The processor is the part of the computer which controls all the other parts. It consists of the control unit (fetches and decodes), arithmetic and logic unit (ALU) and the memory. GHz refers to the unit of frequency that measures the clock rate (rate in cycles per minute at which a computer performs its most basic operations such adding two numbers or transferring a value from one register to another) of modern processors. 256 MB PC 2100 DDR SDRAM This refers to the memory of the system. 256 Mb is 256 megabytes which is the size of the storage device or memory.

SDRAM is Synchronous Dynamic Random Access Memory) The term "synchronous" means that the clock rate of memory is exactly synchronized with the clock rate of the bus (connects functional components of computer). It is important to install memory that matches the bus speed of a system to prevent the slowing of data transfer or complete incompatibility with motherboard. DDR (double data rate) means this memory module is DDR capable. SDRAM memory is a product built upon the foundation of older memory Unlike SDRAM that supports one operation per computer clock cycle, DDR SDRAM memory can do two operations per clock cycle. 40 GB 7200 RPM ATA 133 This is the hard drive of the system which is used to read or write hard disks. 40 GB (gigabytes) refers to the amount of storage that hard drive has.

7200 Rpm is rotations per minute meaning the speed of the HDD. and ATA (advanced technology attachment) 133 is the interface standard on the hard drive. 52 x 52 x 24 CD-RW Stands for Compact disk rewritable known commonly as a CD burner it copies or rewrites compact discs, 52 x 52 x 24 refers to the speed at which the CD can be read. Microsoft Multimedia keyboard An input device that converts letters numbers and characters into electrical signals that are machine readable by the computers processor. Multimedia mean that the keyboard has many functions of computer-human interaction such as video, graphics voice but primarily text. Microsoft is the company that creates the products.

Microsoft Wheel optical Mouse The mouse is another input device. It is a device moved on your desktop and consequently manipulates a pointer on screen normally shaped like an arrow. With the mouse you can select move and change items onscreen. Wheel optical means that the mouse does not use the a ball to signal movement rather it scans the surface to make the signal. 15" (15"viewable) Flat panel Display Refers to the monitor or the screen on which information and graphics are displayed.

The screen is 15 inches and all 15 of the inches are the display area. Flat panel display means that the monitor is a flat screen. Built -In Speakers Means the speakers are attached to the monitor rather than being separate. The speakers allow for sound output. Microsoft Windows XP Home Pro Is the systems software. System software is any software required to support the production or execution of application programs but which is not specific to any particular application.

Anti Virus Security Software to help detect and prevent a computer from virus. A virus is a program that infects a computer by attaching itself to another program, and propagating itself when that program is executed. A computer can become infected by files downloaded over a network, or by the installation of new software or floppy disks that are infected with viruses.

Some viruses are only pranks, and perform harmless actions like displaying a screen with a joke message on it. Others can destroy files or wipe out a hard drive. MODEL ONE AMD athlon XP 2600+ 512 MB Dual channel 33 MHz 80 GB 7200 RPM ATA 133 52 x 52 x 24 CD-RW 16 x DVD Microsoft Wireless optical desktop 19" (18.0"viewable) Flat Digital CRT monitor Microsoft Windows XP Home Ed AMD athlon XP 2600+ This is the processor / CPU (Central processing unit), the branding being 'AMD' and the product being 'Athlon XP'. 512 MB Dual channel 33 MHz This refers to the memory of the system. Memory of the computer can be any device that can hold data in machine-readable format. 512 Mb is 512 megabytes which is the size of the storage device or memory.

Dual channel is similar to DDR (double data rate) random access memory that transfers data on both 0-1 and 1-0 clock (rate at which computer executes instructions.) transitions, theoretically being twice the data transfer rate of normal RAM 80 GB 7200 RPM ATA 133 This is the hard drive of the system which is used to read or write hard disks. 16 x DVD An optical device used for reading DVDs or Digital Video Discs. 16 x refers to the speed to which the DVD is read. Microsoft Wireless optical desktop This is the keyboard and the mouse from company, Microsoft, which uses optical technology and therefore needs no cables. The system keyboard is an input device that converts letters numbers and characters into electrical signals that are machine readable by the computers processor. The mouse is another input device.
