Goals or Objective of Computer Network

The main goal of a computer network is to enable its users to share resources and to access these resources (i.e. hard disks, high quality expensive laser printer, modems, peripheral devices, licensed software, etc.), regardless of their physical locations. Physical locations may be a few feet or even thousands of miles apart, but users exchange data and programs in the same way. In other words, distance is removed as barrier for the above application. The computer network thus creates a global environment for its users and computers. Other goal is to provide communication services (such as E-mail) and in general to provide robust transport network i.e., (highway) over which network applications can be built.

In Short:

• Share and access resources
• Provide communication services
• Provide robust transport network
