Introduction

For the computers to be able to communicate they must establish a language in which to communicate . A protocol is a set of rules which are used to govern how computers communicate with each other . In this an analysis is done to establish the best protocol to use when interconnecting computers for a company not centrally located

Local Area Network

The most suitable networking protocol for the Local Area Network is Ethernet . Ethernet is a protocol that uses

coaxial wires to transfer data from one computer to the other at the rate of 10Mbps (Kelvin 1999

Advantages

The cable used in an Ethernet Network is shielded well and has very high immunity from electrical noises

It simple to install and configure than most of the other network protocols

It is more compliant to the backbone connection unlike the other LAN protocols

It is cheaper to upgrade as its super fast networks are based on affordable technologies

Wide Area Network

The most suitable networking protocol for Wide Area Network would be the ATM which stands for Asynchronous Transfer Mode (Andrew 2003 . It composes a protocol suite which establishes a mechanism whereby it carries signals in fixed 53 byte packets . It is a connection-oriented technology

Advantages

Very high speeds Mbps or even at times Gbps

Efficient usage of the Bandwidth by the statistical multiplexing

Has the capability to use all the common physical transmission paths

Can use either the...
