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. More specifically, the text will conduct a technical analysis of the said article and discuss not only the offensive and defensive Cyberware strategy, but also make recommendations on…

System Security and Internet Privacy

Personal computers have become an important component of today's society given their role in helping stay connected with the contemporary world. Actually, computers are currently used for a wide range of purposes and across a variety of settings. Consequently, computers are used to keep personal information, which implies that they have become critical parts of everyday life. However, the use of computers requires ensuring privacy in order to guarantee the security of information. Computer users are constantly faced with the need to ensure the security of their systems through implementing various measures towards systems security.

System Security

I have just received a new computer for my home environment and can easily connect to the Internet and perform some online banking through the already existing Internet Service Provider. However, I need to ensure systems security in order to promote security of personal information, especially banking information.…

According to aul B. Mckimmy (2003), "The first consideration of wireless technology is bandwidth. 802.11b (one of four existing wireless Ethernet standards) is currently the most available and affordable specification. It allows a maximum of 11 megabits per second (Mbps)" (p. 111); the author adds that wired Ethernet LANs are typically 10 or 100 Mbps.

In 1997, when the IEEE 802.11 standard was first ratified, wireless LANs were incompatible and remained vendor specific; the 802.11 protocol representeded an important step towards standardization (assmore, 2000). Wireless local area network (LAN) technology, however, has actually been in use since the late 1980s; different proprietary approaches were commonly used, and the networks operated at lower speeds (e.g., 1-2 Mbps). In 1997, though, the standards setting body, IEEE, released the 802.(11) standard for wireless local area networking using the unlicensed 2.4 GHz frequency band (as opposed to the 900 MHz band used in the…

CBU installed a computer system tracking calculating inventory costs. On December 31, ye

In my opinion, it would be relatively easy to explain the diverse opinions regarding the efficacy of the new computer system for tracking and calculating inventory costs at CBU. There is actually a degree of rectitude found in the opinions of both accountants A and B. There certainly is validity to accountant A's viewpoint: that the auditing team was able to find a discrepancy between the amount of the physical inventory and that which was recorded on the new system for this organization (the difference was a million dollars). It certainly would not have been prudent to be unaware of such a discrepancy, and to have the books erroneously balanced due to such an error. Therefore, from this basic perspective accountant A actually has a good point.

However, it largely appears as though this accountant has taken…

Strengths and Weaknesses of Recommended Information Systems

Comparing Record Store Computing Systems Cost and Benefits

Baby Boomers who are nostalgic for music from the 60s, 70s and 80s are a lucrative market for a record store. Many of these music fans are also big fans of the classic nostalgic music from the 1950s, which include many of the classic rock and roll pioneers including Elvis Presley, early Johnny Cash recordings, Richie Valens and Buddy Holly. he demand for music from these periods is very high given the tendency on the part of people in general and Baby Boomers specifically to prefer music from less complicated times.

What's very important to realize about these purchasers is they have a completely different series of information channels they go through to learn about music vs. how they…

Human Element

Computer systems design has come a long way from the time when Dijkstra first began exploring time sharing mechanism in the workings of the keyboard. In his day, computers were the realms of scientists and technical people. Operating systems designers were more concerned with processing ability. Human factors and "user friendliness" were terms that would not be a part of their vocabulary for many years to come. At the time of their early work, most of the population was still amazed at the automatic toaster and the television. Many early designers did not think about the common person eventually becoming a consumer of their product in a major way.

Dijkstra had vision beyond his time period and was one of the first to consider human factors in systems design. The first concept to be considered was the reduction of time spent waiting for the system to process the…

As many of the components of our current computer system are more than five years old, there could be a significant cost savings produced by replacing and updating the system, in addition to the extra revenue generated by increased productivity (Meredith, 2010).

I have already begun preliminary investigations as to some of the specific components, processes, and features that might be desirable in this new system, and am awaiting your approval to conduct further research and feasibility analysis with this project, to eventually lead to the development and implementation of the system. I am very optimistic that this project could ultimately help to drive this company to new heights, capable of more fully capitalizing on emerging opportunities.

Respectfully yours,

Mr. Cubicle

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.

