Computer Network for Bistro Bookstore

Computer Network Planning for Bistro Bookstore

Launching a new bistro and bookstore is going to require three specific tasks be completed to ensure the stability, security and continued reliability of the network which over time will become the backbone of the information system and infrastructure of the store. These three tasks include the development of the new network, defining and implementing best practices and procedures for ensuring security of the network and its contents from unauthorized access, and the definition and use of guidelines and strategies for managing the integration of technological and sociotechnical frameworks. Each of these three strategic areas of the Bistro Bookstore is analyzed in this paper.

Planning the Structure of the Network

As the Bistro Bookstore will have two businesses running concurrently, it will be critically important to have a very agile, secure and scalability network architecture. A star topology will…… [Read More]

Computer Network Security Issues Computer

In some instances, policies implemented mainly as cost-effective shortcuts to network system security have cost otherwise good employees their jobs for violations of excessively restrictive network use policies. In the realm of the home computer user, it is possible to buy many new redundant or unnecessary security programs and features. Generally, appropriate network security should not interfere noticeably with either personal home computer use or computer system use in the workplace (Larsen, 2007).

Conclusion

Computer systems and networks are potentially vulnerable to malicious intrusion attempts that can be extremely harmful to home computer users and damaging to professional organizations. The most common types of attempted system infiltrations are those that exploit long-known software vulnerabilities for which security fixes already existed long before those intrusions. It is possible to substantially mitigate the risks posed to computer and network systems by malicious entities trough simply implementing and adhering to basic system security…… [Read More]

Computer Network Security -- Information

Discussion Question 2 - Security Awareness Training and IA Training

In general, security awareness training consists of periodic classes and online tutorials and related quizzes that promote understanding of the nature of different types of threats to information security (Boyce, 2008; Kizza, 2009). That training addresses threats in the nature of malicious intrusion from external entities, malicious intrusion and misuse of information access or system credentials from the inside; and malicious intrusion attempts to gain access to systems and information through social engineering methods (Boyce, 2008; Kizza, 2009). In our organization, the ISO schedules IT security training sessions for the entire staff and also establishes security certification schedules that require all employees to complete and pass online tutorials by specific dates.

In the article "They've heard them all," two of the most humorous stories detailing naive users' confusion about computers revolve around simple misunderstandings of vocabulary (Mears & Dubie 2006:1). Some people do not clearly understand what 'cookies' are on their computers -- and even if most users today are cognizant of the fact that cookies in IT parlance means something different than chocolate chip vs. peanut butter, they may merely know that cookies are 'bad' without understanding how websites use them to track or store user information.

Networking

The advent of the Internet, wireless and satellite communication and both computing hardware and software improvements continue to make our world a very small place. Ever since these combined methodologies have allowed us to integrate single or 'dumb' computer terminals that once only accepted data from large mainframes, computer networking has become an integral part of our everyday professional and personal lives. Even the most basic networking infrastructure today can contain an extremely large number of individual nodes that are far more powerful than even the most dominant mainframe of just a few decades ago. This new found networking muscle provides anyone and everyone access to an infinite and global spectrum of information in seconds.

Remote Access Computer Networks the

Instead of training sessions requiring trainers and trainees to be together in the same office, trainers can conduct sessions from one location for employees in multiple remote locations without requiring coordinated travel necessary for traditional professional training sessions (Huang & Frahim, 2008 pp90-91).

The ising Importance of emote Access Computer Networks in Business

Naturally, one of the advantages of using remote computer access networks for presentations, conferences, and staff training is the tremendous cost savings of reducing the travel that was necessary for traditional formats of those essential business functions. The modern era of business globalization only increases the value of that aspect of remote computer access networks, by virtue of the corresponding greater need for business travel and the necessary establishment of business operations in different national and international regions. Similarly, the rising focus on green concerns has increased the importance of reducing unnecessary business travel in connection with…… [Read More]

DDOS Attacks Computers Computer Networks

Internet-based DOS attacks can more easily be distributed, meaning there can be multiple machines (often hundreds or thousands, some of them "enslaved" through viruses) sending communications to a particular website -- or technically, to the server on which the site is stored -- that simply overload the server's capacity and could cause it to crash or simply to provide communications that are too slow to be intelligible (oebuck, 2005; Cross, 2008; aghavan & Dawson, 2011). The possibilities and the distance involved make Internet DOS attacks more complex, but with the proper know-how they can be easier to achieve consistently for attackers (oebuck, 2005).

