What is a Computer Network?

Computer Network is a group of computers connected with each other through wires or wireless so that various devices can interact with each other through a network. The aim of the computer network is the sharing of resources among various devices.

Features Of Computer network –

– Communication speed

-Software and Hardware sharing

-File sharing

-Security

-Scalability

-Reliability

Communication speed

Network provides us to communicate over the network in a fast and efficient manner. For example, we can do video conferencing, email messaging, etc. over the internet. Therefore, the computer network is a great way to share our knowledge and ideas.

Software and Hardware sharing

We can install the applications on the main server, therefore, the user can access the applications centrally. So, we do not need to install the software on every machine. Similarly, hardware can also be shared.

File sharing

File sharing is one of the major advantage of the computer network. Computer network provides us to share the files with each other.

Security

Network allows the security by ensuring that the user has the right to access the certain files and applications.

Scalability

Scalability means that we can add the new components on the network. Network must be scalable so that we can extend the network by adding new devices. But, it decreases the speed of the connection and data of the transmission speed also decreases, this increases the chances of error occurring. This problem can be overcome by using the routing or switching devices.

Reliability

Computer network can use the alternative source for the data communication in case of any hardware failure.