The subject matter of systems administration includes computer systems and the ways people use them in an organization. This entails knowledge of operating systems and applications, as well as hardware and software troubleshooting, but also knowledge of the purposes for which people in the organization use the computers.

The most important skill for a system administrator is problem solving. The systems administrator is on call when a computer system goes down or malfunctions, and must be able to quickly and correctly diagnose what is wrong and how best to fix it. In some organizations, computer security administration is a separate role responsible for overall security and the upkeep of firewalls and intrusion detection systems, but all systems administrators are generally responsible for the security of the systems in their keep. (Encyclopedia.com, 2011)

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…

Attacks on the system security include password theft, back doors and bugs, social engineering, protocol failures, authentication failures, Denial of Service attacks, active attacks, botnets, exponential attacks including worms and viruses, and information leakage. (Fortify Software Inc., 2008); (Fortify Software, n. d.)

Servers are targets of security attacks due to the fact that servers contain valuable data and services. For instance, if a server contains personal information about employees, it can become a target for stealing identities. All types of servers, which include file, database, web, email and infrastructure management servers are vulnerable to security attacks with the threat coming from both external as well as internal sources.

Some of the server problems that can jeopardize its security include: (i) Weakly encrypted or unencrypted information, especially of a sensitive nature, can be intercepted for malicious use while being transmitted from server to client. (ii) Software bugs present in the server…

As many of the world's industries are faced with increasing competitive pressure and the need to continually improve their performance, employers look to new employees with computer fluency skills as an indicator that the person also has initiative to tackle difficult learning projects and master them. Initiative is very valuable in today's labor market. When combined with computer fluency and literacy, a prospective employee can add in knowledge of a specific industry and gain a greater competitive advantage in getting a new position. This combination of factors together is what serves as the catalyst for anyone seeking a career where computer fluency is a necessary requirement.

Summary

The level of computer literacy and their level of fluency with PCs, applications, the Internet and its many applications and research tools will have a direct correlation to what they will earn over their lifetimes; this point is clear from the studies citied.…

Computer Fraud and Abuse Act was enacted into law in 1986 to deal with the hacking of computer systems operated by the American government and certain financial institutions. Through its enactment, the legislation made it a federal offense to access a protected computer without authorization or to an extent that is beyond the authorized access. However, since it was passed into law, the act has been amended severally in attempts to expand its scope and penalties. In addition, the act has developed to be an important legislation since it's used widely not only by the government to prosecute hackers but it's also used by private corporations to help protect their trade secrets and other proprietary information.

Penalties and Fines in the Law:

The Computer Fraud and Abuse Act is considered as one of the most essential computer-crime laws because it was the first significant federal legislation to offer some protection…

Computer-Based Crime

The illegal site I reviewed for this assignment is www.howtogrowmarijuana.com. This site covers virtually all aspects of marijuana growing -- which is an illegal activity because marijuana is widely outlawed in the United States. However, there are some states in which individuals can legally consume marijuana for medicinal purposes. In these states and others there exists the potential for businesses to legally supply this substance to people.

There is a large degree of transparency in this particular web site. It was the first result to appear with a Yahoo search for "How to grow marijuana." As the tile of the site suggests, it discusses many different facets of growing marijuana and stratifies this process according to location (indoor or outdoors), various strains of marijuana including seeds (No author, 2014), irrigation and growth systems involving hydroponics, and other germane equipment types such as the expensive lights used to assist…

However, the company did feel it should develop its own Database infrastructure that would work with the new underlying database management system and would mesh with existing organizational skills and the selected enterprise software solution.

Because the company followed a standardized implementation process, they were able to successfully reengineer their existing business structure. The objective of the System Development Life Cycle is to help organizations define what an appropriate system development methodology should be in order for them to continue to meet the rapidly changing business environment. The specific research approach employed by International Lumberyards, Inc. was to follow the steps of the cycle and it helped them dramatically.

