was touted to be, it still lacked the kind of culture and corporate strategy needed to turn Skype into a major force. Founded in 2003, it was not until 2009 that Skype realized it's potential. The strategy lacked growth which was one of the most major problems with the company. It was indeed unfortunate that Skype with all its potential and pioneering status was not able to devise a growth strategy.
Most of the people using Skype did it for free. They were more interested in computer to computer calls instead of buying minutes to call friends…… [Read More]
Voice over Internet Protocol, also known as VoIP, converts voice signals into data packets and transmits them over the Internet. VoIP services still stand on the cusp of being included in the list of services to be regulated by the Federal Communications Commission (FCC). As is well-known, the public switched telephone network has been under the scrutiny of the FCC for the latter part of it's existence. This paper will explore if a similar approach can be taken for VOIP, this form of telecommunications through information services, and what the ramifications of such an approach will be. Many contend that VOIP is the future of voice transmission, with potential improvements over voice clarity and reducing costs of transmissions. This is preceded by the traditional method of voice transmission that is through towers that aggregate and distribute signals, and cables and wires that transmit signals. VoIP services over the world have…… [Read More]
With the advent of information technology, the ways different aspects of life work and operate have changed a great deal. The advancement in telecommunication sector have revolutionized and redefined the communication systems at all aspects around the world. The process of bringing the world closer that started with the invention of Morse codes has now entered an era of its own where distances of miles are bridged to a few seconds. This is the world of internet protocol. The invention of the internet and then its integration with the telecommunication system has redefined the meaning of communication and revolutionized the way it is done all together.

