...In this chapter I will be talking about the user side and server side factors that influence the performance of a website. User side factors Processor Speeds The Processor of the computer does affect webpages. The reason why webpages are affected by this is that if the computer system has a processor that is not very fast, then it will take more time complete the tasks at hand. The processor is the metaphorical brains of the computer, as it specialises in processing tasks. If comparing a Pentium to an i3, then it would be a modest increase in processing capabilities. Comparing a Pentium to an i5 then it has a major increase in speed. Comparing a Pentium to an i7, then the difference in its capabilities would be quite extravagant. Cache Memory There’s a type of memory that the computer uses which...

...software utilities (P3) and explain how software utilities can improve the performance of computer systems (D1) Security Virus Protection is in place to protect your PC from any sort of viruses that may infect and harm your computer. Viruses can come in many different forms and can be hidden in different ways to get into your computer. A virus protector will scan through any files/links/websites that are opened on your computer to detect viruses from a ‘dictionary’ of known viruses. If a virus was to infect a PC the effects on the PC can be irreversible and very harmful. It is important to have virus protection running on your PC as even though in rare cases this slows down the computer, the prevention of virus infection is vital to the security of your PC. Firewalls are in place to protect your computers server and keep its identity hidden when using unknown servers to connect to the internet. They also monitor ingoing and outgoing data and anything that could be harmful to your PC is scanned for viruses/malware. Firewalls improve the performance of the PC as they filter through any communications between servers and blocks and malicious communication attempts. They can also be programmed to block certain types of websites and servers to aid even more to the prevention of your PC being infected.

...Computer Information Systems Paper Charles E. Jones Jr. CIS/319 Version 8 April 29, 2012 Ike Shia Abstract This paper is to focus on the accuracy, convenience, different types of storage methods, and the roles they play as far as the speed of the systems. Throughout the paper it discusses the best input and output methods for various hardware and software. Accuracy of Data Accuracy of data input is important. What method of data input would be best for each of the following situations and why: As far for printed questionnaires the best method for data input would be a keyboard, because it permits one to produce the required test that formulates the questionnaires. The best method for a telephone survey would be voice recognition and recording system because a voice input device can be programmed to distinguish and record answers spoken into the receiver allowing it to all be computed. Bank checks would best be used in a scanning method that recognizes bar codes. To be more specific a magnetic scanning input device would be the exact system to use. This system reads the numbers at the bottom of the checks and will mechanically make modifications to the correct accounts. It will input the codes in a system will magnetize the information at the bottom of the check for simple interpretation. For retail tags the best data input for would be a bar code scanner as well. This specific scanner is called an optical scanning input device. By using a bar code scanner it...

...single infrequently used Microsoft Office document is unlikely to have an impact on overall system performance. However, fragmentation of a paging file, which provides virtual memory to all applications on a system, will likely have a more noticeable impact. Desktop Storage • Storing files downloads and programs on your desktop will affect the performance of your computer. Spyware • Spyware is another major factor affecting computer performance. Spyware is malicious software that attaches itself to your computer in various ways to advertise, monitor your Internet behaviors or collect personal information. System Registry • All Windows computers have a system registry that stores the settings of all software and hardware on the computer. The accumulation of these unused files will affect the performance of your computer. Disk Space • Every time you visit a Web pages through your Web browser the page is cached for easy access the next time you visit the page and a temporary Internet file is created on your computer. These files over time can clutter your hard drive and affect the performance of your computer. While there is little dispute among IT professionals regarding the impact of disk fragmentation on system performance, no independent guidelines exist to recommend the frequency of defragmentation across an infrastructure. Some IT professionals use defragmentation as a measure of last resort, defragmenting only after system performance has sufficiently degraded to...

...What are the major components of the motherboard? Provide a brief description of each component. The processor is the chip where all the computing is done also known as the brain of the computer. The memory or SIMMs (single inline memory modules) are commonly used to store information the computer is working on. The chipset controls the hard drives, USB ports, and generates sounds the computer makes. Expansion slots let you attach additional cards through connectors like video, sound, and modems. The I/O bank lets you connect devices to your computer through a set of connectors. Upgrading only the motherboard will give some performance improvement to a computer system. Why would the improvement be limited? This improvement is limited because just upgrading the motherboard doesn’t upgrade the speed vastly if you don’t upgrade the Ram your computer will possibly running just as slow as it was before. What is the need for all the different busses found on a motherboard? Why can these busses not be replaced with a single bus? You need different busses on your motherboard because there is simply too much exchange or flow of data for just one bus therefore you assign them they’re own devices or jobs to keep the performance of the computer from slowing down. With 64-bit busses available, why should 32-bit busses be provided as well? If your system is older it may require the use of 32-bit busses instead of 64-bit busses because it they just are not compatible with newer...

