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.