Communication Upgrade Plan
Communications Upgrade Plan
The Abco Company wishes to upgrade its telecommunications technology to a system that is more efficient than the outdated Centrex system now in place. As part of the upgrade plan, the CEO has asked for an explanation of the various systems and technologies available for the upgrade. This research explores various technologies and recommends the proper solution for the business problem at hand.
Communications Upgrade Plan
The Centrex phone system has been the standard in business telecommunications since the 1960s. The system has been the only system of this type for many years. usinesses, such as Abco have had their Centrex System for many years. However, aside from being outdated technology, the Centrex System is no longer the most cost effective solution for businesses. The Abco Corporation has had its Centrex system for as long as anyone can remember. Until recently, no one had…… [Read More]
The diffused infrared configuration however, uses a transmitter that fills a given office space with signals. The signal receiver can then be located anywhere in the office area in order to successfully receive the I signal.
The Spread spectrum LANs
This form of arrangement utilizes the multiple-cell configuration. Each of the cells are appropriately assigned a unique center frequency that lies within a specific band in order to avoid signal interference. This transmission technique makes use of two methods; frequency hopping as well as direct sequence modulation
The Frequency hopping method uses signals that jumps from a given frequency to the other within a specific bandwidth. The transmission unit then "listens" to a give channel and if successfully detects any idle time (a time when no signal is transmitted),then transmits the packet via the full channel bandwidth .In case a channel is deemed "full," the transmitter then "hops" to the…… [Read More]
" The problem with these primitive models is that they are still mainly oriented on data retrieval rather than optimal voice transmission.
However, research is well on the way and it seems that it will be less than a year before we can talk about Voice over WiFi or VoWiFi. On the other hand, it is obvious that there are several problems that the VoWiFi providers will have to deal with before the models are commercialized on the market.
First of all, there is the issue of security, something I have also referred to when discussing Voice over IP. The problem does not actually refer to security itself, but to the fact that voice transmission may be affected by the security protocols installed to protect the data exchange. In many ways, this is similar to what we are experiencing nowadays when we have a firewall installed. The problem with voice…… [Read More]
Routers, LANs, MANs, and VLANs
Routers have long been an important component in a network beginning with the transmission of data traffic. ith VoIP on its way it will also evolve to support voice traffic as well. It does so today in a lab and test environment as well as limited VoIP deployment.
hat security functions does a router provide and are these functions adequate for securing the LAN or MAN?
Internet Voice, also known as Voice over Internet Protocol (VoIP), is a technology that allows a caller to make telephone calls using a broadband Internet connection instead of a regular (or analog) phone line. Some services using VoIP only allow a caller to reach other people using the same service. Other services allow calls to anyone with a telephone number, including local, long distance, mobile, and international numbers. Some services only work over a computer or a special VoIP…… [Read More]
AOL, for example, drew users away from DSL with its broadband services, simply because it was easier to add broadband to one's existing AOL account than to go through a new service. Thus, through using Shaw rather than Skype, a user could consolidate his or her computer services. So, Shaw could thus make use of its current marketing position as a more tried and true organization in contrast to the upstart Skype.
Shaw could thus create a new, combined product service of VOIP and other Internet services to compete with Skype, although it might have to consider offering this service free for a time to lure customers in, as a promotional device. Shaw could even make more efficient use of placing than Skype by specifically emphasizing its Canadian/North America location, to corner that area of the VOIP market, stressing the greater and more personalized services it could offer North American…… [Read More]
Comcast feels that the product life cycle is still in its infancy or introductory phase, and that costs will plummet once the technology improves, and more consumers use the product and make it integral to their lifestyle. Vontage like all of the companies has the advantage of the lack of federal communications regulations regarding the technology, but these laws may change in the future -- thus for all companies, the product is still in its growing phase, as branding, positioning, quality and also federal regulations are still an issue, but things are not competitive enough for companies to have a market-wide price war, as sometimes occurs during the growth phase of the product life cycle.
Bundling is advantageous to a company, because it yields a captive consumer audience. A company can lure in a consumer with a low price, but once the consumer subscribes to the bundle, the company…… [Read More]
Secondly, Shaw needs to broaden its national base. Shaw is currently a Canadian-based communication company, while Skype serves eleven million users in the international sphere. It is in Shaw's interests to expand its outreach to other, preferably internationally-based communications companies, regarding VOIP technology, to ensure that it can make inroads into the VOIP market.
Thus, Shaw's deployment must be an increase in advertising and services to its existing Canadian consumers. The second leg of the marketing strategy will require legal and economic negotiations with other firms to establish joint agreements with Shaw in other nations and continents. This second aspect must be accomplished not only to limit Skype's expansion and potential to enter into new agreements, but also to circumvent other communication market second-moves from doing the same, such as Verizon.… [Read More]
features of telecommunications networks, including key networking technologies. Cover the Open Systems Interconnection (OSI) model, including each logical layer.
The OSI layer covers the different layers and types of communication that occurs within a network. The layers, in order of complexity from greatest to lowest are application, presentation, session, transport, network, data link and physical. The physical layer is the actual transport medium like network cable and such while routers and switches address much of the middle layers while the "window" to the user is the application layer at the very top. Telecommoniciation networks, and this is something that will be answered more in-depth later in this report, are very computer driven and are in many ways indistinguishable from regular computer networks as phone and conventional internet networks are very much one and the same and this is especially true when speaking Voice over IP (VOIP) technologies and the like.…… [Read More]
If Shaw decides to enter the VOIP market it must find a way to overcome Skype's first mover advantage. It could do this in terms of market placement in the sense that it can offer VOIP as a part of a bundle of other Internet services to its current Canadian clientele. This would certainly be an incentive to Shaw's current Canadian Internet users, but might not draw new users from a broader, international base. However, Shaw can also offer security of its longstanding reputation in other communications services. As in a company is better established than Skype, and thus may weather a potential market shift or change. Shaw can also assure its customers that it will provide continued assistance and support, should their be any difficulties in using or integrating the new VOIP communications system into current business or personal systems. Shaw must corner the emerging VOIP market on ease,…… [Read More]
Cyberspace as the Most Dominant Domain
Cyberspace is the indefinite place where all online communications take place. It can also be defined in computer networks as the electronic medium. The name was coined by William Gibson a science fiction author. When he coined the name, he was looking for a word to describe the global computer network he was envisioning. The U.S. government defines cyberspace as the country's control system composed of interconnected computers, routers, servers, switches and fiber optic cables Adams, 1997.
It states that cyberspace is the nervous system for the military. The use of electromagnetic spectrum and electromagnetic to modify, store, and exchange information using physical infrastructures and networked information systems can also be used to refer to the cyberspace domain.
The use of cyberspace to attack others is referred to as cyber terrorism. The attacks occur in form of viruses, which are meant to disrupt…… [Read More]
Electronic communication has become one of the most important methods for people to communicate with one another in recent years. Spielberg (1999) noted that patients have sought to utilize electronic communication with their physicians. In the past, he argued, a variety of exchanges were utilized, including in-person visits, telephone, pagers and voicemail, so it was only natural that communication between patients and those within the medical profession would be extended to the realm of electronic communication. Thus, the market has driven the need for health care organizations to begin to explore how they can use electronic communication methods such as email, the Internet, online chats or even SMS messaging to bridge the communication gap with their patients. hile the market may demand new methods of communication be developed, there are risks inherent to the medical profession that present challenges or obstacles to facilitating the market-demanded electronic communication methods.