Conclusion

This report attempted to analyze a work-related project that used a systems analysis tool for a specific business system. The report focused on the use of the System Development Life Cycle to implement a business or information technology need as…

(Andrews, 1985)

The study found that computer charting was well accepted by therapists. "Charge capture was reduced from a four-step manual process to a single-step computer documentation of the procedure. Computer charting was more complete and informative. Productivity increased 18%, although it remains unclear to what degree the computer was responsible." (Andrews, 1985)

In conclusion, the study determined that computer charting streamlined the process of documentation and allowed more beneficial use of clinical information. (Andrews, 1985)

In other words, the study fell in line with the later Cunningham study in that they both noted that computer involvement in various stages of health care provision via computer charting truly benefits the health care provider and the patient. In addition, it streamlines costs and eliminates costly errors.

College health systems benefit especially from computer charting, according to Carol Mulvihill, R.N.,C., CQ Editor and Director of Health Services, University of Pittsburgh at radford.…

Moreover, it has also to be ensured that the motherboard contains expansion slots built into the board, and not built into the expansion board which plugs into the motherboard.

Memory: The memory located inside the computer is called as the andom Access Memory (AM). This AM is place where CPU temporarily stores information, which it needs to perform a function. The quantum of memory is directly related to the extent of complicated functions it is able to perform. It is important to get a system having at least 256 MBs AM or 512 MBs or higher is preferred. For the greater part, the more memory to which the system can be upgraded to in future is better. The latest software programs are always extremely resources hungry.

In the same year, the founders started a new company for computer development called the Eckert-Mauchly Computer Corporation. By 1949, this company launched the BINAC or Binary Automatic computer. This computer made use of magnetic tape for the storage of data. Then this company was bought by emington and Corporation and the name was changed to Univac Division of emington and. This company was the organization to bring out UNIVAC which is one of the originals of the type of computers that are used today.

Network gives us two basic advantages: the facility to communicate and the facility to share. A network helps in communication between users in better ways than other media. E-mail, the most well-known form of network communication, offers inexpensive, printable communication with the facility of sending, reply, storage, recovery, and addition. Network supports collaboration with its capacity to share. This is the main charm of popular software called groupware that is created in such a way to allow many users to have electronic meetings and work alongside on projects. (Basic Networking Concepts)

Internet is a network of computer networks, upon which anybody who has permission to a host computer can circulate their own documents. orld ide eb is one such network, which permits Internet publishers to connect to other documents on the network.

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. It is logical considering the sensitivity of pro-social individuals, and their possibility of taking up their responsibilities. Social norms revolve around consideration of others and create a sense of mindfulness and consideration of activities (Humphreys 2007 p.…

computer used by the employee has either been compromised physically with a password cracking software (EC-Council,2010;Beaver & McClure,2010) or it has bee compromised remotely with the help of a keylogging software.A keylogger is noted by APWG (2006) as a special crimeware code that is designed with the sole intention of collecting information from the end-user terminal. The stolen information includes every strike of the keyboard which it captures.The most sensitive of the captured information are the user's credentials. Keylogger may also be used to refer to the hardware used for this purpose. The employee's password could also have been shoulder-surfed by his immediate neighbor at the workplace. This could be his coworker who manages to peek and see over his shoulder as he types in sensitive authentication information (password)

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…

computer programmers create programing languages, they must make use of data types to create a functional system. A number of different formats of data types exist for their use. Perhaps the most obvious is that of an alphanumeric string, or a string of letters and numbers like ab1cd1. "Alphanumeric is commonly used to help explain the availability of text that can be entered or used in a field such as a password" ("Alphanumeric string," 2014). In contrast, Boolean data types make use of words like and, or, and not, to filter information, expressing notions of true and false. "A user can use Boolean searches to help locate more exact matches in Internet searches. For example, a user could search for computers help and DOS, which would search for any document containing computer help that also contain the word DOS. Performing Boolean searches often help users find results relating more to…

Similar to the suggestions offered by Gahala (2001), rody (1995) identified several traits to be considered when developing a comprehensive professional development program. Among those traits include the reputation of the trainer, the rewards available to the participants, both tangible and intangible, and the support of the administration. Traditional staff development models have required everyone to participate at the same time and in the same location creating problems such as scheduling, travel, space, and funding. intrim (2002) notes that web-delivered staff development allows teachers to log on and participate at the time of day that is best for them and at the pace they are the most comfortable with.

urke (1994) concluded that the use of effective distance education programs for K-12 staff development should be increased to supplement face-to-face in-services due to the positive evaluations of K-12 educators who participated in the electronic distance education in-service programs. However, other…

high quality (error-Free) data entry.

