1. Basics of the Internet

1.2. Basic concepts of instant messaging and instant messengers

The messaging system is one of the most accessible and popular means of communication on the Internet, in corporate and local networks. Messaging services are divided into offline messaging services (E-mail systems) and online instant messaging services (Internet Relay Chat and Instant Messaging Service).

Messaging systems have their own communication networks, most of which are built on a client-server architecture.

Offline messaging services

Offline messaging is carried out through the interaction of two programs - a mail server and a mail client.

To work with email, you can use both email clients and email web interfaces, which are located on email web servers. Using the web interface, you can work with mail directly on web mail servers.

WWW-based mail systems allow you to process mail messages on the Internet using a regular browser rather than an email program. They work on the “2 in 1” principle, combining the functions of a mail server and a mail client.

Online messaging services

IRC Service IRC (Internet Relay Chat) is the first online communication tool that provides big choice

channels (topics) for discussions with like-minded people. Chat is a text dialogue in real time.

Initially, the IRC service had one IRC network, which later split into several IRC networks. These IRC networks are not connected to each other and have their own names (DALnet, IRCnet, UNDERnet, RusNet, WeNet, IrcNet.ru, etc.). Each IRC network has its own topic areas or channels. You can download IRC clients on the Internet for Unix-like operating systems, OS/2, Windows systems and mobile phones.

You can use both IRC clients and Web chats to chat. Web chats are designed for exchanging messages on a server (web page) using a browser; in this case, you do not need to install a client application on your PC. Web chat is a web page where you can chat with other visitors in real time.

Instant Messaging Service

The result of the development of chat was the Instant Messaging Service (IMS). IMS is one of the technologies that provides communications on the Internet. In the instant messaging service, in addition to text messages, you can send sound signals, pictures, videos, files.

This service has its own networks. The IMS network architecture is based on the client-server principle. The IMS client program, which is designed for conducting conversations and instant messaging online through instant messaging services, is called instant messengers (IM).

As a rule, exchange networks have a separate server (some networks are decentralized) to which messengers connect, and their own interaction protocols. Most instant messaging networks use closed or proprietary protocols (proprietary protocols owned by only one network) to exchange information. Basically, each of these networks uses its own messenger.

There are usually no connections between different IMS networks, so a messenger on one network, for example ICQ, cannot communicate with a messenger on the Skype network. This means that in order to communicate with each other, users must register in the same service and install their messengers.

But there are also alternative messengers for instant messaging services that can work on multiple networks simultaneously. For example, the free open multi-protocol modular client (messenger) Miranda IM (or Trillian, Pidgin) allows you to connect to several networks simultaneously, which eliminates the need to install a separate messenger for each network.

In addition, as an alternative to proprietary protocols for IM, the open protocol Jabber (Jabber is a family of protocols and technologies) or XMPP was developed, used in many instant messengers (Jabber clients: Psi, Miranda IM, Tkabber, JAJC, Pandion and others). Jabber (chatter, chatter) is a system for instant messaging and presence between any two Internet subscribers based on the open XMPP protocol using the XML format. This is a new generation communication system.

There is no single central server on the network, Jabber is a decentralized (with decentralized servers), extensible and open system. Anyone can open their own instant messaging server, register users on it and interact with other Jabber servers. Jabber is used to organize communication on the Internet, local and corporate networks.

Modern instant messengers provide users with a lot of useful functions, such as IP telephony, video chat, indication of user network status, etc. To communicate in the instant messaging service, you can use both a desktop IM client (messenger) and a web version of the client (for example, Google Talk Gadget, JWChat, Meebo, MDC, etc.).

List of main functions that modern instant messengers can provide:

chat (video chat, text and voice);
VoIP services: calls to a computer, calls to landlines and Cell phones;
ability to send SMS;
file transfer;
tools for real-time collaboration;
the ability to chat directly on the web page;
reminders and alerts;
storing communication history for each contact;
indication of the network status of users (online, away, etc.) included in the contact list.

The most popular messengers

ICQ(I Seek You - I'm Looking for You) is a popular program (the most common Internet pager) for communication in real time. Since ICQ is an outdated centralized network with a closed protocol, experts currently recommend that users switch from the ICQ system to Jabber.
Skype- the most widespread messenger in the world with a closed protocol. Provides the ability to call landlines and mobile phones and receive calls. The latest versions of this messenger have implemented the “Video Call” function, with which users can talk and exchange full-screen video from Web cameras installed on users.
Miranda I.M.- multi-protocol instant messaging messenger with open source for working on the Internet or local network. Supports instant messaging protocols: ICQ, IRC, Jabber, Google Talk, Skype and others.
Google Talk client is a desktop IM client (messenger) Google Talk, and Google Talk Gadget is a web client that works in any browser with the Abobe Flash plugin. Google Talk is Google's instant messaging service that allows you to communicate using voice chat and text messages. Google Talk uses the XMPP (Jabber-compatible) protocol and allows you to communicate with other participants in the Jabber network.
Mail.Ru Agent client is an IM client (messenger) that provides text, voice communication and video chat. Supports ICQ, i.e. is an ICQ client.
VoxOx(voxox.com, version 2.0) - a modern and promising open-source multi-protocol messenger that supports ICQ, Jabber, MSN, Yahoo! Messenger and others. VoxOx contains many useful features and competes with the world's most widely used instant messenger, Skype.
MyChat- client-server chat for local, corporate and city networks.