...MODERN-DAY ACCOUNTING Before the existence of technology, there was mechanized bookkeeping, keeping track of financial transactions, and their ultimate effect on a business, was a matter of sorting transactions into the proper category and recording them by hand into proper ledgers, using specialized paper to physically emulate the T-Account concept. This involved a lot of workers (accountants) to prepare the accounting records and this led to the management of the organization paying a lot of wages and salaries to the many workers which meant incurring so much cost and slow decision-making. But now, in the field of accounting the story has changed. There had been a lot of changes over the years. The changes include the following: * The existence of Computers and Internet Access: Computers have enabled the works of accountants to be less tedious. The usage of computers is also time-saving. Via internet access, managers of companies can be up-to-date about the financial statements and records of their many branches scattered all over the country without the need to travel to those branches. This is possible through networking and tele-conferencing. * The presence or existence of accounting software packages: accounting packages have also been developed for modern-day accountants to suit their organizational needs for quick decision-making. It ensures the easy computation and analysis of financial data. It also helps to locate and eliminate errors. It helps to produce...

...infrastructure spans international boundaries to make the internet a worldwide phenomenon available in any region that has a functioning localized network. In information technology and on the Internet, infrastructure is the physical hardware used to interconnect computers and users. Infrastructure includes the transmission media, including telephone lines, cable television lines, and satellites and antennas, and also the routers, aggregators, repeaters, and other devices that control transmission paths. Infrastructure also includes the software used to send, receive, and manage the signals that are transmitted. In some usages, infrastructure refers to interconnecting hardware and software and not to computers and other devices that are interconnected. However, to some information technology users, infrastructure is viewed as everything that supports the flow and processing of information. The limitations of the internet’s infrastructure are as follows: * Bandwidth limitations * Quality of service limitations * Network architecture limitations * Language development limitations * Limitations arising from the “wired” nature of the internet Bandwidth limitations are the reason why the internet can be slow. The internet is incapable of displaying and sharing...

...To coordinate an Ageing Society and eHealth Richard Hobbs r.j.hobbs@umail.leidenuniv.nl Abstract— Scientists have done a tremendous amount of research on the subject of eHealth related to our ageing society. The main causes behind the slow adoption from ageing society to new technologies, such as smart phones and e-commerce, have been researched. There is not a main common cause amongst scientists for this slow adaptation. What are the possible main causes behind the slow adaptation for the elderly to new technology? The aim of this research was to analyse and come to the most common cause indicated by several researchers as to why the ageing society is slow to adapt to new technologies. The results were quite surprising and differed from our original argument. It was assumed that the ageing society was slow to use technology because they were complacent. A literature review of a number of mainly scientific articles on the topic of the ageing society and their slow adaptation to eHealth has been done, from this we were able to conclude that ergonomics and interface problems were the most common causes. It is important to figure out the causes of the slow adaptation to find possible market opportunities and to adjust the upcoming technologies for the ageing society. Keywords— eHealth, ageing, adaptation, elderly people, ergonomics Introduction Presently Information Technology is becoming a more dominant part of our daily routines; nearly all of what...

...Computing Cloud computing is becoming the "solution" for businesses. It is revolutionizing how businesses work & get things done. Before cloud, computing was ever thought of, businesses worked from their own computers, licensing tons of software & people complaining that their computers were too slow to handle the proper tasks they needed to get finished. Fast forward years later, now were in the cloud-computing era. The era where people can access tons of applications through a remote server. Where companies can save money, license the program they need once & where there are no complaints about it being slow to the extent where they cannot use certain programs because of memory issues. There are tons of advantages cloud computing has in the business world & that is what I will be elaborating on throughout this essay. When talking about cloud computing in the business world, it is helpful & understandable to divide it into two sections, which are the front end & the back end. They connect to each other through a network. The front end is the side the person see's, like the computer & the applications used to run the computer & which ones to access the cloud. The back end consists of various types of technology such as the computers, the servers & the data storage systems that create the cloud. This architecture is involved for creating a cloud-computing environment. A cloud-computing environment is especially great in the software aspect...

...Hourglass Syndrome There is a new medical condition now known as Hourglass Syndrome. What is this? It is a syndrome that you receive waiting on your computer to do whatever tasks you has told it to do. Yes waiting for a computer to load your documents or web sites can get a little frustrating, but do we really need to create a name for it? Even worse, do we need to label it a syndrome? According to Intel, we wait approximately 13 minutes per day using our computer. This relates to 3 days per year totally waiting. How relevant in our lives is this? Do we wait longer than that in the line of Wal-Mart buying groceries? Should we then have a label of line syndrome. There are so many labels out there all ready, should we create another. If so we could have hold music syndrome, and phone automation syndrome, and the press 1 for English syndrome. Labels do not do Americans any good. Most Americans seem to equate the word syndrome with a reason to act out. Television most recently expresses this with a commercial by GameFly. This is a company that rents video games similar to the company NetFlix. The commercial shows teenagers and adults acting crazy and throwing their televisions out windows due to buying a bad video game. Society teaches us to act as spoiled brats if we don’t get our way. The word syndrome seems to help Americans with an excuse to act out in this way. Our society does not show the ability to function as true adults. Everyone seems to want...
