132 - Glossary

Byte

8 bits of parallel binary information.

Cache Memory

A block of memory built into the micro-processor which is much faster to access than your system RAM
and used in specially structured ways to make your overall data handling time faster.

CardBus

A faster, 32-bit version of the PC Card interface which offers performance similar to the 32-bit PCI
architecture.

CD-ROM

Compact disk read only memory. A form of digital data storage which is read optically with a laser rather
than a magnetic head. A typical CD-ROM can contain about 600MB of data and is not subject to heads
crashing into the surface and destroying the data when there is a failure.

Channel

Range of narrow-band frequencies used by the WLAN device to transmit data. IEEE802.11b/g - 11
channels, 22 MHz wide channels.

CMOS RAM

Complementary metal oxide semiconductor random access memory. This is a technology for
manufacturing random access memory which requires very low levels of power to operate.

Command

An instruction which you give your operating system. Example: run a particular application or format a
floppy disk.

Configuration

The combination of hardware and software that makes up your system and how it is allocated for use.