Interactive communication on the Internet

In addition to the fact that we can communicate with friends, relatives, business partners or simply acquaintances personally (“face to face”), write them letters, call them on the phone, etc., we can also resort to actively developing Currently, interactive communication via the global Internet in real time. And so, the purpose of our lesson will be to determine the forms and means of communication through a global computer network and to obtain practical communication skills on the Internet.

Forms of communication:

Recently, interactive communication on the Internet in real time has become increasingly widespread. Increasing data transfer speeds and increased computer performance allow users not only to exchange text messages in real time, but also to carry out audio and video communications. There are quite a large number of servers on the Internet on which interactive communication is implemented. Any user can connect to such a server and start communicating with one of the visitors of this server or participate in a group meeting. If your computer, as well as the computers of your interlocutors, are equipped with a sound card, microphone and headphones or speakers, then you can exchange audio messages. In order for you to see each other, that is, exchange video images, video cameras must be connected to your computers. In this case, of course, the quality of sound and image largely depends on the speed of the modem and the bandwidth of the communication channel. So, interactive communication on the Internet can be implemented in the form of conversation, audio and video conferences (Web chats, communication via Skype, ICQ, IRC, teleconferences, forums).

Recently, interactive communication on the Internet in real time has become increasingly widespread. Increased data transfer speeds and increased computer performance give users the opportunity not only to exchange text messages in real time, but also to carry out audio and video communications.

Interactive communication servers. There are thousands of Internet Relay Chat (IRC) servers on the Internet that provide interactive communication. Any user can connect to such a server and start communicating with one of the visitors of this server or participate in a group meeting.

The simplest way communication conversation (chat) is an exchange of messages typed from the keyboard. You enter a message using the keyboard, and it appears in a window that all meeting participants can see at the same time.

If your computer, as well as the computers of your interlocutors, are equipped with a sound card, microphone and headphones or speakers, then you can exchange audio messages. However, a “live” conversation is only possible between two interlocutors at the same time.

In order for you to see each other, that is, exchange video images, video cameras must be connected to your computers. Regular analog video cameras are connected to special video cards, and digital cameras are connected to the parallel port of the computer.

Of course, the quality of sound and image largely depends on the speed of the modem and the bandwidth of the communication channel, which must be at least 28.8 Kbps.

Interactive communication on Internet servers can be implemented in the form of text messaging, audio or video conferencing.

To organize interactive communication, you need special software (for example, the NetMeeting program, which is part of Internet Explorer).

Programs that enable interactive communication on the Internet:

Skype is a popular application designed for voice communication over the Internet. It was thanks to this program that IP telephony became accessible to ordinary users. Today Skype has many competitors, but its developers are constantly improving the program, adding new features, improving its security and optimizing the user interface. In this course, we will focus on the key functions of the latest – fourth – version of the program.

Necessary equipment

To work with the Skype client, a “mid-statistical” computer with speakers is enough - the user will be able to communicate in a text chat and hear the speech of the caller; To speak yourself, you need a microphone. There are no special requirements for it to work in Skype - the main thing is that the microphone is installed correctly. The most comfortable communication is provided by headsets recommended for Skype (more details about them can be found on the website www.). In addition, special telephone sets are available for sale to work with this client. When using them, a PC is no longer needed: connect your phone to the Internet, log in and have a great conversation! After a while, you will no longer feel the difference between Skype and a regular landline phone. And if we talk about costs, Skype calls are often cheaper than calls via regular phone. You may also need a webcam for Skype. With its help, interlocutors will be able not only to hear, but also to see each other.

Communication using Skype

Skype services provide users with several interaction options. You can conduct telephone conversations, make video calls, or exchange text messages in the same way as when talking, for example, on ICQ (but, unlike ICQ, offline messages sent via Skype will be delivered only when both participants in the dialogue are in Networks). Additional features include functions for sending SMS and files, as well as voice mail.

ICQ - (I seek You - I'm looking for you) is a centralized instant messaging service on the Internet, currently owned by the investment fund ***** Group (Russia). Contents

Characteristic

ICQ is a centralized instant messaging service using the OSCAR protocol. The service user works with a client program (the so-called messenger) running on a device connected to the Internet. The messenger connects to the server. Through the server, searching and communication with other clients is carried out, and the exchange of service data and messages between users can be carried out both through the server and without its participation. As with most powerful network systems that serve a huge number of client requests, this server is not the only one and some of them are clusters of servers.

The service is commercial, but its use is free. Operates the ICQ Inc. service. Since its inception, the service belonged to its developer, Mirabilis, and was sold in 1998 American company AOL, and in April 2010 - to the Russian investment fund Digital Sky Technologies (DST). In addition to ensuring the functioning of the service, ICQ Inc. develops client programs and maintains an auxiliary web portal.

