Computer Networks

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)

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. These two types of networks are commonly used in schools. You could visit this website to know more www.webopedia.com
