What is a Network? 

First of all we must have to know about what is a network. So the network is the interconnection of two or more than two devices in such a way that they can communicate each other. In computer networks we can say that the interconnection of two or more than two end devices (computer, laptops, printers etc) for the sake of sending and receiving some amount of data is known as computer network.

What is Internet?  

The very simple and easily understandable definition of a internet is "The network of networks". Now what is meant by that? When different networks from the different areas or at the same areas wanna communicate with each other then internet formed. So we can say that "Internet is the interconnection of different networks in such a way that networks can communicate with each other".
