1. List the Basic essential components of a computer network

Ans 1: The essential components of a Computer network are listed below:

Ø 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.

Ø Nodes:

Nodes are the computers on the network, which are provided to the users to carry out their tasks using the network.

Ø Workstation:

A node, which is more powerful, and can handle local information processing or graphics processing is calls a workstation. The workstation works only for the person sitting in front of it, where as a server serves all the people on the network to share its resources.

Ø 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.

Ø LAN Software:

LAN cables connect all the nodes and servers together to form the network. In addition to its local disk operating system, each node requires networking software that enables the nodes to communicate with the servers. In file servers run network software that communicates with the nodes.

Ø LAN Cable:

This is the medium or channel over which the information travels from computer to computer. The information travels from one computer onto the medium and then from the medium to another computer in the form that it can be read.

Ø Network Interface Card:

Each computer contains a network interface card. This card is used to connect the cables to the computers. These cards help the computer to transfer the data at a faster rate and in the form of packets. These cards are plugged into the computer motherboard. These cards are generally called as Ethernet cards.