Data entry is a vital part of a number of businesses. As such, it has to be of the highest quality and error-free. While there is generally no guarantee that data can be 100% error-free all the time, the more any data avoids errors the more likely the company will be to provide its customer with a good experience (Kos, Kosar, & Mernik, 2012). Additionally, companies that have data errors can end up in trouble because they are using the wrong details to make decisions about what they can and should be doing to move their business forward. If a company is not focused on entering data in a way that is free from errors (and omissions), that company can get a reputation as being sloppy and not well-prepared to handle its business and its customers (Kos, Kosar, & Mernik, 2012). Consumers who provide data…

Computer technology is continuously improving many aspects in today's world of business. It plays a very important role in the storage and retrieval of information. Among the course of studies from which a student can choose from, a major in Computer Information is important providing further improvements in the role of computer to billions and billions of information.

What can I learn from a Computer Information Major?

A Computer Information Major specializes in developing solutions that concerns information. This includes strategies that can enhance the storage, access, and protection, of diverse types of information. From the Computer Information course, one can have the expertise in finding answers to different information-related problems. The responsibility of handling information issues, whether it concerns storage or access, can be managed by one who majored in Compuer Information

Computer Fraud and Abuse Act

A failed and flawed law

Technology has changed faster than the laws that exist to protect the public. Protecting information, particularly sensitive government information, was thought to be challenging and to pose additional dilemmas in terms of its regulation. With this in mind, Congress passed the Computer Fraud and Abuse Act in 1984. The CFAA "outlaws conduct that victimizes computer systems. It is a cyber-security law. It protects federal computers, bank computers, and computers connected to the Internet. It shields them from trespassing, threats, damage, espionage, and from being corruptly used as instruments of fraud" (Doyle 2014:1-2). The CFAA's provisions ban the trespassing of data; the damaging of or use of threats to damage data; or trafficking in the passwords and other sensitive data of a wide range of computers containing protected information (Doyle 2014:1-2).

The law was passed during the pre-Internet era "as a…

In some areas it will be used for more populist applications such as, in schools to introduce students to the discipline and within an environment that will give opportunity for participation of non-academics in academic discussion.

Conclusion

Computer has in a great deal widened the world's knowledge. As the fastest technology that has ever evolved, it has given opportunity for the children and adults, for personal, academic and commercial use. It has made communication to be easier; people get to know what is happening in the other parts of the world instantly. Information and data entering and saving has been made convenient and even easy.

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…

Computer Dependence

The story of Pandora's Box reveals the dangers that technology brings along with its many gifts. Today, some very interesting cultural changes are beginning to take hold of society that stems from the dependence on technology and the way that it is interwoven into culture. The purpose of this essay is to examine the relationship between computer technology and the corresponding dependence that is created by this relationship. This writing intends to demonstrate that people are too dependent on computers and that more balance is needed in this age of technology where considerable portions of humanity are slowly eroding.

This essay will present evidence supporting this hypothesis and suggest that the reader insist on using logic and deductive reasoning to view this report. Many facts will be presented to persuade the reader that the relationship between human and computer has reached a level of dependence that is unhealthy…

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…

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…

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.

Some nanorobots are being designed as "spray-on computers the size of a grain of sand." Edinburgh University has been working on nanorobots that can be sprayed onto patients as monitoring devices. They may be released for medical use in four years.

Quantum computers, based on principles like quantum entanglement and superposition, use the properties of particles. Quantum bits, called qubits, can process information faster than any existing computer technologies. A quantum computer can process many equations simultaneously. In a smaller space, using less energy, a quantum computer becomes more powerful than any commercial PC. In fact, Hertzog implies that quantum computers will mainly be used in fields demanding rapid data processing like the sciences or in cryptography.

