Glossary board: A circuit board. An internal card containing electronic components, called chips, which perform a specific function or increase the capabilities of the system. boot disk: See system disk. boot: Short for bootstrap. A program that starts or restarts the computer. The program reads instructions from a storage device into the computer's memory. bootable disk: See system disk. bps: Bits per second. Typically used to describe the data transmission speed of a modem. buffer: The portion of the computer's memory where data is temporarily stored. Buffers often compensate for differences in the rate of flow from one device to another. bus: An interface for transmission of signals, data or electric power. byte: The representation of a single character. A sequence of eight bits treated as a single unit; also the smallest addressable unit within the system. C cache memory: A section of very fast memory in which frequently used information is duplicated for quick access. Accessing data from cache is faster than accessing it from the computer's main memory. See also L1 cache, L2 cache. capacity: The amount of data that can be stored on a magnetic storage device such as a floppy diskette or hard disk drive. It is usually described in terms of kilobytes (KB), where one KB = 1024 bytes, megabytes (MB), where one MB = 1024 KB and gigabytes (GB), where one GB = 1024 MB. CD: An individual compact disc. See also CD-ROM. CD-R: A Compact Disc-Recordable disc can be written once and read many times. See also CD-ROM. CD-ROM: A Compact Disc-Read Only Memory is a high capacity disc that can be read from but not written to. The CD-ROM drive uses a laser, rather than magnetic heads, to read data from the disc. CD-RW: A Compact Disc-ReWritable disc can be rewritten many times. See also CD-ROM. character: Any letter, number, punctuation mark, or symbol used by the computer. Also synonymous with byte. chassis: The frame containing the computer. chip: A small semiconductor containing computer logic and circuitry for processing, memory, input/output functions and controlling other chips. click: To press and release the pointing device's primary button without moving the pointing device. In the Windows operating system, this refers to the pointing device's left button, unless otherwise stated. See also double-click. User's Manual Glossary-4

Glossary-4
Glossary
board:
A circuit board. An internal card containing electronic components,
called chips, which perform a specific function or increase the
capabilities of the system.
boot disk:
See
system disk.
boot:
Short for bootstrap. A program that starts or restarts the computer.
The program reads instructions from a storage device into the
computer’s memory.
bootable disk:
See
system disk.
bps:
Bits per second. Typically used to describe the data transmission
speed of a modem.
buffer:
The portion of the computer’s memory where data is temporarily
stored. Buffers often compensate for differences in the rate of flow
from one device to another.
bus:
An interface for transmission of signals, data or electric power.
byte:
The representation of a single character. A sequence of eight bits
treated as a single unit; also the smallest addressable unit within the
system.
C
cache memory:
A section of very fast memory in which frequently used
information is duplicated for quick access. Accessing data from
cache is faster than accessing it from the computer's main memory.
See
also L1 cache, L2 cache.
capacity:
The amount of data that can be stored on a magnetic storage
device such as a floppy diskette or hard disk drive. It is usually
described in terms of kilobytes (KB), where one KB = 1024 bytes,
megabytes (MB), where one MB = 1024 KB and gigabytes (GB),
where one GB = 1024 MB.
CD:
An individual compact disc.
See
also CD-ROM.
CD-R:
A Compact Disc-Recordable disc can be written once and read
many times. See also CD-ROM.
CD-ROM:
A Compact Disc-Read Only Memory is a high capacity disc that
can be read from but not written to. The CD-ROM drive uses a laser,
rather than magnetic heads, to read data from the disc.
CD-RW:
A Compact Disc-ReWritable disc can be rewritten many times.
See
also CD-ROM.
character:
Any letter, number, punctuation mark, or symbol used by the
computer. Also synonymous with byte.
chassis:
The frame containing the computer.
chip:
A small semiconductor containing computer logic and circuitry for
processing, memory, input/output functions and controlling other
chips.
click:
To press and release the pointing device's primary button without
moving the pointing device. In the Windows operating system, this
refers to the pointing device's left button, unless otherwise stated.
See
also double-click.