Preventing DOS attacks can be all but impossible, especially in an Internet setting, but taking steps to ensure that a website/server can easily recover from a DOS attack and restore reliable service to users can help reduce the likelihood of that being targeted -- if the attack…… [Read More]

Network Management and Systems Administration

Network Management and System Administration

The aim of the paper is to establish the difference between a system administrator and a network administrator. The paper is thus divided into three sections. The first section deals with the basic definition and responsibilities of a system administrator; the second does the same for a network administrator and the third compares their responsibilities to clearly identify the differences between the two.

System Administrator

The maintenance of computer systems in a company is the sole responsibility of a system administrator. They are responsible for maintaining, upgrading and installing servers. They are also entrusted with the task of checking the security of the server and maintaining its backup as well. They are also involved in programming for automating tasks at the server. For this purpose, they write programs, also known as scripting (Schneider, 2012a).

The emergence of cloud computing as a disruptive innovation is redefining the economics of information technologies, application delivery and the pace of new feature development and introduction. Companies who are standardizing on cloud computing for critical tasks including Customer elationship Management (CM) do so after evaluating several factors, including the opportunity to expense the costs vs. pay for them via capital expense, the customization of the applications, and the ability to selectively update them over time (Lashar, 2009). Cloud-based applications delivered over Software-as-a-Service (SaaS) platforms are paid for as an operating expense, which is often referred to as OPEX. Traditional enterprise software is paid for through CAPEX, or capital expense investment.

Network Vulnerabilities and Controls

Network Vulnerabilities and Controls

Computer networks are constantly under threat from many different sources of attacks. In order to get a clear understanding of the different views on computer security and its characteristics, it is important to define a network. This term means a group of computers that have been interconnected to communicate to one another using electrical signals. The network can be either wired or wireless and the most common of them nowadays is the wireless computer network. The internet or wide area network can link very many computers that are widely and geographically apart.

Computers are therefore linked to communicate with one another via the internet. However, these same computers are prone to attacks from all different angles. Any unauthorized access to ones computer can be defined as an attack since in the process, valuable information may be retrieved from the computer or even deleted. The information may…… [Read More]

Network Standards

Network Standards

A Brief Look Since 1995

This is a research paper that focuses on network standards and protocols that involve strategies in management. Leadership strategies cannot handle the need for network standards to handle billions of users and user generated applications. Therefore management strategies are more appropriate. Furthermore the history of network standards shows layering through the OSI models follows a management approach vs. A leadership approach.

In the OSI model, there are seven layers. The seven layers then acts as a means of managing problems within that layer as it is separated and contained. People can run communication through these layers much more easily and smoothly than through a singular, whole layer. The several layers are more efficient and can handle and spot problems and inefficiencies more quickly. It serves as the basis for network standards.

The history behind network standards provides valuable insight into how organizations emerged…… [Read More]

Network Password Policies and Authorization

All network authorized personnel must be instructed to use "strong" passwords consisting of at least 8 characters; they must include at least one upper and one lower case letter, at least one Arabic number, and at least one "special character" in addition to avoiding any form or abbreviation of the user's first or last name (Boyce, 2002; Kizza, 2005).

Network administrators must also implement applications capable of ensuring compliance by automatically rejecting improper password choices. Additionally, administrators must require authorized users to change their passwords at specific intervals. Finally, office managers must monitor compliance with common-sense rules about behavioral aspects of password security, such as prohibiting divulging passwords to co-workers, requiring users to log off if they leave their terminals, and by providing training into recognizing attempted social engineering to obtain secure information through deception (Larson, 2007).

Likewise, authentication layers can also significantly enhance network security. In that regard, the…… [Read More]

). 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]

Network Security: Past, Present and Future

The work of Curtin (2007) states that a network is defined as "any set of interlinking lines resembling a net, a network of roads -- an interconnected system, a network of alliances." Quite simply a computer network is a system of computers that are interconnected. There are seven layers of communication types identified by the International Standards Organization (ISO) Open Systems Interconnect (OSI) eference Model as well as the interfaces among them. Each layer is stated to be dependent on the services that the layer above it provides including the physical network hardware.

