Silicon Chip: Microscopic pieces that make up the CPU. [|Hard Drive]**:** a hard drive is a [|non-volatile storage] device which stores digitally encoded data on rapidly rotating [|platters] with [|magnetic] surfaces.
 * [|System Unit]:** The main part of a computer that is held together by a plastic or metal enclosure. It holds the mother board, and any circutry attached to the mother board, cooling fans, disk drive, and a power supply.
 * [|CPU]:** Central Processing Unit, the "Brain" of the computer, It controls everything that the computer does.
 * [|Hertz]:** the SI unit of frequency, equal to one cycle per second
 * [|RAM]:** Random-Access Memory, Stores information that the computer (at that time) is holding.
 * [|ROM]:** Read-Only Memory, Holds data information for the computer that does not change.
 * [|Bit]****:** A type of mesurement that works in the [|Binary Numerical System].
 * [|Byte]**: In [|computer science] a **byte** is a ubiquitous unit of [|storage] measurement. It is also one of the basic [|integral data types] in many [|programming languages]. (1 byte = 1 character)
 * [|Kilobyte]:** 1024 (210) bytes/ 1000 bytes
 * [|Megabyte]:** 220 (1,048,576) bytes/ one million bytes
 * [|Gigabyte]:** a measure of storage capacity equal to 1 billion (109) bytes
 * [|Storage Devices]:** A hardware device, such as a hard disk or floppy disk, used to record and store data
 * [|Medumm/Media]:** one of the means or channels of general communication, information, or entertainment in society
 * [|Input Devices]:** A device, such as a keyboard, used to enter information into a computer
 * [|Output Devices]:** A device, such as a printer, video display, or speaker, that presents data from a computer to a user
 * [|Resolution]:** the degree of sharpness of a computer-generated image as measured by the number of dots per linear inch in a hard-copy printout or the number of pixels across and down on a display screen.
 * [|Pixels]:** The basic unit of the composition of an image on a television screen, computer monitor, or similar display
 * [|Peripheral Devices]:** any device attached to a computer in order to expand its functionality
