Various Computer Networks

  • Local Area Networks (LANs): In LANs, the computers are located quite close to the geographical point of view. These can be in the same building. For example, factories, offices and certain groups of buildings keep and use this kind of network. LANs are private networks and carry a good amount of speed when compared with that of the WAN.

So these can be used by all those devices in that town or city that have a connection of this network. MAN is a bigger and better version of LAN only and makes use of the same technology as that of the LAN.
  • Campus Area Networks (CANs): This refers to the network within a campus or some military area. Again the geographic distance is much less among the systems. A CAN actually is a network of networks. It is smaller than MAN and WAN but is a network of multiple interconnected local area networks or LAN.
  • Home Area Networks (Hans): Home area networks refer to the networks within a person’s house. This one connects the devices present in the house. A small area is what is under the network coverage of HAN. So small offices and homes come under this category.