Over the years, ICQ has released many clients and undergone many changes. It is estimated that about 15 million people actively use the service, and registered accounts- about 400 million. Some companies indicate UIN numbers in their contact lists on official websites. ICQ is often used by technical support services for instant assistance.

With IRC (Internet Conversation Communication), you can have real-time conversations on the Internet. This system provides a wider range of options than simple chat. To connect to the necessary channels (discussion groups or rooms), you need a separate program - the IRC client. With IRC, you can communicate on multiple channels at the same time, as well as have private conversations between two people. IRC uses the same rules for safe use as chat rooms. For getting additional information about IRC visit the website *****.

Instructions for safe chatting

Children who chat need to know how to do so safely. Everyone should remember the following chat house rules.

Don't trust anyone with your personal information.

Report any offensive behavior from participants to the chat administrator.

If you feel uncomfortable being in a chat, leave it.

If you don't like something, be sure to tell your parents about it.

Be considerate of other people in chat.

Real-time communication Via local network Winsent Network Assistant Via the Internet Well-known social networks for communication: VKONTAKTE FACEFOOK MAIL. RU Twitter Odnoklassniki Skype My. Space ICQ

There are thousands of servers on the Internet where real-time communication is realized. The simplest way to communicate is by exchanging messages typed from a keyboard. If the subscriber's computer, as well as the interlocutor's computer, is equipped with a sound card and a microphone and headphones or speakers, then they can exchange audio messages. What does a user need on the Internet? Information. Text, graphic. You can get it both by browsing websites and by communicating online. There are three main ways to communicate on the Internet. This is mail, forum and chat in in social networks. When using mail and a forum, any amount of time can pass between the question and the answer of the interlocutors; in the process of sending a letter or post, users do not even know whether the addressee is on the Internet, whether he will read what was written and whether there will be a response from him. This is not real-time communication, this is delayed communication and we are not interested in that.

"E-mail allows subscribers to exchange messages that take some time between sending and receiving. Instant messaging systems allow subscribers to exchange information in real time, that is, with virtually no delay. Increased data transfer speeds and increased computer performance allow users to not only exchange text messages messages in real time, but also to carry out audio and video communications. Instant messaging systems exist for both the global computer network Internet and local networks.

Internet telephony allows an Internet user to use computer-to-computer, computer-to-phone, and phone-to-computer telephone communications. Internet telephony providers provide such communication using special Internet telephone servers that are connected to both the Internet and the telephone network. IN last years IP phones, which connect directly to the Internet and do not require a computer to use Internet telephony, are becoming increasingly common.

SMS and MMS messages. Mobile phone users can Fig. 2. 11. IP phone exchange SMS and MMS messages. SMS messages can also be sent from a computer connected to the Internet to a mobile phone.

Network Assistant (Nassi for short) is a program for communicating and effective interaction on a local network, which does not require a dedicated server. Key features: multi-channel chat, shared drawing board, instant messaging, file transfer, process management on a remote computer, screen copy/clipboard viewing remote computer, usage statistics, remote event indicators, etc. Network Assistant supports communication between interlocutors of up to 10 users.

Real time communication concept

The increased speed of data transfer in networks and increased computer performance today enable users not only to communicate in real time using text messages, but also to carry out audio and video communications.

Sitting at home in your favorite chair, you can send letters that will reach faster than a telegram and instantly receive an answer, find out last news and chat with friends and business partners.

You can correspond via email. But you need to wait until the recipient goes into his mailbox, reads the letter and responds.

This could take more than one day. And if there are a lot of questions, such correspondence can last for months.

Correspondence or communication in real time allows you to receive answers instantly.

Advantage live communication is that if you have a computer, special software and an Internet connection, you can talk to anyone from anywhere in the world.

Real-time communication servers (Chats)

There are many servers on the World Wide Web that implement the communication process in real time. Anyone can connect to such a server and start communicating with visitors to this server or participate in a group meeting.

The simplest text way of communication in real time - chat(English) chat)- exchange of messages typed from the keyboard.

The user enters text from the keyboard, and it appears in a window that is simultaneously visible to all meeting participants.

If the user's computer and other interlocutors are equipped with a sound adapter, microphone and speakers, then they can exchange audio messages. However, a “live” conversation is possible only between two interlocutors at the same time.

In order for you to be able to see each other, i.e. exchange video images, you must be connected to your computers Web cameras.

Internet telephony

One of the most popular representatives of programs that provide the ability to transmit voice and image is Skype.

Skype is a program not only for text correspondence and voice conversations, but is also designed to create various conferences and video calls using the same Web camera.

The program has a bunch of different features and settings.

You can also call landlines and mobile phones around the world for pennies.

And not only make calls, but also receive calls.

Interactive communication via ICQ, QIP

Recently, interactive communication via servers has become increasingly popular. ICQ(this abbreviation is formed from the consonance of the words “ I seek you"- I'm looking for you) and QIP.

Interactive communication systems integrate various forms of communication:

email
text messaging
Internet telephony
file transfer
searching for people online, etc.

Currently, there are more than 200 million registered users in the ICQ system.

Each user has his own unique identification number.

After connecting to the Internet, the user can start communicating with any user registered in the ICQ system and currently connected to the Internet.
