Internet
Representation of a network of roads at a fraction of the Internet.
Internet (Ahabkp) and (Almuammam) system of computer networks linking the computers around the world united by the Protocol is a protocol Internet. Internet connects millions of networks between public and private academic institutions, government and business enterprises and vary in scope between local and world and connect with different technologies, from copper wire and fiber optic and wireless links, these networks also vary in internal structure and technically administratively, as managed in isolation from the other decentralized and do not depend on any of them run on the others.
Download today's Internet a great deal of data and services, perhaps the most common on high-text pages published on the Web, as it carries the services and other applications such as mail and instant conferencing, and file transfer protocols. And voice dialing and others.
, And such mutations in the media history of the Internet today has become a social and cultural impacts in all parts of the world, and may have changed the traditional concepts of several areas such as employment, education and commerce and the emergence of another form for the information society.
Name
The name of the Internet consists of a prefix (Inter inter), which in English means "between" and the word (Net net), which in English means "network", or "network interfaces" and the name sign on the structure of the Internet as "a network of networks" or "network of networks, "and with this error have been sweeping the Arab media called" the international network of information, "believing that the inter section in the name is an abbreviation the English word" international ", which means" international ", and it suggests the fact that the network is a UN project.
Internet name of science, and sometimes known as a shortcut to "Network".
Technology of computer networks and the Internet
Is not what it seemed at first glance, the Internet depends what is known in the science of network design as "simple design", because the Internet is doing a single initial, simple, and it is the delivery of digital message between two nodes, each title unique path of "storage and scroll" between with a lot between the sending node and receiving node, and so can not predict in advance which path will take him the message through the network as the message can be divided into parts each take a different path and arrive in the order is not their original order on which the receiving node to re-order message , and is a class of network protocols known as the conduct of packets
Do not put Ahabkp (Internet) any prior assumptions about the nature and content of the message or purpose of being sent or how to use and do not try to make any handlers on the message or content is what it takes to be sent between two points. Every "intelligent" virtual network is shown in fact in the application layer above the transport layer, and all the value added to the network lies on the edge and not in her heart, which consists of marches (routers) that do not distinguish between messages, whether it involves mail message, or visual stream (video) or data for any application or service of built-up Ahabkp (internet).
Over this infrastructure for the delivery of data based many applications such as mail and file transfer and the flow of video and audio, and chat and chat, and many others, and through which can transfer any digital data.
Internet itself does not contain information but rather is a way to transfer information stored in files or documents in one computer to another. It is therefore common mistakes to say that information found in Ahabkp (Internet) and the right to say that information found through the use of Ahabkp.
Ahabkp designed from the outset (the Internet) so that they are immune to the crash. The most important element is free from the master node or central place on the lines have to pass it. Thus, there are a number of alternative fonts when you send your information via Ahabkp and indicate the way only when the transfer of information, depending on the vacancy line of pressure, and the disruption line is used for another line. But the decentralization of the technical side is not followed in the administrative side of the Habkp, so-called Internet governance, ICANN ICANN is an international supervisory body on the version of Internet addresses and tracking indirectly to the United States of America, and is run by the main nodes in the DNS more international countries.

History of the Internet
The Internet was a result of the GTZ project which was launched in 1969, a project of the Ministry of Defense of the United States. This project is established for the name of several U.S. military across computer networks linking universities and research institutions, for the optimal exploitation of computational capabilities of computers available.
In the first of January 1983 and replaced the United States Department of Defense Protocol) NCP in force in the network and replaced it with package Bmeevaq Muaiq (protocols) Internet. Of the things that contributed to the growth of the network is to link the "National Science Foundation" Universities in the United States to each other, which facilitated communication between university students and exchange of electronic messages and information, to enter the universities to the network, the network took in the expansion and progress and taken it college students are contributing their knowledge and saw the light browser "Mosaic", and the researcher "Gopher" and "Archie" It's a giant "Netscape" is originally from the efforts of the students before they adopted the mind to take it to the commercial and the outcome of the later.
Did not have engineers who planned the network in its infancy, the lowest perception of the status of the network today, and attributed the success of decentralization on the giant network or in other words, no one party controlled the course of events on the network. Meevaca governing the network (protocol) to communicate and decide which work of this Almivaq are the "engineers the Internet" is independently examine and determine the types of Moaafik applicable to various network services (HTTP, FTP, IRC), etc. ..
Engineers Ahabkp (Internet) are a factor in the success of the network where the public and open for all to pitch. Without the Internet, I would sit in your home and you read this article and for its many large companies today are dependent on supply of services in the Internet.
Ahabkp not being used widely until the early nineties of the twentieth century, although Tovralttabiqat and guidelines that make it possible to use the Internet and has been around for nearly a decade. On 6 August, August 1991, in the laboratory of the European particle physics and CERN, which is located on the border between France and Switzerland, the World Wide Web publication of the draft Web site, which was invented by English scientist Tim Berners-Lee in 1989.
There developed a Web browser to violawww, based on the hypercard. And the right web browser "Mosaic" MOSAIC. In 1993, at the National Center for supercomputing applications at the University of Illinois have been issued a copy of the 1,0 MOSAIC "Mosaic", and by late 1994 there was a marked increase in public interest in what was formerly for academic interest only. And by 1996 became Ahabkp use of the word has become common, and therefore, it was a cause for confusion in the use of the word Internet as a reference to the World Wide Web site.
In the meantime, over the past decade, the use of Ahabkp (Internet) steadily. During the nineties, it was estimated that Ahabkp has increased by 100% annually, with a brief period of explosive growth in 1996 and 1997. This growth is often due to the lack of central administration, which allows organic growth of the network, and also because of the property open to Muaiq (protocols) the Internet, which encourages individuals and companies to develop and sell the plant and also prevents one company from exercising too much control over the network .
Uses the connectivity of the network (Internet)
Progress Ahabkp many uses communication to users, include the fields of information, business, academic, political and medical ... Etc., but can say that all services provided by Ahabkp (Internet) is a communications services. It serves individuals, institutions and organizations, official and civilian alike. Communication and uses of the Internet continues to grow, and uses the same old evolve and increase the effectiveness and ease and potential.
Some examples of uses of the connectivity Habkp (Internet)

