Easy to Understand Definition of a Computer Network
By definition a network is a group or system that interconnects components together. A network of retail stores, for example, implies some sort of relationship between the stores. A railroad network suggests that the tracks interconnect at different points. And a computer network interconnects computers.
By far the most famous computer network in the world is the Internet. The Internet is, in fact, a collection of smaller networks that are interconnected together – a network of networks if you can imagine that.
