DETERMINING VALUE OF COMPUTER
system, in the standard market place, is 1. Processor, speed and type, as well as branding or manufacturer, 2. Random Access Memory [RAM] on computer at point of sale, maximum RAM expansion allowable, as well as type memory, i.e. DDR1, DDR2, DDR3, etc, 3. Hard Disk Drive storage space . Other important methods for determining value, of home computer system, would be Monitor, Video card and Audio card, followed by media type [cd/dvd burner] keyboard, mouse, speakers and microphone. |
Manufacturers and retailers 'bundle' together components of computer systems, like tower or desktop, monitor, keyboard and mouse, sometime along with speakers, to enhance quick sales, but it is important to realize that each of these components may be purchased separately, though made by different manufacturers, to realize savings, so one should compare before buying and always realize that if you already have a component at home, whether HP, Dell, Gateway or someone else, then you can use that and do not have to purchase the entire system. |
UNDERSTANDING COMPUTER MEMORY
memory, standing for Double Data Rated, and it is available in three speeds, each progressively faster, DDR, 266Mhz-pc2100, 333Mhz-pc-2700, 400Mhz-pc-3200. Stndard DDR became DDR1 when manufacturing of DDR2, and DDR3 came along. The latter being even faster. We will post other size/speed memory shortly |

| Glossary of Terms PROCESSOR The central processing unit, CPU, or processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary ele- ment carrying out the functions of the computer or other processing device. It carries out each instruction of the program in sequence, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU is known as the "brains" of the computer, since the early 1960s. It is also known as a Microprocessor at least since the 1970. RAM Random-Access Memory is computer data storage in inte- grated circuits which allow stored data to be accessed in any order with a worst case performance of constant time. Strictly speaking, modern types of RAM are therefore not random access, as data is read in bursts though the term RAM continue to be used. RAM is often associated with volatile types of memory or memory modules, where its stored information is lost if the power is removed, though other types of non-volatile memory are RAM , including most types of ROM and a type of flash memory called NOR-Flash. ROM Read-Only Memory is a type storage used in computers and other electronic products, which can only be altered or changed by a professional and is primarily used to distribute software, firmware or computer programs normally associated with specific hardware which seldom need updates Hard Drive Hard Drive, hard disk drive, hard disk or HDD is a non-volatile, random access digital data storage unit, having rotating, rigid, platters, outwardly similar in 'appearance' to CD/DVD disks, on a motor-driven spindle inside a protective cover on which data is magnetically read from and written to the platter by read/write heads that float on a film of air above the platters. It is some time called the "brain" of the computer Video Card , A video card, video adapter, graphics accelerator card, display adapter, or graphics card is an expansion card which generates output images to a display sometime integrated into the motherboard. Sound Card A sound card /audio card is an internal computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. The term sound card is also applied to external audio interfaces that use software to generate sound, as opposed to using hardware inside the PC. It can produce 3-D audio for games or surround sound playback for DVDs. It can also capture and record sound from external sources. |

| What is a computer virus? A computer virus is a small software program that spreads from one computer to another computer and that interferes with computer operation. A computer virus may corrupt or delete data on a computer, use an e-mail program to spread the virus to other computers, or even delete everything on the hard disk. Computer viruses are most easily spread by attachments in e-mail messages or by instant messaging messages. Therefore, you must never open an e-mail attachment unless you know who sent the message or unless you are expecting the e-mail attachment. Computer viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread by using downloads on the Internet. Computer viruses can be hidden in pirated software or in other files or programs that you may download. Symptoms that may be the result of ordinary Windows functions A computer virus infection may cause the following problems: Note: These problems may also occur because of ordinary Windows functions or problems in Windows that are not caused by a computer virus. Windows does not start even though you have not made any system changes or even though you have not installed or removed any programs. Windows does not start because certain important system files are missing. Additionally, you receive an error message that lists the missing files. The computer sometimes starts as expected. However, at other times, the computer stops responding before the desktop icons and the taskbar appear. The computer runs very slowly. Additionally, the computer takes longer than expected to start. You receive out-of-memory error messages even though the computer has sufficient RAM. New programs are installed incorrectly. Windows spontaneously restarts unexpectedly. Programs that used to run stop responding frequently. Even if you remove and reinstall the programs, the issue continues to occur. A disk utility such as Scandisk reports multiple serious disk errors. A partition disappears. The computer always stops responding when you try to use Microsoft Office products. You cannot start Windows Task Manager. Antivirus software indicates that a computer virus is present. Symptoms of a computer virus If you suspect or confirm that your computer is infected with a computer virus, obtain the current antivirus software. The following are some primary indicators that a computer may be infected: The computer runs slower than usual. The computer stops responding, or it locks up frequently. The computer crashes, and then it restarts every few minutes. The computer restarts on its own. Additionally, the computer does not run as usual. Applications on the computer do not work correctly. Disks or disk drives are inaccessible. You cannot print items correctly. You see unusual error messages. You see distorted menus and dialog boxes. There is a double extension on an attachment that you recently opened, such as a .jpg, .vbs, .gif, or .exe. extension. An antivirus program is disabled for no reason. Additionally, the antivirus program cannot be restarted. An antivirus program cannot be installed on the computer, or the antivirus program will not run. New icons appear on the desktop that you did not put there, or the icons are not associated with any recently installed programs. Strange sounds or music plays from the speakers unexpectedly. A program disappears from the computer even though you did not intentionally remove the program. Note These are common signs of infection. However, these signs may also be caused by hardware or software problems that have nothing to do with a computer virus. Unless you run the Microsoft Malicious Software Removal Tool, and then you install industry-standard, up-to-date antivirus software on your computer, you cannot be certain whether a computer is infected with a computer virus or not. Back to the top Symptoms of worms and trojan horse viruses in e-mail messages When a computer virus infects e-mail messages or infects other files on a computer, you may notice the following symptoms: The infected file may make copies of itself. This behavior may use up all the free space on the hard disk. A copy of the infected file may be sent to all the addresses in an e-mail address list. The computer virus may reformat the hard disk. This behavior will delete files and programs. The computer virus may install hidden programs, such as pirated software. This pirated software may then be distributed and sold from the computer. The computer virus may reduce security. This could enable intruders to remotely access the computer or the network. You receive an e-mail message that has a strange attachment. When you open the attachment, dialog boxes appear, or a sudden degradation in system performance occurs. Someone tells you that they have recently received e-mail messages from you that contained attached files that you did not send. The files that are attached to the e-mail messages have extensions such as .exe, .bat, .scr, and .vbs extensions. [continue] |

| Motherboard is the central printed circuit board in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board. |
| In the modern Desktop computer most of the components displayed here will be housed within the body of the desktop. In a computer with tower they will be in the tower, and the same holds true for the laptop;these combined are called a computer. Auxilliary features such as keyboard, mouse, monitor, speakers, in combination with the aforementioned contents, make up the computer system, especially when complimented by a printer. |
