TYPES OF NETWORKS

• Personal area network-PAN

This is a computer network organised around a person. Personal area networks typically involve a mobile computer, a cell phone and/or a handheld computing device such as a PDA. You can use these networks to transfer files including email and calendar appointments, digital photos and music.

• Local area network(LAN)

A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as a home, school, computer laboratory, office building, or closely positioned group of buildings. Each computer or device on the network is a node.

• Metropolitan area network(MAN)

A metropolitan area network (MAN) is a large computer network that usually spans a city or a large campus.

• Wide area network(WAN)

A wide area network (WAN) is a computer network that covers a large geographic area such as a city, or country, or spans even intercontinental distances, using a communications channel that combines many types of media such as telephone lines, cables, and airwaves. A WAN often uses transmission facilities provided by common carriers, such as telephone companies.

• Client-Server Network

Client-server network is designed for end-users, called clients, to access resources such as files, songs, video collections, or some other service from a central computer called a server.

• Peer-To-Peer (P2p) Network

In its simplest form, a peer-to-peer (P2P) network is created when two or more PCs are connected and share resources without going through a separate server computer. A P2P network can be an ad hoc connection—a couple of computers connected via a Universal Serial Bus to transfer files.
