There are types of Network.

Types of Network

There are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose.

1. LAN - Local Area Network   
2. WAN - Wide Area Network
3. MAN - Metropolitan Area Network
4. PAN - Personal Area Network
5. SAN  - Storage Area Network
6. EPN - Enterprise Private Network
7. VPN - Virtual Private Network

LAN - Local Area Network

↪A local area network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, such as data storage and printers. LANs can be built with relatively inexpensive hardware, such as hubs, network adapters and Ethernet cables.

↪The smallest LAN may only use two computers, while larger LANs can accommodate thousands of computers. A LAN typically relies mostly on wired connections for increased speed and security, but wireless connections can also be part of a LAN.

WAN - Wide Area Network

↪A wide area network, or WAN, occupies a very large area, such as an entire country or the entire world. A WAN can contain multiple smaller networks, such as LANs or MANs. The Internet is the best-known example of a public WAN.

MAN - Metropolitan  Area Network
↪A metropolitan area network, or MAN, consists of a computer network across an entire city, college campus or small region. A MAN is larger than a LAN, which is typically limited to a single building or site. Depending on the configuration, this type of network can cover an area from several miles to tens of miles.
↪A MAN is often used to connect several LANs together to form a bigger network. When this type of network is specifically designed for a college campus, it is sometimes referred to as a campus area network, or CAN.
