The study informs that selecting a computer system to buy is an individual choice, which will differ from person to person. Due to the high rate of technological obsolescence, the value of the computer bought today goes down remarkably in a very limited duration of time period. Therefore the purchase of the Computer must be influenced by the requirement analysis of the usage that the computer will be put to. Therefore, it is wise to buy a computer system which fulfils the present requirement and permits one to upgrade to a better system in future. Prior to going for an upgrade, it is first of all needed to self-question what the benefit from upgrading a particular system is. Thus the study suggests some of the recommendations of important items to concentrate upon at the time of purchasing the computer system.

Issue:

Prior to going for an upgrade, it is first of all needed to self-question what the benefit from upgrading a particular system is. For instance, in case one has run out of space, you most probably wish to upgrade the storage capacity of your computer. On the other hand, in case a particular system does not fulfill the memory needs of a specific application, one would most probably like to upgrade one's computer's memory. Prior to delving into the details of the upgrade, one needs to identify the needs to find out what elements are at present inside the computer. This does not always indicate that one needs to make a detailed list of each of the things that goes into making the system, rather than on the spares that one have chosen to upgrade. The easiest and the extremely correct manner to identify the components at present in a particular system are to look forward to avail the services computer manufacturer. Documentation must be refereed to which might have been supplied with the system, or get in touch with the manufacturer straightaway through telephone or through the Internet.

Discussion:

The purchase of the Computer must be influenced by the requirement analysis of the usage that the computer will be put to. The replies will govern the feature and price of the computer. Creating typed documents, browsing the Internet, checking e-mails and creating simple graphs does not require a latest computer. In case somebody is publishing a book through the use of Desktop Publishing i.e. DTP, engaged in high quality graphics and video, browsing the Internet featuring multimedia, or playing the recent 3-D video games one should be purchasing the most powerful computer one is able to afford. While one determines his requirement specifications, it is crucial not to purchase a lot in excess than one is able to utilize. Due to the high rate of technological obsolescence, the value of the computer bought today goes down remarkably in a very limited duration of time period. It might make more economic sense to substitute your current computer sooner rather than to buy more than one might be using in the following year or a couple of years.

Computers possess a very little value after four or five years down the line. Supposing one buys a $1,600 computer in a particular year and uses it for four years, it is going to cost $300 per year. In case one purchases an $800 computer and budget it for two $400 years, one should be considering a new computer in two years while a $800 computer may be loaded with features which might not be available for the $1,600 computer available today. In case a person is new to computer and still not sure of what one will in fact utilize it for, you may consider a cheap used computer to have a little bit of experience. When one becomes aware about your requirement, one will be able to arrive at a more important choice. It is not advisable for buy second-hand computer as older computers are more problematic to use and will only bother a new user.

Home PCs are considered as an investment in oneself, one career and one's family. One should procure a computer as it permits oneself to perform things one could not be able to perform otherwise. In case one lingers and postpones one's purchase, one loses the worth of that computer in satisfying the needs at the present moment. Being a professional one's time has a value. If a $400 per year is able to save your time and/or enhance one's output, is it worth it. Usually, Computers lets us to perform improved quality of work rather than saving time. It might be also found that one can make different preferences for the use of one's time with a computer. Browsing the Internet might divert some of the time people spent viewing television. Utilizing online reference sources may save one from visiting the library for referencing textbooks.

Selecting a computer system to buy is an individual choice, which will differ from person to person. One should be able to diligently assess one's requirements, an individual's knowledge, and the current monetary resources prior to starting to search for a computer system. Always it has to be bore in mind that computer technology is moving ahead at a blazing speed. Despite procuring the latest and the best system in the market having all the specifications, it will shortly be outdated or come down a great extent in prices. Therefore, it is wise to buy a computer system which fulfils the present requirement and permits one to upgrade to a better system in future. Generally, a 'mid-level priced' computer system is the ideal buy for one's money. A computer system at the higher end does not give value for money and a low-end system will be obsolete very quickly. Some of the recommendations of important items to concentrate upon at the time of purchasing the computer system are stated in the adjoining lines.

Power Supply: It has to be made sure that use of the powers supply is done which fulfils all the needs of the buyer, both present and future. It must have all the connectors necessary to set off internal additions that are made at a later stage. Getting a minimum of 250W power supply 300W or higher preferred. Any compromise made in the power supply could result in some serious computer problems.