HSPA+ is expected to be commercially available in 2008 through [the introduction] of incremental investments and backward and forward compatible handsets. HSPA+ doubles the data capacity and increases voice capacity by three times enabling operators to offer mobile broadband at even lower cost" (elease 7 HSPA+, 2007, p. 3). Likewise, Housami (2008) reports that, "HSPA+ is a manifestation of the evolved HSPA philosophy where the existing HSPA implementation is pushed to its limits by introducing various improvements to increase the efficiency of the system while maintaining backward compatibility" (p. 2).
The term "HSPA+" is the name assigned to the set of HSPA enhancements that are defined in 3 GPP elease 7 (7) and later; the enhanced downlink (HSDPA) was defined in 3 GPP 5 and provides three times the data capacity of WCDMA 99 (using a rake receiver and a single UE receive antenna) (elease 7 HSPA+).

Secured real time protocol (STP) is also being identified to enhance the security parameter of WAN and LAN network elements. "STP provides protection with encryption keys for wired and wireless networks including bandwidth limited channels." (Guillen and Chacon 2009 P. 690). There is also a growing use of IP secure to protect organization from the interception of data over the LAN and WAN environment.
To enhance network security, Chen, Horng, & Yang (2008) postulate the use of public key cryptography. While there is a growing use of public key cryptography, there is still a shortcoming identified with the use of public key cryptography in the LAN and WAN environment. Since the public key is being kept in a public file, it is possible for an active intruder to forge the contents of the public key and use it to get access onto the data kept within the network system.

Cox had no obligation to contribute VoIP derived revenues to the Universal Service Fund, however the Cox management decided to contribute voluntarily. This way Cox has tried to enhance and build its stature as both a good corporate citizen and established carrier.
Although VoIP was in line; Cox didn't breakout its variable and fixed expenses for residential telephony.
Cox had proven its ability to profitably provide first rate telephone service. In doing so, they have experienced that bundled offerings could significantly reduce churn.
There is no to launch the operations of VoIP speedily. By doing so Cox can lock in customers, otherwise Cox would be exposed to competition and rivalry from DBS and other ILECs who are steadily and gradually building the art and science of bundling. Cox should better plan its ploicy such that it can cater for the supremacy of the competitors.

The market was not ready for wireless even five years ago, but that has definitely changed. When Levi's launched its latest 501s marketing campaign earlier this year, a wireless site was a central part of its digital strategy. Now there are nearly 30,000 public wireless "hot spots" in the United States. Advertisers believe that now that wireless has finally become a medium with which consumers are comfortable, the next stage is its exploitation by brands. Many feel that the wireless sites will increasingly become a part of marketing campaigns.
The semi-technical arena is seeing the rise of numerous new search engines, especially since ones such as Google have become so successful.

