What is the E-mail? __71__ You can send messages in only a few seconds by email.
On the Internet there are many powerful computers called “servers” to help people send and receive emails. __72__ If you want to use the email service, you have to open at least an email account called a “mailbox”, just like we set up a mailbox in a post office. Some mailboxes are provided free of charge by ISPs, which you can get when you open an Internet account.
__73__ First you have to connect to the Internet and go to the homepage of the ISP providing free mailboxes. Then you’ll find an icon(符号)showing “apply for a free mailbox”. Click the icon, and an agreement about the rules for using the free mailbox will appear. __74__ Then you have to fill in a form about your basic personal information, and the name and pin of the mailbox. After finishing these, you will get a mailbox like this: your name @ mail server, for example: jack@163.com. The mailbox is separated into two parts by a separator “@”, which is read as “at”. The former part is the name of the mailbox. The latter is the domain name(域名)of the mail server. All mails to you will be received by the server and put into your mailbox. __75__.
