GLOSSARY

(AGP) - An Intel-developed interface that enables high-speed graphics. Graphics data move between the PC's graphics controller and computer memory directly, instead of being cached in video memory.

The average time (in nanoseconds) for RAM to complete one access. Access Time is composed of address setup time and latency (the time it takes to initiate a Request for data and prepare access).

The amount of data moved on electronic lines, such as a bus, per second. bandwidth is usually measured in bits per second, bytes per second, or cycles per Second (Hertz).

A numbering system that uses combinations of 0 and 1 to represent data. Also known as Base 2.

(Basic Input-Output System) - Startup routines that prepare the computer for operation.

The smallest unit of information a computer processes. A bit is 1 or 0.

A holding area for data shared by devices that operate at different speeds or have different priorities. A buffer allows a device to operate without the delays that other devices impose.

(BEDO) - EDO memory that can process four memory addresses in one burst. Bus speeds range from 50MHz to 66MHz (compared to 33MHz for EDO and 25MHz for Fast Page Mode).

A data path in a computer, consisting of various parallel wires to which the CPU, memory, and all input/output devices are connected.

A single transaction between main memory and the CPU.

Eight bits of information. The byte is the fundamental unit of computer processing; almost all specifications and measures of computer performance are in bytes or multiples thereof. See kilobytes and megabytes.

A small amount (normally less than 1MB) of high-speed memory residing on or close to the CPU. Cache memory supplies the processor with the most frequently requested data and instructions. Level 1 cache (primary cache) is the cache closest to the processor. Level 2 cache (secondary cache) is the cache second closest to the processor and is usually on the motherboard.

Microchips that support the CPU. The chipset usually contains several controllers that govern how information travels between the processor and other components.

(Central Processing Unit) - The computer chip that has primary responsibility for interpreting commands and running programs. The CPU is also known as the processor or microprocessor.

Information or raw facts that is entered into the computer. It also can be exported in different formats from programs as Excel, Word, and a calculator for mathematical data.

A process that puts all the bytes of each file together in one location. This reduces the time the computer spends locating files.
