INTRODUCTION TO NETWORKING
A network is a system that transmits any combination of voice, video and/or data between users. A network can be defined by its geographical dimensions and by which the user’s PC access it.
A network consists of a:
• The network operating system (Windows NT/2000TM/Xp) on the user’s PC (client) and server. • The cables connecting all network devices (user’s PC, server, peripherals, etc.). • All supporting network components (hubs, routers and switches, etc.). Computer Network means an interconnected collection of autonomous computers.
Requirement of Networking
Resource sharing- To make all programs, equipment, and especially data available to anyone on the network without regard to the physical location of the resource and the user.
High reliability- As all files could be replicated on two or three machines, so if one of them is unavailable (due to hardware failure), the other copies could be used.
Scalability- It is the ability to increase system performance gradually as the workload grows just by adding more processors. A computer network can provide a powerful communication medium along widely separated employees.
The use of networks to enhance human-to-human communication will probably prove more important than technical goals such as improved reliability.
These are the requirement with respect to companies but computer networking is required even in the normal day to day life as we have to access the internet to get information about what all new happening in the world, to have communication with people staying far away using the e mail service.
These are the reasons that forced the inventerors to invent the networking devices, models and protocols etc.
And the birth of Networking took place in 1844 when for the first time Samuel Morse send the first telegraph message. TYPES OF NETWORKS
LAN (LOCAL AREA NETWORK)
These are privately owned networks within a single building or campus of up to a few a kilometers in size. LAN’s are distinguished from other networks by three characteristics: 1) Their size.
2) Their transmission technology.
3) Their topology.
LAN’s are restricted in size, which...
