                 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.

                 E-mail is an online communication system. With e-mail, you can send and receive
                 electronic messages. Your messages are delivered instantly to people anywhere
                 in the world, unlike traditional mail, which takes a lot of time.

                    It is sent and delivered immediately if you are connected to the Internet.

                    It is a free tool. You can send and receive messages free of cost.