). Such security should also preplan strategic responses to attacks associated with the network (Dawkins et al.).
A book entitled "Surviving Security: How to Integrate People, Process, and Technology" explains that the rapid expansion networking and networking technologies necessitates greater security needs. The author asserts that parts of the network such as routers, switches and even network printers are vulnerable (Andress). The article further explains that the router or switch contained between the firewall and the internet access or between the firewall and the internal network are often vulnerable. Organizations with networks should work hard to secure them at these points. The article also states that if attackers can gain access to a network at these points, they can gain access to sensitive information and compromise the stability of the network. Also attackers who gain access to a network at one of the aforementioned points will also be able to…… [Read More]
Microsoft purchased Skype for $8.5 billion (Primack, 2010). This marked the third time in five years that Skype had been sold, first to eBay and then to a private investment group. The company filed for an IPO, but that never came to pass as Microsoft entered the bidding and took over. There have been significant questions from industry observers about the value of Skype to Microsoft, and whether Microsoft overpaid for Skype. Analysts have attempted to determine what Microsoft's plans for Skype are, and whether those plans justify the seemingly high valuation (Bright, 2011). Since the purchase, there have been a number of changes at Skype that have seen Microsoft seek to capture value from the company. One recent change, for example, is the pending launch of conversation ads (McCue, 2012). To better understand this acquisition, the business of Skype and the needs of Microsoft must both be taken into…… [Read More]
new technologies have given birth to data analysis from the IT backrooms, and have increased the possibilities of utilizing the use of data-driven results into every aspect of an organization. However, much as improvements in hardware and software have made the advent of big data usage possible, the only consideration is not technology. It is important for organizations to take very holistic approaches to integrate big data into every aspect of their business procedures, their daily operations, and strategies. Big data brings both challenges and opportunities to every business. To be able to obtain value for big data, it is important to carry out timely analysis of the data, and the result must be such that can influence important business decisions and bring about positive changes. Having the appropriate combination of people, technology, and processes determine the overall effectiveness. Key processes, roles, and functions are optimized by analytics. It can…… [Read More]
Skype competes as a differentiated player in the VoIP industry. The company's business model is based on free distribution of its software, and then encouraging users to sign up for a payment plan that covers usage. The company's technology was once innovative but has now been commoditized (Blodget, 2011). The company was recently purchased by Microsoft for $8.5 billion (Saporito, 2011). The value of the company derives not from the software but from the company's 170 million-strong user base.
The company's strategy therefore relies heavily on throughputs. The most important input for Skype is the technology, which is now common. The technology allows users to interact with each other, using text messaging, voice or video calls. The company charges for this service, but still loses money. The main input for Microsoft is the user base. ithout the massive user base, Skype has little intrinsic value and little means of generating…… [Read More]

Microsoft purchased Skype for $8.5 billion, and immediately critics of the deal questioned the value that Skype could bring to Microsoft (Bright, 2011). Skype was plagued with old technology that it did not even develop itself (Ricknas, 2008; Kharif, 2009). The company's 2009 SEC filing revealed that its financial condition was terrible. hile the company has been rapidly increasing its user base, less than 10% of users are paying customers and the rate at which paying customers are growing is slower than the rate at which customers in general are growing. There are two feedback loops that are critical to Skype, one of which is negative and one of which is positive. These feedback loops can be identified through the analysis of the company's business and financial statements.
Making a Case
The key balancing feedback loop at Skype is that which keeps the company unprofitable, and this…… [Read More]
These include lack of emergency calling, call security, and sound quality. Because VoiP providers, including Skype, are a bypass to the conventional phone system, they do not typically provide emergency calling services (Schueneman, no date). Thus, the firm will have a more difficult time accessing police or fire services. It must be considered how often such services are needed by the office.
The second consideration is with respect to call security. Skype's security is proprietary and a closely guarded secret (the Economist, 2008). Thus, the level of call security on Skype is unknown. For a legal firm, the potential outcomes in the event of a breach in call security can be catastrophic. Cases could be lost, sensitive information could be revealed and the firm's reputation could be damaged (Nugent, 2007).
The final consideration is with respect to sound quality. Skype and other VoiP software are often of substandard sound quality.…… [Read More]

To avoid repeating negative historical experiences, regulatory regimes need to block the control and domination by networks/platforms. In the report, "Infrastructure and Development: A Critical Appraisal of the Macro Level Literature," Stephane Straub (2007) reported that at times, in some developing companies, "the hope of getting a fixed-line installed is a distant and costly dream" (p. 4). Meantime, the primary option for the individuals waiting for fixed-line telecommunications services would likely be having to us a much too expensive cell phone.
In 2010, much of the fixed-line telecom industry faces growing threats from cable and wireless service competitors.
As the writer of the quote introducing the study section pointed out, more firms are realizing "a cellular wireless solution" generally provides "more stability than the usual wired connections… [and serves as] a valuable asset built for the long haul" ("Lincolnshire Drainage Board…," 2010, ¶ 9).

