The World Wide Web is not synonymous with the Internet, which pre-dated the Web in some form by over two decades and upon which technologies the Web is built. The Web began to enter everyday use in , when websites for general use started to become available. In addition to text , web pages may contain references to images , video , audio , and software components which are either displayed or internally executed in the user's web browser to render pages or streams of multimedia content. Multiple web resources with a common theme and usually a common domain name , make up a website. Websites are stored in computers that are running a web server , which is a program that responds to requests made over the Internet from web browsers running on a user's computer.

Internet and its application

Yet there are a few elements that have stayed constant and that provide a coherent thread for examining the origins of the now-pervasive medium. The first is the persistence of the Internet—its Cold War beginnings necessarily influencing its design as a decentralized, indestructible communication network. The second element is the development of rules of communication for computers that enable the machines to turn raw data into useful information. These rules, or protocols An agreed-upon set of rules for two or more entities to communicate over a network. Facebook is a simple example of a protocol: Users can easily communicate with one another, but only through acceptance of protocols that include wall posts, comments, and messages.

This whitepaper explains the underlying infrastructure and technologies that make the Internet work. It does not go into great depth, but covers enough of each area to give a basic understanding of the concepts involved. For any unanswered questions, a list of resources is provided at the end of the paper. Any comments, suggestions, questions, etc. Where to Begin? Internet Addresses Because the Internet is a global network of computers each computer connected to the Internet must have a unique address.

Internet of Things is a recent technology that creates a global network of machines and devices that are capable of communicating and exchanging data with each other through the Internet. There is a difference between the Internet of Things and the Internet. Internet of Things can create information about the connected objects, analyze it, and make decisions; in other words, one can tell that the Internet of Things is smarter than the Internet. Security cameras, sensors, vehicles, buildings, and software are examples of things that can exchange data among each other. As the number of real-time applications devices that need smart connections among each other is increased, the Internet of Things challenges will also increase.

Internet: Applications

The history of the Internet has its origin in the efforts to build and interconnect computer networks that arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France. Computer science was an emerging discipline in the late s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. Independently, Paul Baran proposed a distributed network based on data in message blocks in the early s and Donald Davies conceived of packet switching in at the National Physical Laboratory NPL and proposed building a national commercial data network in the UK. The network was built by Bolt, Beranek, and Newman.

Richard C. Van Sluyters, O. A college student plugs into the Internet jack in his residence hall room to communicate daily with friends and family via electronic mail e-mail 1. A health professions student subscribes to an electronic mail list and gains instant access to a lively dialog among her future colleagues on hot topics in their field. A man, worried about a tick bite a friend got on a Sunday hike, connects to the Centers for Disease Control in Atlanta to read the latest information about Lyme disease and to download color images of its characteristic skin rash.

The Internet is an increasingly important part of everyday life for people around the world. But if you've never used the Internet before, all of this new information might feel a bit confusing at first. Throughout this tutorial, we'll try to answer some basic questions you may have about the Internet and how it's used. When you're done, you'll have a good understanding of how the Internet works , how to connect to the Internet , and how to browse the Web. The Internet is a global network of billions of computers and other electronic devices.

The History of the Internet

Но Цифровая крепость никогда не устареет: благодаря функции меняющегося открытого текста она выдержит людскую атаку и не выдаст ключа. Новый стандарт шифрования. Отныне и навсегда. Шифры, которые невозможно взломать. Банкиры, брокеры, террористы, шпионы - один мир, один алгоритм. Анархия.

Невзламываемый шифр - математическая бессмыслица. Он это отлично знает. Стратмор провел рукой по вспотевшему лбу. - Этот шифр есть продукт нового типа шифровального алгоритма, с таким нам еще не приходилось сталкиваться. Эти слова повергли Сьюзан в еще большее смятение.

 Потому что Стратмор обошел систему Сквозь строй? - Фонтейн опустил глаза на компьютерную распечатку. - Да, - сказала .

Это за четыреста-то баксов. Я сказал ей, что даю пятьдесят, но она хотела. Ей надо было выкупить билет на самолет - если найдется свободное место перед вылетом.

Компьютеры терпеть не могут бесконечности, поэтому выдают девятки.  - Она показала ему другую колонку.  - Видишь. - Вижу, - сказал Бринкерхофф, стараясь сосредоточиться на документе. - Это данные о сегодняшней производительности.

Директор метнул на нее настороженный взгляд, но Мидж уже бежала к аппарату. Она решила включить громкую связь. - Слушаю, Джабба. Металлический голос Джаббы заполнил комнату: - Мидж, я в главном банке данных. У нас тут творятся довольно странные вещи.
