All Types of Networks – Fully Explained

Hey, in this article we will discuss about various types of Networks. Internet, is the widest network and today it is need for every types of business. In the following session, we will cover various types of Networks. Although, We know you might heard many types of networks given below, but this article will guide you in a best way.


Types of Networks

1. Personal Area Network (PAN)

A personal Area Network(PAN), is an types of networks, which is used to transmit data among personal devices such as Computer, smartphones, Modem etc.. Such devices, connected with Bluetooth, USB etc.

2. Local Area Network (LAN)

Local Area Network (LAN), is one of the famous types of networks, which is used in Enterprise Network, Campuses, Organisations, Schools, Labs and many more places. There is several Workstations, Computers or Laptop, are present in a LAN, which share data with one another devices. All these devices are interconnected with the help of Network Switches. With the help of WAN devices like Routers and Firewalls, computers in a LAN can communicate with other LAN. For internet connectivity, We usually use NAT (Network Address Translation) on a Firewall or Router.

3. Campus Area Network (CAN)

Campus Area Network (CAN), is larger than a LAN and smaller than MAN and WAN (Described Below). A Campus area is an types of networks, which covers network of a campuses like Universities, Colleges. Here, various LAN’s are interconnected with Layer 3 devices like Router or Multi-Layer Switch within a limited Geographic Area. Whenever we needs to provide Internet connectivity, we need to connect it with Lease Lines using NAT(Network Address Translation). This is also known as Corporate Area Network (CAN).

4. Metropolitan Area Network(MAN)

Metropolitan area network is a computer network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large Local Area Network but smaller than the area covered by a Wide Area Network.

5. Wide Area Network (WAN)

Wide Area Network, is biggest computer network, which covers Large Geographical Area. WAN usually use Leased Lines to connects different Geographical locations.

Internet is the main basis example of Wide Area Network. Any computer in any geographic area, can communicate with the help of WAN. WAN, usually used to connect different countries. There is millions of LAN’s in Wide Area Network.

Some Other Types of Networks

Although, we have discussed all basis types of Network. But, still we have various types of networks, which is driven from basis types of network, but they are used in Industries. So, in below session, we will discuss, Storage Area Network (SAN), Virtual Private Network (VPN) and Wireless Local Area Network (W-LAN).

1. Storage Area Network (SAN)

According to Wikipedia, A storage area network or storage network is a Computer network which provides access to consolidated, block level data storage. It is a high speed computer network, which have block-level access to large data storage.

2. Virtual Private Network (VPN)

Virtual Private Network, as name suggest, is a highly encrypted secure connection, over a non-secure network. This technology used by many organisations for different purposes. For Example, with the help of VPN their employee can work from home. They usually use, IPSec (IP Security) VPN, also known as Site to Site VPN.

3. Wireless Local Area Network (W-LAN)

I know you are familiar with this types of networks – Wireless Local Area Network (W-LAN), is a Local Area Network or Wireless Computer Network, where devices are interconnected without a Ethernet (wired) connection. Here, two or more computers are interconnected in such a way so that they can transmit data over a wireless connection. All the devices are interconnected with the help of Wi-Fi technology. Here, for the interconnection, a Access Point (AP’s) use in replacement of network switch.


In this article, we discuss about various types of networks. Here, we discussed, Personal Area Network (PAN), Local Area Network (LAN), Campus Area Network (CAN), Metropolitan Area Network (MAN) and Wide Area Network (WAN). After that we discussed some networks which are made with the help of basis network types. We also discussed, about VPN and importance of VPN.