First, the decreasing subscription of land-line telephone service due to the proliferation of cellular technology. Since 2001, there has been a steady decline in market share of land-line telephones as more and more users chose to use cell phones as their permanent phone provider. WorldCom, with its specific focus still on land-line services has created a multitiered strategy to promote land-line use. They emphasize new packages that are more affordable than older packages, with shorter time commitments, as well as more land-line services than previous offers. WorldCom believes that this strategy promotes greater diversification of land-line services across many different platforms that will increase the overall usage and service provision for American consumers. The second major issue that impacts WorldCom's future strategic vision is the emergence of VIP services as a mode of land-line phone services.

For instance, the existing research does not reveal conversational abilities, level of comprehension or whether or not the learner is able to read and write English proficiently. All of these issues are relevant to understanding the success of teaching ESL online. A better understanding of the failure and/or success rates of online learning when compared to traditional teaching methods is needed so that instructors and administrators know whether or not they want to utilize online learning as a curriculum tool.
For the purposes of carrying out this type of research, the researcher must seek out institutions of learning that currently use online language learning to teach English as a second language. A decision must be made concerning whether or not the research will focus on adult learners or young learners. Once this decision is made,…… [Read More]
4). The strength associated with this approach is ensuring that an organization has access to its mission-critical data in the event of a disaster, with the concomitant weakness being the relatively modest costs involved.
The next step in developing the organization's information system recover plan is to take stock of existing hardware. As Cohen emphasizes, "If you have been hosting your company's Web site on an office computer, it is time to stop. For the cost of a cup of coffee per day, a Web-hosting center can fully protect your site off-site, where it will not tie up your company's bandwidth" (p. 3). This approach to maintaining important contacts with customers and an organization's intranet has several strengths over an organization's hosting the Web site in-house. For instance, eagan (2006) notes that, "A hosted solution provides an organization with the flexibility of deploying an IP-enabled system without the maintenance costs…… [Read More]
FDDI's emergence as a networking interface standard is assured given its adoption across both Token ing and TCP/IP-based networks and heterogeneous LANs that rely in large part on Fiber Optic cabling to ensure the highest level of performance possible.
Fiber optic cablings' unique set of advantages makes this specific type of connectivity solution ideal for high bandwidth requirements of LANs and WANs that transmit voice and data as the majority of their traffic. It departments that choose to implement Fiber Optics as their backbone cabling standard often include a series of repeaters to ensure the signals sent are strengthened before they reach their destination system. The development of cabling techniques for allowing for synchronous communication is also significantly changing how fiber optic cabling is used.
The role of fiber optic cabling in the creation of networks is clearly seen in the context of the OSI Model. The Data Link…… [Read More]
The fact that they are interconnected and promoted together is an indication that there is strong managerial relationship between both firms. ("Transform the way your usiness Works," 2011)
At the same time, Skype and Verizon have a similar kind of relationship. This is because both companies have a shared interest, with Skype being offered on Verizon's phones. While Verizon, is able to attract Skype's large customer base. Since they are working together, this is a sign that the management of the two organizations has a strong relationship with each other. (ernier, 2011)
What kind of negotiations has Skype engaged in to enter the North American market? How does culture play a role?
The kind of negotiations that Skype has utilized is to partner up with as many firms as possible. The reason why, is because if they can begin offering their service as an application on various networks. Then, they…… [Read More]
The truth that electronics aid humanity may be a subject for debate. However, it must be noted that nothing else may beat your doubt on electronics but the fact that we can derive from others' experiences that the technological advances in electronics really assist man in sustaining his life and surviving from the weaknesses of our physical body. More so, we may derive such information from our relatives and friends who may have experienced recovering from diseases with the aid of advanced biomedic machines. or, you can also ask this question to yourself to provide a view on how effective do you really believe can technology that is applied in electronics help, assist, and aid humanity -- "Would you rather go for the old method and practices of medicine than how medicine is practice these days?"

Web conferencing, though it is a very effective tool has its own drawback. The lack of human element and the absence of nonverbal feedback, particularly when dealing with clients constitute the negative side of electronic communication.
The field of medicine is one that uses web conferencing to great success. Telemedicine success stories are a good indication of the useful application of web conferencing. Web Conferencing, for example allows physician assistants and nurses to consult physicians and experts pertaining to patients symptoms and start appropriate treatment method for patients in hospitals and health care units running in remote locations. Similarly educational institutions embrace the technology offering e-learning modules for students from geographically diverse areas.