Network Congestion Occurs When There

Attempts to alleviate or at least reduce network congestion including using un length Encoding (LL) for packet size reduction, the use of abbreviated headers for optimizing their path through networks, and the development of protocols that seek to optimize path selection through a network (Wen, Wang, Yang, 2007). The challenge of continually enhancing and increasing network performance through better optimization of paths throughout a network is being made more challenging with the en masse adoption of WiFi as well (Wen, Wang, Yang, 2007).

Computer-Based Learning

Computers are tools for learning; and as such are not essentially different from the way dictionaries, calculators, and videos are teaching and learning tools. However, computers provide a wide range of learning experiences that do make them qualitatively and quantitatively different from other learning tools. Three ways that computers measurably benefit the learning experience include communication, information access and retrieval, and training. Computers facilitate communication between learner and teacher, or between learner and peers. With computers and their applications, the raw data of learning -- that is, information -- becomes accessible to both teacher and learners. Training manuals and tutorials can be digitalized in ways that are accessible to learners regardless of geography and time. In spite of these three benefits of computers as learning tools, there are three detriments to the use of information technology in the higher education classroom. One detriment is the digital divide, or income disparity…… [Read More]

Network Design

The process of gathering technical requirements for a network design project may differ from one organization to another, but the requirements themselves can be described using many of the concepts discussed in the lecture this week (i.e. Scalability, Availability, Network performance, Security, Manageability, and Affordability).

Analyzing technical requirements for the customer is important in helping one best fulfill the customer's expectations. The various objectives that need to be fulfilled involve the factors of Scalability, Availability, Network performance, Security, Manageability, and Affordability.

Scalability

Scalability refers to the amount of growth that a network design can support. This is particularly important for large companies that are adding users, applications, additional sites, and external network connections all the time.

I would utilize a number of security measures to adequately secure a central computer network that is accessed by other branches and staff from remote physical location. The vast majority tends to work in conjunction with one another, and should not deny access to authorized users.

For all of the computers that are present in the primary, physical location in which the network is based out of, I would employ encryption measures. This sort of encryption is similar to that used by cellular devices (whether in the form of tablets or phones), which enables users to reduce the threat of unauthorized users from accessing their devices or the data within them (Stafford, 2010). However, it is worth noting that encryption would not be used on the computing devices in the network that are outside of this primary physical location.

Knowledge of e-crime from the perspective of crime science is insufficient in devolution of the problem, which cuts across various sections of social interaction through computers. There is a limitation in the forensic and social / legal exploration of information technology aspects and that is the possible cause of the limitations of the jurisdictions of the computer crime legislation, creating the insufficiency in the fulfillment of its purpose (Tonry 2009 p. 20-350).

The legislation approaches the infringement of the social precepts of technology without any consideration of social remedies. The use of police in regulation of operations is limiting because they may not have the capacity for gauging the extent of computer damage.

New Computer System for the 21st Century Business Office

It is impossible to imagine that any business can be run in the 21st century without an adequate computer system. And yet therein lies the rub: Determining what computer system is adequate for any business purpose is in fact a complex and difficult process in many cases. All too often what happens when a manager is faced with choosing a new computer system (usually at the point when the old one has completely crashed, losing valuable information that wasn't backed-up) is that he or she finds the brochure that's on the top of the pile and orders that computer system.

But this is not the way to proceed. Acquiring the right information system is essential in keeping a company healthy. This paper examines a real-world case of a corporation - in this case, Toys Us - adopted a new computer information…… [Read More]

Computer Systems Are Increasingly Being Used to

computer systems are increasingly being used to cause widespread damage, with nation-states or individuals sponsored by nation-states making use of malicious codes to compromise 'enemy' information systems. In essence, cyber warfare has got to do with the attack on the information networks, computers, or infrastructure of another entity by an international organization or nation-state. In the context of this discussion, cyber war will be taken as the utilization of "coordinated attacks to specific critical sectors of a country" (Edwards, 2014, p. 67). The key aim of such attacks is usually sabotage or espionage. This text concerns itself with cyber warfare. In so doing, it will amongst other things analyze a journal article titled, Stuxnet: Dissecting a Cyber Warfare Weapon, by alph Langner.

