A network is a group of at least two computers linked together. Computer networks are found in different types. These networks can be established through many ways such as cables, radio waves, telephone lines, infrared light beams and satellites.
Local area networks. (LANs)
This is a computer network where the computers are in the same room. With this type of network, the connected computers are known as servers or workstations. Services provided by these networks are mainly printing and faxing, file storage and sharing, data storage and retrieval and many others. Click here to understand further.
Wide area networks. (WANs)
This is among the many computer networks where the computers are far apart. They are therefore connected by radio waves and telephone lines. The largest WAN that is in existence is actually the internet. Most users do not get the difference between a LAN and WAN since they look similar to users.

Personal area network
This is a computer network set up used by an individual in a single building. This is mainly found in an office or residential area.

In this case a single internet connection is used then it is managed using a single computer but accessed by many devices.
