A computer network allows sharing of resources and information among
devices  connected to the network. The Advanced Research Projects
Agency (ARPA) funded the design of the Advanced Research Projects
Agency Network (ARPANET) for the  United States Department of
Defense. It was the first operational computer  network in the world.
Development of the  network began in 1969, based on designs developed
during the 1960s.  
  
Purpose:
Computer networks can be used for several purposes:

• Facilitating communications. Using a network, people can communicate  efficiently and easily via e-mail, instant messaging, chat rooms, telephone,  video telephone calls, and video conferencing.
• Sharing hardware. In a networked environment, each computer on a  network can access and use hardware on the network. Suppose several personal  computers on a network each require the use of a laser printer. If the personal  computers and a laser printer are connected to a network, each user can then  access the laser printer on the network, as they need it.
• Sharing files, data, and information. In a network environment, any  authorized user can access data and information stored on other computers on the  network. The capability of providing access to data and information on shared  storage devices is an important feature of many networks.
• Sharing software. Users connected to a network can access application programes on the  network.
