Electronic mail (e-mail) is the most common Internet service, since it is historically the first information service of computer networks and does not require high-speed and high-quality communication lines. Advantages over regular mail: - speed of message transfer; - an email can contain not only a text message, but also attached files (programs, graphics, sound, etc.). In addition, e-mail allows you to: send a message to several subscribers at once; forward letters to other addresses; enable answering machine E-mail - exchange of postal messages with any Internet subscriber.

E-mail address. The email address is written in a certain form and consists of two parts separated by the @ symbol: user_name@server_name The first part of the email address (user_name - user name) is arbitrary and is set by the user himself when registering a mailbox. The second part (server_name - server name) is the domain name of the mail server on which the user registered his mailbox. The email address is written only in Latin letters and must not contain spaces. For example, the mail server of the MTU - Intel company has the name mtu-net.ru. Accordingly, the names of user mailboxes will look like: [email protected]

Excerpts from the presentation:
History of email creation
1972 Ray Tomlinson, driven by the need to create simple means of communication for ARPANET developers, wrote basic programs for sending and reading electronic messages - he created an electronic mail system.
Advantages of email
- The letter will reach the most remote corner of the globe in a matter of minutes;
- There is no need to distract a person: you can receive and send mail at a convenient time;
- You can attach a file to an email.
How email works
To organize email, you need a server computer where your email mailbox will be located, which is a place on the server where messages are stored until the recipient requests them.
Mail clients
To work with mail, you need a client program.
There are many email programs, the most popular are:
- Outlook Express;
- The Bat!
- Webmail.
Outlook Express
When using the Outlook Express email client:
- Letters are downloaded from the server and stored on your home computer;
- Letters can be written without an Internet connection and sent at a convenient time;
- Anti-virus protection is not organized.
The Bat!
When using The Bat! email client:
- Program setup required;
- Messages can be viewed and deleted on the server. You can store letters on the server, or you can download them to your home computer and read and write answers without an Internet connection;
- Anti-virus protection is well implemented.
Web interface
Mail servers create their own interface for working with mail, which is accessible from the Internet Explorer window (here I would better use the word browser). When using Webmail:
- No settings are required to send and read letters;
- Letters are stored on the server;
- Letters can only be written and read online.
Email protocols
- Sending client messages is carried out using the SMTP protocol (Simple Mail Transfer Protocol - the simplest mail transfer protocol) - this is a simple protocol through which the message is sent to the provider's mail server, which immediately sends this letter through a system of Internet mail servers to the recipient.
- When receiving correspondence, the client computer interacts with the server using the POP3 protocol (Post Office Protocol 3). The incoming mail protocol is more complicated because... Mail cannot be allowed to fall into the wrong hands; the POP3 protocol involves checking the username and password.
An email address consists of two parts, separated by the @ symbol.
The @ symbol is called differently in different countries. The Americans and the British call this sign "at". For us it is a dog. The Germans see a hanging monkey in the outline of the @ symbol. For the British and French it is a snail. The Danes and Swedes call @ the trunk of an elephant, the Hungarians - a worm, the Norwegians - a pig's tail, the Chinese - a mouse, the Greeks - a little duck, the Finns - a cat.
Mailing address
- You can get a free mailbox on the mail servers of search engines Yandex, Rambler, Yahoo, Aport;
- Username - Login (login, login name, user mailbox name, account) is set by the user in accordance with the server rules;
- The username starts with a letter and can contain numbers and a hyphen. It is better not to use other symbols. Name size is limited;
- The email address is written only in Latin letters, cannot contain spaces, uppercase and lowercase letters do not differ;
- Access to the mailbox is carried out after checking the password;
- A strong password must contain at least 6 characters and cannot be the same as your login. It's better to use a digital password that you won't forget;
- When you create a mailbox, a security question is created. If you forget your password, you can access your mailbox by answering the security question. Only you should know this answer.
- Entering check digits when creating a mailbox is protection against robot programs.
Homework:
- Come up with login;
- Create a password.

