binary - Computer Definition
See binary notation.
Meaning two. The principle behind digital computers. All input to the computer is converted into binary numbers made up of the two digits 0 and 1 (bits). For example, when you press the "A" key on your keyboard, the keyboard circuit generates and transfers the number 01000001 to the computer's memory as a series of pulses with different voltages. The bits are stored as charged and uncharged memory cells or as microscopic magnets on disk and tape. Display screens and printers convert the binary numbers into visual characters. Circuits Are Binary The electronic circuits that process these binary numbers are also binary in concept. They are made up of on/off switches (transistors) that are electrically opened and closed. The current flowing through one switch turns on (or off) another switch, and so on. These switches open and close in nanoseconds and picoseconds (billionths and trillionths of a second). See Boolean logic. Smaller Spots - Faster Switches A computer's capability to do work is based on its workspace capacity (memory), storage capacity (disk) and the speed of its circuits. Greater memory and disk capacities are achieved by making the memory cell or magnetic spot smaller. Faster circuit speeds are achieved by shortening the time it takes to open and close the transistor (electronic switch). In order to increase computer performance, we keep improving binary technologies. See binary numbers, binary values, binary file, binary standard and binaries.
