The Internet has one very simple job: to move computerized information (known as data) from one place to another. That's it! The machines that make up the Internet treat all the information they handle in exactly the same way. In this respect, the Internet works a bit like the postal service. . This sends a message from your computer to a server. It asks for a copy of the webpage. How is the information transferred? The information is too big to send in one go, so it is split up into.

A network is a group of connected computers that are able to send data to each other. A computer network is much like a social circle, which is a group of people who all know each other, regularly exchange information, and coordinate activities together. The Internet is a vast, sprawling collection of networks that connect to each other. IP (Internet Protocol) - for receiving and sending packets from network to network TCP (Transmission Control Protocol) - To ensure that those packets are arriving successfully in the same order, HTTP (HyperText Transfer Protocol) - for formatting data over websites and apps Table of Contents hide 1 GCSE Internet Technologies (14-16 years) 2 A-Level Internet technologies (16-18 years) 3 Internet 4 Basics of the internet 5 Structure of the Internet 5.1 1.

The DNS points the request in the right direction. Once the target server receives the request, it can send a response back to your computer. The data might travel a completely different path to get back to you. This flexible approach to data transfer is part of what makes the Internet such a powerful tool. What is the Internet? Internet Diagram #1 The Internet is a large collection of computers, all talking to one another over a network. All the computers run programs (e.g. servers and browsers) that let them talk to one another. Many of the computers on the Internet run a collection of programs called the World Wide Web, or simply the Web. Summary. The Internet is the backbone of the Web, the technical infrastructure that makes the Web possible. At its most basic, the Internet is a large network of computers which communicate all together. The history of the Internet is somewhat obscure. It began in the 1960s as a US-army-funded research project, then evolved into a public. The Internet Society, a nonprofit group established in 1992, oversees the formation of the policies and protocols that define how we use and interact with the internet. In this article, you will learn about the basic underlying structure of the internet. You will learn about domain name servers, network access points and backbones.

These are Internet routers that decide where to send your packets. Several routers are shown in Diagram 3, but only a few. Diagram 3 is meant to show a simple network structure. The Internet is much more complex. Internet Infrastructure The Internet backbone is made up of many large networks which interconnect with each other. As described above, the internet is a network of computers connected together and exchanging information with each other. The collection of websites that use the internet to send and receive data is called the World Wide Web (WWW). In other words, the World Wide Web uses the internet to transmit its data.

Switches. Network switches are central nodes that forward messages between nodes in the same network by rapidly creating and deleting connection points. You can think of them as the managers of the network, maintaining the flow of information between the devices in a network, whether wireless or wired. 3. Router.
