Common Types of Computer Networks

Computer network design can range from simple to very complex. Networking can be as simple as connecting two computers, or a computer and a printer, while more complex networks can involve the connection of millions of computers and devices. Below is a brief outline of different computer network types.

Personal Area Network (PAN)

The smallest type of network, a PAN simply involves connecting one person's computer to a number of devices or peripherals. Usually, all devices, such as printers, PDAs, and telephones, are within a few feet of the computer. A PAN can also refer to a connection to the internet.

Local Area Network (LAN)

If you have a home network with two or more computers or you are connected to other computers at your workplace, then you are on a LAN. LANs are ideal for networking in a small geographical area and can either work with cables and hubs, or wirelessly. They allow for the speedy transfer of data—up to 10Gbit/s. Most LANs are based on Ethernet technology. Wireless Local Area Networks are known as WLANs.
