Glossary
The external frequency is the speed of the front side bus
(FSB) and specifies the speed at which the processor can
access the main memory (and the L2 cache, if present). The
speed of the FSB is governed by the motherboard.

defined command or process.
Icon

ISDN
Short for “Integrated Services Digital Network”. ISDN is a
digital telecommunications network that can be used for
normal telephone calls, remote data transmission, faxing and
other services such as video conferences. ISDN offers
significantly higher bandwidth than the standard analog
telephone network. ISDN is an international standard that
should be applied to all existing and future networks. An
ISDN line consists of two basic channels, each of which can
transmit 64 kbits, and a control channel operating at 16 kbits.
LAN
Short for “local area network”. Distinct from a WAN (wide
area network), which connects workstations and networks
separated by greater geographical distances. In this sense,
“local” refers to a common location, such as a company
facility or a room.
Network
A group of computers connected by various types of cables or
radio connections that share common resources such as data
and peripheral devices. A network often includes a special
computer (server) that only manages the common data, and
which is accessed by all other workstations. The two principle
kinds of networks are LANs, which are used within a single
location, and WANs, which are used for example by multiple
branches of an organization in different cities or countries.
