There are so many different types of computer networks in existence, it can be hard to understand the differences between them, particularly the ones with very similar-sounding names. Computer networks can be characterized by their size as well as their purpose.
The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe.
Some of the different networks based on size are:
Local area network, or LAN
Metropolitan area network, or MAN
Wide area network, or WAN
This WebQuest will explain the structures and functions of some of the most popular computer networks.