Computer Mediated Communication CMC Throughout the Years

Computer mediated Communication (CMC)

Throughout the years, people used different means of communication to pass information from one source to another. The type of communication involved face-to-face, writing letters then sending to people, using telegrams which was the quickest means of communication, and use of telephones, although telephones were invented some years back. Today, the world has become computerized and there are new technologies that most firms have acquired to ease communication as well as replace labor. The computer mediated communications (CMC) that emerged involved the use of e-mail, chat rooms, and Usenet groups. In summary, this paper gives a narrative regarding the issue of Computer Mediated Communication as well as, analyzing the linguistic and visual features of my topic while explaining how they affect communication.

Network It Communications Selecting the Type of Cable

Network/IT Communications

Selecting the type of cable to be used when developing a LAN from the ground up can be a complex process with many considerations, including issues of functionality and of cost. Twisted pair cables provide a cheaper alternative to other cable types and are also the most flexible type of cable, but they are less secure and are more prone to losses in data integrity than are other standard cable types (Hsieh, 2012). Fiber optic cables provide the best protection against interference and are the most secure cable for use in a network, but the cost can be prohibitive and the heightened performance aspects are not necessary in all applications (Hsieh, 2012). Coaxial cables come in two varieties, thinnet and thicknet, with thinnet being both cheaper and more flexible than twisted pair cables (though still more expensive and less flexible) and also provide a decent amount of security…… [Read More]

Computer Addiction Causes and Potential

This is what creates the continual need to share literally everything going on in their lives, as each post releases a significant dopamine rush (Charman-Anderson, 17, 18).

Dopamine is also the reason why the many forms of computer addiction are so difficult to treat. ith anonymity comes the opportunity to create multiple identities or personas online (Soule, 66, 67). This is what leads employees who have Internet addictions to create many different online identities, giving them ethical and moral leeway they would never give themselves. This aspect of personas and the forgiven unethicacy of conduct of personas is a key factor in online crimes committed by employees during company hours (Nykodym, Ariss, Kurtz, 82, 83). The personas of the addicted computer addicts are orchestrated for specific dopamine-driven production to fuel and feed habitual behaviors online

(Quinn 180). These strategies to ensure a steady supply of dopamine may not even be…… [Read More]

Computer History Museum: A virtual visit

Description of the event

The Computer History Museum has both an online and a 'real world' incarnation. It is a physical warehouse of different types of computers, a virtual catalogue of computer history throughout the ages, and also provides information about specific topics pertinent to computer history, such as the history of video games. The Museum contains artifacts such as the first calculators, 'punch cards' and online computers as well as information about their place in computer history. It makes a convincing case about the ubiquity of computers in everyday life from an early age, even though the contrast between the primitive nature of early computers and computers today is striking.

There is also a stark contrast between the functionality of early computers and computers today. The computers we use on a daily basis are multifunctional. People demand that their smartphones do everything from…… [Read More]

Network Security as an Issues for Business Data Communication

Network Security: An Issue for Business Data Communication

Computer security and the protection of data has been an issue since the early 1980s when computers became standard office equipment. Company sensitive information is stored on computers. Protecting the access to and integrity of this information has been a key concern for managers and computer specialists alike. The issues in data security have not changed, however the advent of the Internet has made keeping data secure more difficult. The Internet did not change the key issues, just the number of users trying to access the information. Network administrators have been facing these issues for quite some time.

The key security issue facing IT professionals is to protect the system from invaders or intruders known as Hackers. Hackers can be grouped into several categories according to motive. They are Joyriders (who do it for fun), Vandals (who do it to cause harm),…… [Read More]

Network Research Encountering -- and

The behavior of both botnets and worms in peer-to-peer networks have been empirically examined and models or simulations of their behavior have been attempted, and the manner in which different nodes in peer-to-peer networks develop in and of themselves and in terms of their relationships with other nodes -- the very architecture of the network itself, in other words, which is necessarily dynamic in a peer-to-peer network -- makes it easier for these threats to spread and evolve undetected due to this architecture and to the patterns of information flow over such networks (Fan, 2011; Xu et al., 2011). When it comes to worms propagating in peer-to-eer networks, the activity of the worm itself has been demonstrated to be the most necessary knowledge in terms of tracking and preventing the continued spread and damage of such a threat, while botnets generally show more "robustness" an are better impacted by shifts…… [Read More]

Conclusion

The purpose of this discussion was to examine the network security measures that are available. The research found that the proper configuration provides the first line of defense as it relates to securing a network.

