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. This is 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 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.
COM Port
Abbreviation for communication port. This is your serial interface connection.
Command
An instruction which you give your operating system. Example: run a pa rticular 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.
