Read Only Memory
2010-09-27 16:59:05

Read only memory, or ROM, is a type of storage media that is used by computers and other electronic devices. The data stored in ROM cannot be modified, therefore it is largely used to distribute firmware. The most straightforward type of ROM is about as old as semiconductor technology. It is called mask ROM, and it was introduced along with the integrated circuit. Mask ROM is made up of a grid...

Random Access Memory
2010-09-27 16:50:16

Random access memory (RAM) is a form of computer data storage that takes the form of integrated circuits in order to allow stored data to be accessed in any order. Random refers to the idea that any piece of data can be restored in a constant time, regardless of its physical location and whether or not it is related to the prior piece of data. The word RAM is often associated with unstable...

RAID

RAID is an acronym that stands for "redundant array of independent disks". It is a technology that is geared to provide greater storage reliability by combining numerous low-cost, less-reliable disk drive components into a reasonable unit where all drives are interdependent. Historically, RAID was first seen by Norman Ken Ouchi, when in 1978 he was awarded a U.S. patent called "System for...

Personal Computer

A personal computer, or PC, refers to any general-purpose computer whose size, capabilities, and selling price make it useful for individuals, and is intended to be managed directly by a user with no superseding operator. Examples of personal computers include desktop computers, laptops, tablet PCs, and handheld PCs. Most commonly, PCs are used in a home or office setting. Historically, the...

Network

A network is a group of computers and devices that are interconnected by communications channels. These channels facilitate communications among users and allow them to share resources. Many different characteristics can be used to classify a network. There are several purposes for networks. One of the most common uses of a network is for communication purposes. With a network, people can...

Motherboard
2010-09-13 13:36:36

A motherboard is the central printed circuit board in most modern computers and holds many of the vital components of the system as well as provides connectors for other peripherals. Before the microprocessor was introduced, computers were usually made in a card-cage case or mainframe with the gears connected by a backplane that consisted of a set of slots connected with wires. In much older...

Memory
2010-09-13 12:44:42

In computing, memory applies to the state information of a computing system because it is kept active in some physical structure. The term "memory" is used for the fast information in physical systems, as a distinction from physical systems which are slow to access. The term also refers to temporary state devices. Informally, computer memory refers to the physical devices used to store data or...

Mouse
2010-09-13 11:21:26

In relation to computing, a mouse is a pointing device that operates by detecting two-dimensional motion that is relative to the surface that supports it. Typically a mouse is an object held under the user's hand. It may have one or more buttons or wheels which allow the user to perform operations or other features that provide more control or dimensional input. The mouse's motion generally...

Keyboard
2010-09-10 14:54:21

A keyboard is an arrangement of buttons or keys that act as mechanical levers or electronic switches to input data into computers. Despite the development of alternative input devices, the keyboard is still the most commonly used and most versatile device used for direct input into computers. A keyboard typically has letters, numbers, and signs printed on the keys. Each press of a key...

Input-Output
2010-09-10 14:35:45

Input/output, commonly known as I/O, is the communication that goes on between a information processing system and the outside world, which may be a person or another information processing system. The signals and data received by the system are known as inputs, and the signals and data sent from the system are known as outputs. I/O can also refer to an action as well. An input or output...