In addition, firewalls serve an essential role in securing networks against outside intrusions. The research also indicates that anti-virus software, encryption software and biometrics allow organizations to secure networks in a more comprehensive manner. There are also specific strategies and technologies that should be considered if an organization chooses to use a wireless network.

Network System Analysis

Natividad Medical Center was established in 1844 (NMC Profile). It is a licensed hospital for 172 beds and employs approximately 800 employees. Natividad Medical Center serves more than 135,000 patients with a wide range of inpatient and outpatient services, including Doctor Clinics, surgery, lab, as well as emergency services, and handles more than 42,000 emergency visits annually. The hospital industry is governed by laws and regulations that require a high amount of security by the facility, employees, and the information system, such as Health Insurance and Accountability Act (HIPAA) (Dennis, 2005). HIPAA requires individual user authentication, access controls, audit trails, physical security and disaster recovery, protection of remote access points, such as individual computers in the hospital, secure external electronic communications, software discipline, and system assessments. The medical record storage and input interfaces are required to maintain high levels of security.

Computer IBM Entered the Computer

To some users of personal computers, who state, never trust a computer that you cannot lift; the IBM has been viewed, more often than not, as an enemy, and according to Byte, the computer magazine, this was because of the fact that the IBM company rose to fame mainly on the basis of its mainframe computers, that were large and forbidding, and overwhelmingly bulky. This was probably why, when the rest of the world was eyeing the emerging opportunities in the minicomputer market, the IBM never paid any attention, and even though IBM did succeed in capturing a large chunk of that market, it did not happen until Digital had captured the minicomputer market and had grown into a large corporation.

In the past few years, IBM has agreed to change the ways in which it conducts its business, and adapt to the changing times when the prices of computers…… [Read More]

Subtopic 6: Job management and protection; include a serious discussion of security aspects

The most commonly leveled criticism of operating systems is the inherent lack of security they have (Funell, 2010). Defining operating systems to have partitioned memory is just the start, as Microsoft learned with their Windows NT platform. Dedicated memory partitions by user account can be hacked and have been (Funell, 2010). The need for greater levels of user authentication is required, including the use of biometrics for advanced systems that have highly confidential data within them. The reliance on security-based algorithms that also seek to analyze patterns of use to anticipate security threats are increasingly in use today (Volkel, Haller, 2009). This aspect of an operating system can capture the levels of activity and the patterns they exhibit, which can provide insights into when a threat is present or not. The use of predictive security technologies, in…… [Read More]

Network Neutrality Has Become One

" (u)

The view opposing non-neutral networks is also articulated by one of the founders of the Internet, Vinton G. Cerf. "Allowing broadband carriers to control what people see and do online would fundamentally undermine the principles that have made the Internet such a success. "(Prepared Statement of Vinton G. Cerf...)

hile the cable and telephone companies do present some cogent practical and legal points, yet their rationale cannot measure up to the serious issues of democratic freedom and free access to information and content that a neutral network ensures. hile there is no perfect solution to this problem probably a middle ground could be worked out where the companies receive some control but do not infringe on the essential rights of freedom of expression and information.

Network Monitoring Network Activity According

The responses to a network security monitoring attack needs to be based on an assessment of the method of the attack that is being leveled against the network and its security monitoring, and thus can be as varied and complex as the attacks themselves (Bejtlich, 2004). Two tactics or tools that an attacker might use to attack network security monitoring are an attack from a stepping stone or an attacking using a spoofed source address. Both of these are methods by which the attacker uses tools and processes to hide their location and identity, making it more difficult to trace the origin of the malicious activity and thus to end it and also causing problems when it comes to the legal end of proving and prosecuting crimes. There are numerous methods of addressing attacks that utilize such tools, including different ways of attempting to track the true and hidden identity…… [Read More]

Computer Mediated Communication Contrary to

My significant other and I met in a traditional manner, at a nightclub.

