ETHERNET:
This is the most widely used form of LAN transmission. (IEEE 802.3
standard). It is based on a BUS TOPOLOGY and runs over twisted pair, co-
ax or fibre-optics.
There are a number of variants to ETHERNET, common ones are:
nn BASE x , where nn is the speed, in, Mbits/s and x is the medium used e.g.
T for Un-Shielded twisted pair or F for Fibre-Optic etc. Therefore, 100 BASE
F network would indicate a 100Mbits/s transimission using Fibre-Optic cable.

FIBRE-OPTICS:
A medium to transmit encoded digital data as pulses of light.
FILE SERVER:
A computer connected to a network, which runs the operating system and
contains the shared files that are to be accessed by members of the

FRONT END:

application, that requests service from the 'server' or 'BACK END'. Now, it
is more often used to describe the user interface of an application or
service.
GATEWAY:
