Some of the different networks based on their main purpose are: Let's look at each of these in a bit more detail. A Local Area Network (LAN) is a network that is confined to a relatively small area. The term MAN is applied to the interconnection of local area networks in a city into a single larger network which may then also offer efficient connection to a wide area network. Example of a Switched WAN is the asynchronous transfer mode (ATM) network and Point-to-Point WAN is dial-up line that connects a home computer to the Internet. When this type of network is specifically designed for a college campus, it is sometimes referred to as a campus area network, or CAN.

A LAN is a form of local (limited-distance), shared packet network for computer communications. Notes. The Network allows computers to connect and communicate with different computers via any medium. LANs are typically used for single sites where people need to share resources among themselves but not with the rest of the outside world. If the hosts are connected point-to-point logically, then may have multiple intermediate devices. Most computer networks are general purpose networks used for many different forms of communication, but some networks have been built for a very specific purpose. On a ‘Local Area Network’ data transfer speeds are higher than WAN and MAN that can extend to a 10.0 Mbps (Ethernet network) and 1.0 Gbps (Gigabit Ethernet). One of the benefits of networks like PAN and LAN is that they can be kept entirely private by restricting some communications to the connections within the network.