Electronic mail (email, e-mail, from the English electronic mail) is a technology and the services it provides for sending and receiving electronic messages (called “letters” or “e-mails”) over a distributed (including global) computer network. That is, e-mail is a service for sending messages between subscribers on the Internet.
Slide 3
The emergence of email can be traced back to 1965, when Massachusetts Institute of Technology (MIT) employees Noel Morris and Tom Van Vleck wrote the MAIL program for the CTSS (Compatible Time-Sharing System) operating system. The MAIL command itself, built into the operating system, allowed CTSS users to send text messages to each other within the same computer. It had a format: that is, it was intended to solve specific user problems and assign tasks to programmers. How did email come about? MAIL (example: MAIL M1416 2962),
Slide 4
1971 Bolt, Baranek and Newman By 1969, BBN had developed the TENEX operating system. Ray Tomlinson was one of the TENEX systems programmers. The result of Tomlinson's work was the CPYNET program for copying files between two TENEX systems. The TENEX OS contained the SNDMSG program, which was almost a complete analogue of the same MAIL from CTSS. The syntax of Tomlinson's network version of SNDMSG was no different from the syntax of the MAIL command. With one exception. The program was universal and could send both traditional intra-machine messages and messages between machines. But how can a program distinguish between these two types of messages? Tomlinson decides to use the "@" symbol to separate the username and the address of the node on the network to which the message is sent.
Slide 5
The email address looks like this: [username]@[mail server name].[domain] @ (at) – delimiter character
Slide 6
Email is similar to regular mail. Only instead of paper and pen, you use a keyboard, typing the text of a letter in an email program or browser window. Mail servers act as post offices, and Internet channels serve as postmen. Mail servers store users' electronic mailboxes. As soon as the user looks into his mailbox, he will immediately see incoming letters. A mail server is a powerful computer, and as we know, all information on a computer is stored in the form of files. Therefore, an email box is nothing more than a certain area on a computer’s hard drive (disk space) allocated for storing incoming and outgoing letters from a specific user. Principle of operation
Slide 7
Mechanism for sending letters. Email transmission protocols. IMAP (Internet Message Access Protocol) is an application-level protocol for accessing email. POP3 (Post Office Protocol Version 3) is used by the email client to receive email messages from the server. Typically used in conjunction with the SMTP protocol. SMTP (Simple Mail Transfer Protocol) is a network protocol designed for transmitting email over TCP/IP networks. SMTP is used to send mail from users to servers and between servers for further forwarding to the recipient. To receive mail, the mail client must use the POP3 or IMAP protocols.

Slide 9
Typically, special email programs are used to create, send and receive email messages, such as Microsoft Outlook Express, Netscape Composer, The Bat! etc. Another popular way of working with mail does not involve using a special mail program - a regular browser is enough. The visitor just needs to go to his email page to send and receive letters. Popular mail services
Slide 10
Pros and cons E-mail has undeniable advantages: High speed of sending letters. The ability to simultaneously send the same letter to several recipients at once. You can attach a file of any format to the letter, for example, audio, video or photo. Anyone can master email. High reliability of email delivery. But there are some disadvantages: It is almost impossible to hide the address of your email box, so it is very difficult to protect yourself from such a thing as spam (mass mailing of advertising emails, often containing viruses or aimed at luring money or personal data from the user). Limit on the size of one message and on the total size of the email box. As computer technology develops, these restrictions become less noticeable, but most Internet portals that provide the ability to use e-mail still have them.
History of Email In an interview with Reuters, Ray Tomlinson, a senior engineer at BBN Technologies, could only recall that the entire email was written in capital letters, and was a quote from Lincoln's Gettysburg Address (November 19, 1863, by President Abraham Lincoln). gave a speech at Gettysburg at the opening of a new cemetery for victims of the Civil War). October 1971 is considered the birth date of email as a means of communication.
History of Email July 1972 - Larry Roberts wrote the first program that made it easier for users to use email. A study conducted by the Advanced Research Projects Agency (ARPA) showed that 75% of all network traffic ARPANET accounts for e-mail. The first mailing list appeared on the ARPANET network. Its founder was Steve Walker. John Vittal developed the MSG program, the first email program that was built on the all-inclusive principle and provided the ability to compose a response to a received message, forwarding letters and sorting correspondence.