Finally, one of the most promising future developments will be in the realm of artificial intelligence. Artificial intelligence implies computers that can think critically and creatively, like human beings. The potential for artificial…

Computer Contracting

Contracting Opportunities for a Computer Component Manufacturer: Trends in Federal Spending

The pace of technological development is now faster than it ever has been at any other time in human history, and this pace has been steadily increasing for several decades. The emergence of the computer in the first half of the twentieth century could not have foretold the power and mobility that these devices would provide a few short generations later, nor the opportunities that continuing advancement and technological growth would supply to businesses. For Vigilant Technology, a manufacturer of computer components, the opportunities are virtually endless. Selecting the most profitable route forward can be made more difficult by the abundance of choices, yet an examination of the current contracts being offered by the federal government can help indicate the large-scale trends needed for long-term profits, not to mention providing immediate short-term gains in terms of the…

System Implementation - Oahu ase Area Network

System Implementation: Oahu ase Area Network

The wireless local area network (WLAN) in the Oahu ase Area Network is made up of several different subsystems. The inputs to the system will be desktop computers, laptop computers, and embedded systems (fixed and mobile). Each client has a wireless network card that can communicate with an access point (AP). The AP manages WLAN traffic and physically connects the wireless system to the wired local area network (LAN). The wired LAN will then send the requested information back to the access points, which will relay it to the appropriate client (Conover, 2000).

The company is an aerospace engineering firm which means that new design will be an integral part of what they do. The company will be dealing with the design of new technology and it is important that the engineers involved have the best equipment possible. The software is decided, in that they will be using CAD to assist with the design of the technology, but the platform is important because it will have to be able to do more than just run the program. The company has also stated that price is not a large consideration. For the purchaser, this means that the best equipment can be considered regardless of price. Since this is an important project for the future of the company, making sure that the right platform is purchased is of the utmost importance.

System Implementation

The implementation stage of the iordan project may prove to be the most challenging yet, but one that is worth all the effort. It would take a team of experts in various fields to successfully see this stage successfully through to completion, it cannot be a one-man show. Several departments within the organization have to be given priority when it comes to rolling out the new human resource management system. Since this system is automated and rests on an Information Technology platform, the first two departments to consider would be the human resource management and Information Technology departments. All the teams of professionals within these departments would have to be part and parcel of the entire system design and development process. The other departments to consider would be those of finance and operations management as they too are a fundamental part of the organization's decision making framework.

We subtract the second equation from the first and we obtain X-3Y=0

We multiply the second equation with and add it to the third. We obtain 16X+4Y+z=106 and, when added to the third, 36X-6Y=100 or 6X-Y=00.

We now have a new system of equations with unknown variables, as such:

x-3Y=0 and 6X-Y=00. We multiply the first equation by 3 and have 6X-9Y=0. We subtract the first equation from the second and the result is 8Y=00 and Y=5. X=37.5 and Z=03

c. Multiply the 1 stequation by 3 and the second by 5. The result is 66X+15Y+1Z=36 and 50X+15Y+10Z=5. We subtract the equations and the result is 16X+11Z=11.

We multiply the second equation with and the third with 3. The result is

0X+6Y+4Z=10 and 7X+6Y+36Z=4. We subtract the equation and the result is

Computer Fraud and Abuse Act

Information technology and related systems provide multiple benefits to business, government, and individual users. Databases, Internet transactions, and emails contain sensitive customers, employee and operations data that are extremely vulnerable. The following study focuses on various components of IT and related systems used for the storage of information like computers, servers, and website databases. Whilst identifying the ways the date can be compromised and exposed to abuse, the study identifies ways of protecting and enhancing their integrity.

Types of information systems that that hold data

Computers

Computers do their primary work in parts that are not visible when using them. To do this, a control center that converts data input to output must be present. All this functions are done by the central processing unit (CPU) a highly complicated set of electric circuits that intertwine to store and achieve program instructions. Most computers regardless of…

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…

In the second case, failing to maintain the forearms in a horizontal position can also trigger similar problems. This frequently occurs when users maintain their keyboards and mice on their desks instead of using a sliding keyboard and mouse tray. Prolonged use of keyboards and mice in an elevated position relative to the elbow causes wrist problems because of the continual downward bend required in the wrist. The solution to this type of hand and wrist problems is simply to use a pull-out keyboard and mouse tray that allows the user to keep the hands at the exact same height as the elbow without bending the wrist down at all during computer use.

