Types of Computer Networks

There are many different types of computer networks and some of them are stated below:

  • Local Area Network (LAN)

LAN is one of the simplest types of computer networks in which computers are connected together over the span of small distances. This type of network is perfect for sharing resources like printers or data storage.

  • Personal Area Network (PAN)

In a personal area network, there is an interconnection of information technology that organized around an individual person typically within a range of 10 meters. This type of computer network can also be interconnected without any need for wires to the internet.

  • Wide Area Network (WAN)

A WAN is a complex type of computer network that connects the computer together over larger distances. It allows them to have communication no matter how far they are from each other. One of the best examples of a WAN is internet through computers can connect all around the world.

  • Metropolitan Area Network (MAN)

There is an involvement of a computer network that spreads across the whole city in the metropolitan area network. It is bigger than a LAN and covers an area that can range from many miles to ten miles. The major use of the MAN is to connect many LANs together for forming a larger network.

Advantages of Computer Networks

Here are some advantages of computer networks you need to aware about:

  • More Convenient Resource Sharing
