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.
CD-ROM
Compact disk read only memory. This is a form of data storage which is read optically with a laser
rather than a magnetic head. A CD-ROM can contain about 600 MB of data and is not subject to heads
crashing into the surface and destroying the data when there is a failure nor to wear from reading.
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.
CRT
Cathode Ray Tube. A display device which uses a beam of electronic particles striking a luminescent
screen. It produces a visual image by varying the position and intensity of the beam.
