    We have already learnt that Internet is a vast computer network that links other smaller
                     computer networks worldwide.

                     It has various uses. In this chapter, we will learn about the popular use of the Internet,
                     i.e., E-mail.

                               WHAT IS E-MAIL?

                     E-mail stands for electronic mail. It is used to send messages to multiple people, sitting at
                     different geographical locations, within a few seconds. It is a fast and convenient way of
                     correspondence. We can also send or receive pictures, audios and videos with an E-mail.
                     They are called attachments.

                     ADVANTAGES OF AN E-MAIL

                     E-mails have various advantages, some of which are:

                       An e-mail can be sent anytime and from anywhere in the world.
                       An e-mail can be sent to many people at a time.
                       An e-mail can be easily forwarded to anyone without typing it again.

                       Sending an e-mail is fast in comparison to traditional mail.

                       Music, images or any other computer file can be shared with anyone by using e-mail.
                        If an e-mail does not reach its destination in the first attempt, the mail server automatically
                       sends it again.

                        If an e-mail is not delivered, you receive an e-mail explaining why the e-mail could not
                       be delivered.

                                                                                   Free email service providers
                               E-MAIL ADDRESS

                     To use e-mail services, we need to create an e-mail account. We can send and receive
                     messages from an e-mail account. Some of the most popular websites that provide the

                     facility to create free e-mail accounts.

                       www.gmail.com           www.rediffmail.com           www.yahoo.com           www.outlook.com
                     There is a specific format for e-mail addresses that includes a username and domain name
                     which is separated by @ (pronounced as ‘at’). The username is different for every e-mail

                     but the domain name remains the same for all the people using the same mail server.
                     For example:
                                                                                 Domain name
                                                              xyz@gmail.com

                                            Username

                                                                                             E-mail and Malware Safety  73
