Types of Computer Networks
There are mainly five types of Computer Networks
Types of Computer Networks
These are explained below.
1. Personal Area Network (PAN)
PAN is the most basic type of computer network. This network is restrained to a single person, that is, communication between the computer devices is centered only on an individual’s workspace. PAN offers a network range of 1 to 100 meters from person to device providing communication. Its transmission speed is very high with very easy maintenance and very low cost.
Examples of PAN are USB, computer, phone, tablet, printer, PDA, etc.
Personal Area Network (PAN)
2. Local Area Network (LAN)
LAN is the most frequently used network. A LAN is a computer network that connects computers through a common communication path, contained within a limited area, that is, locally. A LAN encompasses two or more computers connected over a server. The two important technologies involved in this network are Ethernet and Wi-fi. It ranges up to 2km & transmission speed is very high with easy maintenance and low cost.
Examples of LAN are networking in a home, school, library, laboratory, college, office, etc.
Local Area Network (LAN)
3. Campus Area Network (CAN)
CAN is bigger than a LAN but smaller than a MAN. This is a type of computer network that is usually used in places like a school or colleges. This network covers a limited geographical area that is, it spreads across several buildings within the campus. CAN mainly use Ethernet technology with a range from 1km to 5km.
Its transmission speed is very high with a moderate maintenance cost and moderate cost.
Examples of CAN are networks that cover schools, colleges, buildings, etc.

4. Metropolitan Area Network (MAN)
A MAN is larger than a LAN but smaller than a WAN. This is the type of computer network that connects computers over a geographical distance through a shared communication path over a city, town, or metropolitan area. This network mainly uses FDDI, CDDI, and ATM as the technology with a range from 5km to 50km. Its transmission speed is average. It is difficult to maintain and it comes with a high cost.
Examples of MAN are networking in towns, cities, a single large city, a large area within multiple buildings, etc.

5. Wide Area Network (WAN)
WAN is a type of computer network that connects computers over a large geographical distance through a shared communication path. It is not restrained to a single location but extends over many locations. WAN can also be defined as a group of local area networks that communicate with each other with a range above 50km.
Here we use Leased-Line & Dial-up technology. Its transmission speed is very low and it comes with very high maintenance and very high cost.
The most common example of WAN is the Internet.

Types of Computer Networks
Pre-Requisite: Computer Networking
A computer network is a cluster of computers over a shared communication path that works to share resources from one computer to another, provided by or located on the network nodes.