6: Existing Cable and Wireless Design
The company will establish wireless access using the LWAP (lightweight access point). The LWAP will be distributed to all the facilities through the WLS. Typically, WLS will be installed to assist in providing the traffic tunnel and failover authentication. To enhance the security of the WLAN, the company will install the encryption system at the wireless access point, the encryption protocols will contain WPA/WPA2, and there will be an AES encryption at all the wireless access point using the 802.1 X authentication.
The company will redesign the local backbone infrastructure in order to increase the network bandwidth. There would be 100 BASE-T4 cabling to the 7 Cisco 2613 routers. The cabling system will assist the company to achieve efficient network connectivity for future growth. The 100 BASE-FX (fiber) cabling will be attached to the Cisco 7507 routers, which will assist in achieving more expansion…… [Read More]
In 2010, Microsoft purchased Skype for $8.5 billion, and at the time many observers were unsure of what value Skype had for the software giant (Bright, 2011). According to some, Skype's core VoIP business is subject to commoditization (Ricknas, 2008). Another issue that Microsoft must address is Skype's business model. Prior to the purchase, Skype had filed for an IPO and the filing documents reveal some major financial issues for the company. hile it states that part of its strategy is to attract more users of both free and paid products, its income statement indicates that the users of free services are not making enough paid contributions to cover the cost of servicing them. Although the Skype user base was growing year-over-year, the company's profitability was declining. The company lost $1.4 billion on revue of $381 million in FY2007, turned a small profit in FY2008 and then proceeded…… [Read More]
Niklas Zennstrom and Janus Friis formed Skype in 2003. The two produced VoIP software based on P2P architecture that revolutionized the field of communication. The software provided its users with high quality and free voice calls, as firewalls did not affect this software. The company rapidly grew due to the free quality voice calls reaching its critical user mass in a short time. The company later started premium Skype products to corporate users, which increased the revenue generated. VoIP technology used by Skype means that the company relies on the internet or IP-based networks to transmit the signal. The information transferred through the software requires protection from hackers and for privacy thus encrypted.
Microsoft acquired the company in 2011 for a record 8.5 billion U.S. dollars. This is considers one of Microsoft's most expensive acquisitions as the company grows to become the number one software company in the…… [Read More]
Web conferencing systems have been faced with resistance to change by those responsible for knowledge transfer and knowledge management, as these systems are seen as a threat to the more costly and time-consuming approaches to sharing knowledge. It has been seen that employees will resist using Web Ex-systems as they are afraid it makes the transfer of their knowledge too easy, and therefore is a risk to their status in the organization (Hu, Hafsi, 2010). Studies of change management indicate that when the Chief Executive Officer (CEO) or comparable leader within a business supports and provides pragmatic, honest feedback about how the Web conferencing system will be used, resistance is minimized and broader adoption occurs.
The rapid growth of Web conferencing systems has been accelerated by the growing reliance on more advanced security technologies and features in these platforms (Pearce, 2009). In conjunction with this development has been the…… [Read More]
The pilot was initiated six weeks before implementation in order to ensure that no problems occurred when the whole system was implemented. The pilot program was also used to provide information and training in the use of the new system. The training entails that users were able to interact with the features of the new system in order to become familiar with them. In this way, users learned to use the new system in a safe environment. This provided them with a platform of learning, where such learning took place with as little as possible apprehension.
In general, the pilot program went reasonably well, although some people had considerable trouble understanding telephones that were operated via computers. Others were afraid that the system would crash while being used. Another factor causing fear was the fact that some users felt they would be monitored in a "Big Brother" fashion. The major…… [Read More]
The surveys should become an ongoing activity as customer behavior and preferences change quite often and the company needs to be aware of all changes to be able to adapt to them. For this, the company needs to have set up a system to send as many surveys online as possible to keep costs under control. Every customer should be asked to provide an email address, which can later be used for sending promotional messages, if the customer agrees to receive communications from Kerry Co. otential systems that meet these requirements are Zoomerang and Inquisite that have quite a large capacity of sending surveys for this kind of business. E-mail surveys are likely to be more appropriate for the young buyers, whereas the elder ones should be inquired about their satisfaction via phone or post, which is a more expensive method. Nevertheless, elders are likely to have a…… [Read More]
Product Returns is a third process area that Imperial Tobacco has to contend with, specifically from its distributors and channel partners. Typically Tobacco products are returned if a specific lot of tobacco or packaging has been found to be defective. There have at times been product recalls as defined by governments. A third reason for product returns is when a product has been discontinued and Imperial is not willing to pay price protection to cover the distribution partners' inventory carrying costs until they are sold. The Product Returns process begins with the issuance of a Return Material Authorization (RMA) that specifically states how much of a given product is being returned and for what reason.
The RMA is then sent to the distributor who then ships back the tobacco products to Imperial. Once the products have arrived back at the company, if they are defective, they are sent to Quality…… [Read More]
An article from last year points to the continuing thrust forward with respect to the integration of technologies and sensory desires for the user, describing the inception of visual aspects into the protocol.
The 2007 article by Ding et al. is focused on the discourse, research and user-end needs which figured into the gradual integration of visual images indicating users status and allowing for the presentation of messaging. Based particularly upon the findings produced by a long-term observation of the patterns of usage for VOIP users, the study would produce a set of conclusions concerning the fashions of usage which have produced the integration of visualization into an already integrative protocol.
The article contends to "shed light on the factors that drive the use of visual enhancements to audio conferencing." (Ding et al., 1019) Among them, the article concludes that there is an impulse when using computer interface systems to…… [Read More]
Sixth, there are tangible cost reductions possible by using Software-as-a-Service (SaaS) applications rented over the Internet vs. buying customer relationship management systems and installing them in a company. Significant and tangible cost reductions are possible using Salesforce.com for example over purchasing Oracle Corporations' CRM Suite, or using manually-based systems based on Microsoft Excel or Word.
Seventh, tangible cost reductions are possible by using project management software to manage the many dependencies and deadlines in a project vs. simply tracking all activities in a spreadsheet. Project management software is specifically designed to track deadlines and the resources needed to attain them, and can also load balance resources to attain multiple and often conflicting goals. It greatly reduces tangible costs of both the project and greatly minimizes the risk of a missed deadline as well in this area.
Another tangible area of cost reduction for it is in the managing inventories in…… [Read More]