Common uses of the network (Internet)
E-mail E - mail
E-mail is a term used to send text messages between the groups in the electronic equivalent method to send messages and blogs before the advent of the Internet. Even in the present time, it is important to differentiate between e-mail and the Internet e-mail procedure. After all, the Internet mail may be transmitted and stored in the form of non-encrypted networks and other devices outside the control of both the sender and the future. During this period (transition period) of the possible contents of the mail to be read and tampered with through a third party, if the mail was of some importance. E-mail systems of procedure did not leave the data networks of the company or institution, which is more secure.
Web
A lot of people use the terms Internet and World Wide Web (or web only) that they are similar or the same thing. But in fact the terms were not synonymous. Ahabkp (Internet) is a collection of computer networks connected together by copper wire and fiber optic cables and wireless connections and so on. On the contrary, the Web is a collection of documents and related sources together, connected with each other via links and high Internet addresses. Otherwise, the global network and one of the services that can be accessed through the Internet, like e-mail and share files and others.
Programs that can access to web resources called the User Agent. In the normal case, web browsers such as Internet Explorer or Firefox you access to web pages and enables the user to roam from one page to another via hyperlinks. Web Page can contain almost a combination of computer data, including photos, graphics, audio, text, video, multimedia and interactive content including games and others.
Remote Access
Internet allows computer users to communicate with other computers and servers information easily, regardless of the position of the world. This process is known to enter tele. Can be done without the use of techniques to protect or encrypt or Authentication. This encourages new types of domestic work, and share information in many industries 0

Cooperative Systems
I have led a low cost calling Ahabkp (Internet) and the exchange of ideas and knowledge, and skills to the development of collaborative work systems and the emergence of a large cooperative. Is not possible to only connect cheap and widely across Ahabkp (Internet), but allows for groups with similar interests to create a cross-site easily. An example is the free software movement in software development, which produced a system for Linux and GNU GNU from scratch and took the development of Mozilla and OpenOffice.org (formerly known as Netscape axes and Star Office). Films such as Zeitgeist spirit of the age have had extensive coverage on the Internet, while being almost ignored in the mainstream media.
Chat Ahabkp (Internet) and whether in the form or IRC channels, or through instant messaging allow colleagues to stay in touch through the very convenient way of working at their computers all the time. The exchange of files, whether they contain the sound image or any other type of files and supports the joint work between team members.
Control systems allow copy version of the joint task forces and Amlpaly sets of documents of cooperation in their work. Thus, to avoid being clear what was written by another colleague, unintentionally and that each team members collaborating to create each of the documents and add their ideas and add the changes.
There is currently no other systems in this area, such as Google Calendar google calendar, or BSCW system or Sher Point.
Voice
Voice over Ahabkp (Internet) depends on the transfer of sound through Meevaq (protocol) Internet. This phenomenon began as a choice and utility systems, IRC chat for the transfer of sound in one direction. Spread in recent years many VoIP systems have also become easy to use and comfortable like a regular phone. These systems is the use of promising the Internet with far less expensive than ordinary phone call, especially for long distances.
The sound quality is still often vary from one word to the other and will need some time to become the same quality of traditional such as telephones. Become increasingly popular in the world of gaming, as a form of communication between the players. Of the most popular in audio over the Internet is a system Skype
Feeder Service
Feeder service is a service able to follow what comes in the locations provided by the go without the need to spin it to her in order to verify if he had a new post them, and it is not the way that prevailed previously not actually require in terms of location because the user is requesting this type of content penguin readers Feeds, whenever they want running the same phase you are working with Web browsers, and does not require disclosure of any amount of personal data by the user of the site, not even an email address, and this Valmtgm only where the user is, and can not use it does not please him or imposed on it. Include in its simplest form-feed a title and a summary of the topic, and a link to the full text of news on the publisher's site issue. There are several formulas for the deployment Feeds, including the Atom (disambiguation) and RSS and RDF.
Marketing
Become Ahabkp (Internet) a large market for companies, some large companies inflated their work by taking advantages of low cost of advertising and trade across the Ahabkp (Internet), and who knows e-commerce. It is considered the fastest way to disseminate information to a large number of individuals. As a result, the work of the Internet revolution in the world of shopping. For example, someone who can be required to buy a CD via the Internet and will be touched by regular mail within two days, or can be downloaded directly via the Internet if possible. The Internet is also facilitating the process of personal shopping, which allows a company to market a product to a particular person or group of people better than any ad center.
Examples of personal shopping, communities Ahabkp (Internet) and entered by thousands of users Ahabkp to declare themselves and make friends through Ahabkp. Since the users of these communities between the ages of 13 and 25 years, when they declare themselves so they declare about their hobbies and interests, and here you are marketing companies Ahabkp (Internet) use this information to advertise products that are approved desires and interests you can shop from any anywhere in the world via the Internet.