Furthermore, most of our early relationship was spent in a conventional manner; we dated and spent time with each other, using CMC, such as texts and IMs as a way of relaying information about how we would spend our face time, rather than using it as a way to replace face-time. Then, life intervened, as it so often does, and an internship opportunity across the country separated us. Both of us being relatively poor students, we are unable to fly to visit each other frequently. Furthermore, while cell phones and unlimited calling plans have made it possible for us to talk a lot of the time, we have conflicting schedules, which can make it difficult for us to arrange times for any type of lengthy conversation. However, we can spend time e-mailing each other, devoting time to…… [Read More]

The main lesson learned from viewing the tutorials and programs is the ease and flexibility of configuring each specific session to the unique needs of an audience. Feasibly these technologies could be used for creating highly unique and tailored learning experiences for students who were learning through online universities only for example. The ability to tailor all forms of digital content, from music and video to drawing boards and the inclusion of self-pacing materials, shows the potential of these technologies to support online learning over an entire semester for example (Suduc, Bizoi, Filip, 2009). The implications on long-term learning using these technologies is also significant. It is clear that the recursive nature of how they are designed would allow for repetitive study of complex concepts, including the more challenging areas of math, statistics and the sciences.

Network Dating Sites How Type Dating Evolved Include Pros Cons

Network dating sites. How type dating evolved . Include pros cons.

Network dating sites have gained a particular place of social eminence within contemporary times. Online dating sites that members pay to use, such Match.com, made over a billion dollars in 2010 (No author). Many people consider these websites as primary options for dating for the simple fact that they allow expedient access to other singles who are also looking to date. Interestingly enough, these sites seem to have evolved from more conventional advertising for dating, which was traditionally found in print resources such as newspapers and weeklies. One may argue that the development of social networking web sites played a considerable role in the formation and popularity of network dating sites. Despite the degree of popularity these sites have, there are some inherent drawbacks associated with them that somewhat mitigates their efficacy. The most salient of these revolves around…… [Read More]

Computer Clustering Involves the Use of Multiple

Computer clustering involves the use of multiple computers, typically personal computers (PCs) or UNIX workstations, multiple storage devices, and redundant interconnections, to form what appears to users as a single integrated system (Cluster computing). Clustering has been available since the 1980s when it was used in Digital Equipment Corp's VMS systems. Today, virtually all leading hardware and software companies including Microsoft, Sun Microsystems, Hewlett Packard and IM offer clustering technology. This paper describes why and how clustering is commonly used for parallel processing, batch processing, load balancing and high availability.

Despite some challenges such as achieving transparency, mitigating network latency and the split-brain problem, clustering has proven to be a huge success for bringing scale and availability to computing applications. Hungry for even more efficient resource use, IT departments are now turning their eye on the next evolution of clustering called grid computing.

Once all of the hardware and networking is completed then this will represent the projects second major milestone.

The final project stage will be the one most prone to delays by it project historical standards. Since these are standard network servers however the project estimates that these can be installed in a relatively short amount of time. In fact, the budget estimates allowed for the servers to come fully installed with server operating systems directly from the factory. However, the project could potentially be altered in the software planning phase if it was deemed that purchasing the servers' operating systems separately provide any substance advantage.

To conclude the discussion of the projects activities, we will again revisit the project milestones; the first is the completion of the renovations to the floor designated to host the servers, related equipment, and personnel. The second milestone will be reached when all of the…… [Read More]

Network Events, Alarms, and Alerts

It's not at all difficult to name and describe an event category or event-based transaction that can trigger an alert, alarm, or otherwise cause a network management system to bring something to the attention of a network manager; the difficulty is in limiting the description of such categories and transactions. Depending on the specific needs and architectures of the network and its users, the type of event or event-based transaction that might lead to the notification of a network manager could be pretty much anything. There are, however, some common event categories and event-based transactions that will trigger alarms or other notifications in the network management system and require attention form network managers. Several of these event and transaction types will be identified and described in the following pages, with their relevance discussed.

One broad category of events that commonly triggers alarms are…… [Read More]
