Basic Essential of Computer Network
The computer is one of the most important inventions of the past century. We know how to use it, but little do we know about what is inside to connect with the internet.
Component of Computer Network:
The essential components of a simple network are listed below:-
Servers: Servers are faster computers that run various software’s, store and process information and also provide a human interface for the users to be able to use the networked computers.
Nodes: Nodes are the computers on the network, which are provided to the users to carry out their tasks using the network.
Workstation: A node, which is more powerful, and can handle local information processing or graphics processing is called a workstation. The workstation works only for the person sitting in front of it, whereas a server serves all the people on the network to share its resources.
A workstation usually has an inexpensive, small hard disk to carry out local tasks. Some workstations, called disk-less workstations, have no disk drive of their own. Such workstations also called dumb terminals and they rely completely on the LAN for their access.
Network Operating System (NOS): The network requires some software to control all the information transfer activity on the network, like the traffic police to control the traffic. The software called NOS handles these tasks. Networks, which are more complex, require network devices like hubs, switches & routers to carry out different network function.
LAN Software: On the network, each computer is called a node or a workstation unless there are certain computers designed as servers.
LAN Cable: This is the medium or channel over which the information travels from computer to computer. The information travels from one computer to the medium and then from the medium to another computer in the form that it can be read.