The CPU: The microprocessor most generally known as the Central Processing Unit (CPU) is the brain of the computer. The CPU is the one of the most costly parts in the computer and is recognized by a number like 286,386, 486 and Pentium. Every CPU has a number linked with it which is measured in megahertz (Mhz) or gigahertz (Ghz) where maga stands for a million while giga stands for a billion. The more the CPU megahertz number, the faster is the capability of the chip to process information. The older family of CP chips, 486 or below has been discontinued production. Nowadays the most popular of the newer chips are the Pentium IV and Celeron chips made by Intel. Celeron chips are much cheaper compared to Pentium IV depending on the speed. In case one intends to use an immense amount of heavy-duty graphics (e.g multimedia, Autocad) or use for a lot of computer games, the Pentium is the ideal choice or else a Celeron is enough. As a number cannot be copyrighted Intel selected the name Pentium way back in the year 1992 to make a distinction of its chip from other chips in the market.

System Board: The System Board is usually known as the Mother Board. This Board behaves like the communication highway of the computer. Every other components and devices in the computer system are connected to the Mother Board. They utilize the Motherboard to convey and get information. Usually, every Mother Board is devised to host a given type of CPU. For instance a Pentium chip cannot be put into a 486 motherboard. This is the reason for which when one upgrades one's system's CPU with a standard chip, one has also to change the Motherboard-unless the motherboard was particularly devised to deal wit an upgrade. Specific upgrade chips are present that have been specifically devised to take one to the hire processing level without changing the motherboard, but this will not be a genuine upgrade because of the architectural restrictions of the Motherboard.

Each Motherboard has expansion slots built into it. In these slots there are different cards which are plugged into. These cards are computer devices, which appear like mini motherboards. There are different types of cards, which can be fitted into the motherboard, for example video card or sound card. It has to be ensured that the motherboard will allow one to upgrade seamlessly. A lot of the newer motherboards currently have the video card or modem directly build into the system board to decrease manufacturing costs as also lower production cost or enhance performance. It has always to be endeavored that a motherboard containing as many as PCI expansion slots as possible so as to make room for future upgrades. 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 Random Access Memory (RAM). This RAM 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 RAM 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.

Input-devices: - Input devices are employed to enter information and direct the commands to your computer. The two most typical input devices are a keyboard and mouse. At present a 104 and more Windows keyboard is the most common keyboard which is given with new computers. In the right hand lower hand corner of these keyboards is the numeric keypad. It is important to get a keyboard with which the user is comfortable. These days' ergonomic keypads are available which lays a vital part in lowering strain on the hands and wrists by way of naturally lining up the keyboard keys with one's hands. Whereas these strain reducing keyboards are quite costly than their standard counterparts, they more than pay for themselves in the long run by immensely lowering physical damage which can be extremely traumatic and might last a lifetime. The mouse is a pointing device that plays a significant part in Windows operating system. It is utilized to click on to a command or icon or bring up a shortcut menu. Besides, some of the computers might possess a pointing device different than a mouse like a track ball or touch pad. One has to select a pointing device with which one can work with ease.

Hard Disk Drives: A Hard Disk drive is the physical location where programs and data are kept. It is situated inside the computer system. The two types of standard hard disk drives are SCSI and IDE, with the IDE being more widespread in PCs. An IDE disk comes at $30 to $100 less than SCSI drives and is simpler to configure and is perfect for an individual desktop computer. In case the system to be purchased is to be used as a network server which needs maximum expandability, SCSI must be seriously considered. It has to be made sure that the biggest hard disk drive one can afford to buy is purchased. The price of a hard disk drive is at present sufficiently below $0.10 per megabyte. It has to be ensured that a minimum hard drive of 20 GB, a bigger one in case is possible. Computer software programs are over the years getting bigger or more complicated. The latest software suites can at present consume in excess of 120 MB of space. If a digital camera is used, the images loaded can simply fill up the hard disk.

Floppy Drives: These are smaller forms of hard drives and have become optional on some of the recent systems. The density of the standard floppy drive is 1.44 MBs (3.5 inchs). The use and reliance on floppies has gone down considerably. Not like an internal hard drive, floppy drives can be detached. As they continue to be the medium most frequently employed to copy small files from one computer to another and to create rapid backups of important files, it is suggested that one acquires a floppy drive on any new system a user buys.

Video display: The computer video is comprised of a monitor and video card. As your monitor just displays what the video card has sent to it, the two parts should be compatible to receive the optimum video display expected. A lot of the latest motherboards possess the video card that is built in. It is ideal to get at least 17-inch monitor so as to take total benefit of the Windows environment. Frequently, a monitor larger than 17 inches is superfluous until one is making sketches and performing graphic works on the computer. It has to ensure that the video card and monitor mishmash can display a minimum of 256 colors, 16-bit or bigger is the ideal one. A majority of the multimedia programs will not executed unless the video card is able to display a minimum of 256 colors, 16 bit or greater. A lot of multimedia programs will not function until the video card can display a minimum of 256 colors. The usual video card which is not built into the motherboard currently displays in excess of million colors and able to be plugged into a PCI or AGP slot in the motherboard. It is always better to get a video card which has AGP.