On the other hand, applicable laws do have authority and under the concept of moral relativism, it may be justified that any duly passed law be complied with (Svensson & Wood, 2008).
One lesson from this case might be that laws between entities in different sovereign nations can be much harder to enforce than laws between entities within the same nation. In the future, Pakistan and other nations might want to make sure that their contractual agreements contain mechanisms that make them enforceable across international borders. On a broader level, another lesson might be that ill-gotten gains should not be promoted by governments in the first place. Those who believe in the supremacy of divine law might consider the position in which Pakistan found herself to be an example of God's reminding us of the obligation to conduct ourselves ethically toward our fellow man.

Clearly, he companies engaged in this practice were operating with direct intention, and a roper governance system would have made this obvious and prevented it.
In another telecommunications case, a company was found to have included spyware in a company-sponsored "software upgrade" to users' cell phones, that enabled the company to collect confidential information from users' phones without their consent (Khaleej Times, 2009). Not only is this practice clearly unethical, but it is also illegal despite a lack of stringency in the detection of such crimes and the prosecution of large-scale corporate offenders such as telecommunications companies. Again, greater transparency and internal control would have allowed this practice to be discovered much sooner, and the risk of discovery almost certainly would have prevented this action from ever occurring. Corporate governance works best when it is so strong it is only rarely and usually accidentally tested; when purposeful actions…… [Read More]
Web Conference Memo
Web Conference program research
I refer to the work you assigned me, to research on the best web conference program which can help you hold a weekly status meeting. I did research through the internet regarding the same. Through my research, I looked into four various kind of web conference programs namely, OnWebinar, Vyew, OpenMeeting and DimDim. However, to come up with one program, I analyzed each in consideration with the Operating System installed in our computers and other various factors.
Therefore, I would like to recommend Vyew as the best web conference program, because of its features which have listed below:
It's a browser-based web conference program and it operates effectively on Windows, Mac and Linux as well.
It has hundreds of active/archived meeting per user, which means it can support a number of users at a time.
It's very flexible compared to other…… [Read More]
