This post is all about what is a computer network , and it's similar info like network basics , advantage of computer network , types of computer network , etc. that is very important to everyone . it's most useful for those students who are getting ready for the pc Networking study or Operator examination .

• What is Computer  Networking ?

-> A computer network is a communication system where a group of computers and other devices like printers are connected by cables and other hardware , the data is shared between the computers .

This concepts of connected computer sharing resources is called computer Networking.  

• Advantages of Computer Networking :-

Network allow efficient management of resources for example :-

1. Multiple user can share a single HQ printer, rather then having multiple possibility lower quality printer on individual printer.

2. Network helps keep information reliable and up-to-date and manage.  Centralized data storage system allows multiple users to access data from difference location.

MAN (Metropolitan Area Network ) :-

-> In between  LAN and WAN is the MAN (Metropolitan Area Network ) . a MAN is a network that covers the entire City, but usage LAN technologies . cable television network are good example of MAN . the MAN can Carry information in the form of computer  signals from one computer to another .
