Easy Sharing Software
Through the networking system, it is easy to share and install the software from one computer system to another computer system.

Easy to Decentralize Data Processing

  • Metropolitan Area Network (MAN)
  • Wide Area Network (WAN)

Local Area Network
Local Area Network or simply LAN is the technique of interconnecting a few computers located in a given premise. It is normally used for a single business office or a residential apartment.
The major purpose of such interconnectivity is to establish a communication system in order to make the work easier.
However, in such connectivity, some other devices can also be attached such as laser printers, fax machine, etc.

Metropolitan Area Network
Metropolitan Area Network or simply MAN is a system of network that normally covers a large metropolitan area (city part).
It provides high speed Internet services throughout the area covered within the network.

Wide Area Network
Wide Area Network or simply WAN is a system of network that covers a large geographical area across the world.
The services of WAN are provided by public (government) agencies as well as private agencies.
The network also provides the facility to access databases located remotely.
The WAN system is highly beneficial for MNCs and other big corporate companies (offering online services).
