When two or more computers are connected to each other it is called a computer
network. There is a network of millions of computers spread all around the world
which is known as Internet. The word “Internet” comes from the Latin word “inter”
meaning “between” or “among,” and “net” stands for “network”. So Internet simply
means, “among or between networks.”
We can collect information, share information, communicate, sell and buy products
online, take online classes and do many more tasks using the Internet.