Neck, Back, and Shoulder Problems

Prolonged computer use can also result in neck and back problems through similar mechanisms. When users fail to maintain the proper height of the computer monitor, they have a tendency to look…

oday the prevalent technologies for printing output from a computer include what are called "non-impact" technologies or inkjet and laser-based printing devices.

here are an equally wide range of devices for storage of data and resulting information generated on PCs and laptops. Hard disk drives that often include multiple storage platters where data is written to and read from using read/write heads enclosed in the hard disk enclosure are commonplace. Hard drive manufacturers are increasingly shrinking the size of these hard drives, so much so that in 2008 the first camcorders that have 50GB of hard disk space for recording movies is now available. In addition to hard drives, there is also a growing popularity of flash memory-based drives that have Universal Serial Bus (USB) connections on them. hese are often called "pen" drives as they are small enough to be mounted at the top of a pen (David 2003).…

The programming design class gives the student many tools that they will need on the job, but there is much more to the design process than having the right tools. The ability to apply those tools to the situations that will arise on the job is one of the most important skills that the designer will have. However, this is not always easy to teach in the classroom. Therefore, it is important for the design student to read as many outside sources as possible. They must understand the various philosophies and approaches to the design process. They must understand the strengths and weaknesses of those approaches and how they relate to various customer projects. The computer program design student must develop the broadest knowledge base possible in order to deliver a quality product to the customer.

In setting this plan for implementation and maintenance the ultimate goal for the district within the next five years is the creation of a student-to-computer ratio of 1-1 in grades 3-12 and 3-1 for grades K-2 in accordance with developmental studies for the utilization of technology in lesson and course plans for each respective grade. Computers will be updated on an annual basis, with replacement being taken into consideration every four years. In order to maintain cost-effectiveness, leasing programs and low-cost computer programs will allow students and teachers the capacity to access more applications and content which is relevant to consumers but nearly unaffordable in many educational systems. Low-cost computer programs such as the One Laptop per Child Foundation have been developed in order to aggressively place computers in the hands of hundreds of millions of children around the world, the United States included, in order to aid students in…

Systems Structures Presentation

Electronic health records are common in the modern era of globalization and high technology. Electronic health records can be defined as a collection of health information, in digitized form, of individuals as well as populations. The objective of having health records in digital form is to make them accessible across different health care settings. This enables the patients as well as physicians to obtain health information from their relevant health care facility by simply requesting it to be sent over from the electronic health records that were held at the previous health care facility where the patient had been checked up. The health care facilities today are connected through a variety of network-connected enterprise-wide information systems. These can easily transfer information regarding any patient from one health care facility to another, given that they are connected via the network.

Electronic health records consist of not only technology…

The core competencies identified for this paper include: (1) data management (2) personnel management (3) strategic planning and (4) the ability to create technological innovation. ealistically speaking, a company must integrate all of its capabilities to assess its position in the market, and to determine which if any of its core competencies it must work on developing further to maintain a stable position in a volatile workplace. The computer industry is constantly evolving and changing. To be a leader in the industry one might guess the most important core capability for a computer company to have is innovative leaders and the ability to create and easily adapt to new technology.

With a foundation that includes core capabilities as data management, strategic planning and personnel management, a company could easily do this without hardship.

Future Development Trends

The pervasiveness of the Internet and the increasing availability of development tools for creating analytics applications are together serving as the catalyst for the development of an entirely new set of predictive analytic and modeling applications where the performance of specific strategies can be simulated and planned for (Gounaris, Panigyrakis, Chatzipanagiotou, pp. 615, 616). Second, the development of collaborative platforms based on the Internet is also making the data collection function of Marketing Information Systems much more streamlined that has been the case in the past.

Conclusion

Marketing Information Systems are transforming the accuracy and speed that companies' marketing, sales and senior management can react to market conditions effectively. The growth of these systems is in direct proportion to the increasing speed and uncertainty new markets and market conditions influence company's plans and results.