History of Email 1976 March 26. Queen Elizabeth II of England sent a letter by email for the first time using the services of the Royal Signals and Radar Establishment (RSRE) in Malvern. Larry Landweber of the University of Wisconsin developed THEORYNET program, which provided sending email over a network of about 100 computer scientists. The system was designed to work in TELNET, April 12 is the smiley's birthday. It was on this day that Kevin MacKenzie, one of the apologists for “emotional” computers, wrote to the Message Services Group (MsgGroup) with a letter proposing the inclusion of some symbols denoting emotions in “dry” computer texts.
History of e-mail 1981 In order to satisfy the needs of American universities for high-quality network services and, first of all, e-mail, the CSNET (Computer Science NETwork) network was created, better known now as the Computer and Science Network. EUUG specialists (European UNIX Users Group) the EUNet (European UNIX Network) network was created specifically to provide users of UNIX systems with access to email and the ability to use USENET services, September 20. Based on the CSNET protocol, electronic postal communication has been established between Germany and China. It was on this day that the first email was sent from China to Germany.
History of email 1988 Users of the FidoNet network were able to exchange emails with correspondents connected to other networks. For the first time, a connection was established between commercial postal services and the Internet. Electronic mail was used for the first time to send advertisements. In the catalog Liszt electronic mailing lists (almost 72 thousand mailings were registered on a variety of topics). Casio PhoneMate presented the IT-380 E-Mail Link answering machine at the Consumer Electronics Show (CES). According to the company, this is the first device of this type that provides users with the opportunity View received email messages.
History of Email 1998 December. Software engineer Lin Hai and physicist Wang Youcai were convicted of distributing "virtual" leaflets via email to more than 250,000 other Chinese dissidents and foreign supporters of democratic reforms in the country. They were charged with inciting the overthrow of the city's government. Early in the morning of May 4, the “I Love You” virus began its journey through email networks. It turned out to be from the Philippines and was distributed through four hacked email addresses.
Organizing an email service on the Internet Electronic mail is a service for sending messages between registered addresses. The email address looks like where: mail.domain - domain name of the mail server, mailbox - identifier name (commercial at) - separator character.
Structure of an electronic message It consists of three parts: An envelope containing the addresses of the sender and recipients of the message, this information is used only when sending a message via the Simple Mail Transfer Protocol - a simple protocol for transferring mail to the recipient; it is not available; Header containing service information generated by programs involved in transmitting the message, such as the addresses of the sender and recipients, which may differ from those used in the envelope, the subject of the message, the time of sending, information about forwarding and the programs used to create the message, etc. .d., the title ends with an empty line; The body contains the message itself, created by the sender and to be delivered to the recipient.
Email protocols Simple Mail Transfer Protocol (SMTP) is used to send email messages over the Internet between transport agents and from MUAs to MTAs. POP (Post Office Protocol) is used to forward new user mail from the server to the user's workstation. Currently version 3 is in use; its command set is incompatible with previous versions.
MIME Standard for sending email on the Internet MIME (stands for "Multipurpose Internet Mail Extensions" - Multipurpose extensions of the Internet mail standard). The standard is described in the specification RFC 1521 "MIME - Multipurpose Internet Mail Extensions. Part one. Mechanisms for Specifying and Describing the Format of Internet Message Bodies". RFC 1521
Netiquette: Email Etiquette The main rule of Netiquette is the same as in any other etiquette: behave in such a way that you can be easily understood, do not create problems for others and do not interfere with normal dialogue, even if it is conducted via email. mail. Always behave in such a way as not to offend the person with whom you are corresponding online. Be sure to start your sentence with a capital letter and use periods. Names and titles must begin with capital letters. Text written in lowercase only, without periods or other punctuation marks, is difficult to read. The text, written only in capitals, is generally perceived when reading as a CONTINUOUS SCREAM.
Smiley Smileys (from smile smile) or emoticons (emoticon), on the Internet, are icons made up of punctuation marks, letters and numbers, denoting any emotions. The yellow smiling face was first drawn by American artist Harvey Ball.
