5. LAN uses Guided Media

MAN

1. MAN ((Metropolitan Area Network) is a larger network of computers and other network devices which are connected together usually spans serveral buildings or large geographical area.
2. All the devices that are part of MAN are span across buildings or small town.
3. MAN network has lower speed compared to LAN.
4. MAN connection speeds can be 10Mbps or 100Mbps.
5. MAN uses Guided Media or Unguided media.

WAN

1. WAN (Wide Area Network) is a group of computers and other network devices which are connected together which is not restricted to a geographical location. Internet is WAN
2. All the devices that are part of WAN have no geographical boundaries.
3. WAN speed varies based on geographical location of the servers. WAN connects serveral LANs
4. WAN connection speeds can be 10Mbps or 100Mbps.
5. WAN mainly uses Guided Media or Unguided media. Its long distance communications, which may or may not be provided by public packet network.
