E-mail

We have learned to use IE to browse the WWW, the following we come to learn the Internet's another very widely used services - e-mail.

A. Basics of e-mail

1. E-mail

E-mail, also known as E-mail (Electronic mail), is the use of computers to send and receive electronic media through the network of letters.

E-mail is one of the earliest information transfer services on the Internet, and has become an important communication tool in contemporary times. According to the statistics released by China's CNNIC, as of December 31, 2006, 56.1% of China's Internet users were using e-mail service.

2. The emergence of e-mail

E-mail was born in the fall of 1971, invented by Ray Tomlinson, who was then an engineer at Bolt Bellanick Newman Research (BBN) in Cambridge, Massachusetts, a company employed by the U.S. military in the construction and maintenance of the ARPAnet network (a predecessor of the Internet). predecessor) construction and maintenance. Tomlinson researched existing programs for transferring files, as well as information programs, and developed a new set of programs that could send and receive information over a computer network. In order to provide people with easily recognizable e-mail addresses, Tomlinson decided to use the "@" symbol, which was preceded by the user's name and followed by the address of the user's e-mail address. Email was born.

There were too few people using the ARPAnet network at the time, and the speed of the network at that time was about 3 Kbps, which is one-twentieth of the speed of the 56 Kbps Modem we use today. So the first e-mail users could only send short messages, and could not transfer multimedia information such as pictures and sounds as they do now.

In the 1980s, the rise of the personal computer led to the spread of e-mail among computer buffs and college students. By the mid-1990s, the birth of the Internet browser and the surge in the number of Internet users led to the widespread use of e-mail.

3. Email Mailboxes and Mail Servers

Email services, like WWW services, use a client/browser mode of operation. Mail server is the core of the Internet mail system, it is similar to the role of the post office in the artificial postal system, with the help of the mail it provides sending, receiving, forwarding and other services to achieve the user's mail storage and forwarding.

On the Internet, if a user wants to use a mail server to send and receive e-mail, the user must have a legitimate account on the server, including the user name and password, so that the user has its own mailbox in the mail server; e-mail is essentially a hard disk space allocated to you by the ISP on the mail server, and the mailbox of the artificial mail delivery system. similar to a mailbox in a manual mail system.

The unified format of e-mail address is as follows:

Username@Hostname

It consists of two parts: the second part is the domain name of the mail server (IP address can also be used), and the first part is the user's username in the mail server, with "@" (pronounced as "＠") in the middle. The first part is the user name of the mail server, separated by "@" (pronounced "at"). For example: webmail@163.com, cheng@cqys.cn, cheng@cqys.net and so on.

Electronic mailboxes can be obtained in two ways, one is to apply for a paid mailbox from an ISP and the other is to apply for a free mailbox on the Internet.

4. Software for sending and receiving e-mail

When receiving emails from mailboxes of mail servers, you can use POP3 (Post office protocol 3) or IMAP (Interactive mail access protocol) protocols, etc. Generally, servers that support POP3 protocol are more, POP3 provides the function of storing information and is responsible for saving incoming emails for users.
