Session 29 (14 June 2012)

- There are three types of network, which are LAN (Local Area Network), WAN (Wide Area Network) and MAN (Metropolitan Area Network).

- LAN covers a small region of space.


- MAN is a collection of LANs with the same geographical area.


- WAN is a collection of LANs or MANs or the mix of two with a very large geographical area.


- Setting up MAN is more expensive than LAN but less than WAN.


- LAN covers only a limited area, MAN covers a greater area, and WAN covers the largest geographical area.


- LAN offers the best speed, followed by MAN and WAN.


- LAN uses the cheapest transmission media.