Computer Vision Syndrome

According to the Computer Desktop Encyclopedia, Computer Vision Syndrome (CVS) is "A variety of problems related to prolonged viewing of a computer screen. Short-term effects include dry eyes, blurred vision, eye fatigue and excessive tearing. Long-term effects include migraines, cataracts and visual epilepsy. Some solutions are to keep reflections and glare to a minimum and to provide a non-fluorescent, uniform light source. Special lamps are available that maintain the proper light around the monitor and generate light at much higher frequencies than regular light bulbs"

With the ever increasing amount of time consumers are spending in front of their computer screens, this disability is considered on of the fastest growing work related health problems in the country today. For many Americans, the problem cannot be left behind at the office. Individuals come home, to spend time surfing the web, corresponding via email, and pursuing various computer-based entertainment…

Hacking, the apolitical counterpart of hacktivism, is also not necessarily a form of terrorism. However, cyberterrorists often use hacking as a tool of terrorism.

Terrorists may be tempted to use computer attacks for several reasons including the following. First, cyberterrorism can be relatively inexpensive. Second, terrorists can easily remain anonymous when they use computer terrorism. Third, the scope of the attack can potentially be larger than physically combative ones. Fourth, cyberterror can be launched and managed remotely and fifth, computer terrorism can garner instant and widespread media attention. Cyberterrorism is not only in the province of international terrorist organizations but may also be used by fanatical religious groups or even by disgruntled employess. Using computer terrorism can also become an adjunct to traditional forms of terror like bombs.

The National Security Agency (NSA) has investigated vulnerabilities in their own systems and have hired hackers to expose weaknesses in their systems.…

The instructor does sit with the student when he or she is training with the devices the FAA approves for the educational computer training. Sometimes a separate computer is used during this process, but the teacher is able to monitor and control the student's flight as well as plan out every detail for him or her at that particular time (United States Gernal Accounting Office, 1999).

For those that are educators, they too have noticed trends with computer-based training. The convenience of learning on the Web has stretched all the possible barriers that occur locally and globally. When it comes to distance learning, the Internet is used to deliver material to the learner, such as Word documents or PowerPoints. However, in other online environments, this is provided through hypertext, which allows the learner more opportunities to explore the information provided as well as to have much interactivity (Khalifa & Lam,…

For the SunLife agents to be successful the accumulated experience and knowledge in the company need to be captured, and applied to the sales cycles and ongoing customer relationships. This is another major gap that is in the approach the company is taking with the implementation of Maestro today as well. SunLife is not taking into account the deep expertise and knowledge within the company to streamline and make more efficient the selling process, and as a result the resistance to change on the part of agents just increases over time. They fail to see the value of making any significant shift in how they view new technologies to help them sell more effectively or continually be trusted advisors over time.

SunLife has an exceptionally strong grasp of technologies and their contributions to each aspect of the insurance sales, account management and risk management aspects of the insurance industry. Several…

Project Management:

Project management is the discipline of planning, organizing, and managing resources that would cause the successful completion of specific project goals and objectives. It is sometimes conflated with program management. Regardless, a program is technically a higher level construct. Any group of related and somehow interdependent projects is key to product management.

A project is a temporary attempt. With a defined start and finish, typically reserved to a specified date, these can be by funding or deliverables, undertaken to meet unique goals and objectives, usually to bring about beneficial change or added value. The temporary nature of projects stands in contrast to business as usual or operations, which are repetitive, permanent or semi-permanent functional work to produce products or repairs. Essentially, the management of these two systems is often found to be quite different, and as such requires the development of distinct technical skills and the adoption of…

System Design: Oahu Base Area Network

The aim of this paper is to examine and discuss the Navy's decision to build the largest local area network (LAN) connecting the U.S. Pacific Fleet using information-gathering techniques and design methods. The system has the capacity to connect sailors and marines within the 102-million square miles of the Pacific Fleet's command coverage. Moreover it will provide the indispensable access for supplying and training the U.S. Navy. The Oahu Base Area Network (OBAN) will be the largest LAN in the world when all the phases are complete. It was started way back in 1998. It is the supporting network for the six naval commands in the Pearl Harbor, Hawaii area. Phase one has been completed. Other phases have begun in San Diego, the Pacific Northwest and the Pacific Far East, following the original business model (Kaylor, 2000). The uniqueness of this system is in…
