Network Types

There are 3 kinds of Networks / Network are:
a. Local Area Network (LAN) / Local Area Network.

A LAN is a network that is limited by a relatively small area, generally bounded by the area like an office environment in a building, or a school, and usually not far from about 1 km square. Several models of LAN configuration, one computer is usually made in a file server. Which is used to store software (software) that regulate network activity, or as software that can be used by komputerkomputer that is connected to the network. The computers are connected to the network (network) is usually called a workstation. Usually workstation capabilities over the bottom of the file server and have other applications on the hard drive in addition to applications for the network. Most LANs use the media cable for connecting between one computer to another computer.

b. Metropolitan Area Network (MAN) / Metropolitan area network



A MAN, usually covering a larger area than a LAN, for example between regions within a province. In this case the network connecting several small networks into larger areas of environment, for example as follows: Bank network in which several branches of a bank in a big city is connected between each other. For example, Bank BNI in the entire region or Surabaya Ujung Pandang.

c. Wide Area Network (WAN) / Large Scale area network


Wide Area Networks (WAN) is a network that already use a scope usually means satellite or submarine cable as an example of the whole network BANK BNI in Indonesia or in other countries. Using the WAN facilities, a bank in Bandung can contact its branch offices in Hong Kong, just a few minutes. WAN usually rather complicated and very complex, using many means to connect between LAN and WAN to the Global Communications such as the Internet. But somehow between LAN, MAN and WAN are not much different in some respects, only the scope of the area is just a different one among others.
