How does the Internet work?

There in the inquiries department you will find one of the employees to guide you The location of the store, or you can use a map of the place to show the shortest way To get to it, it tells you, for example, to go up the north stairs and then walk down the right aisle until you get there.

This aforementioned metaphor is roughly how the network works; the Internet is the commercial center, and it is full of various sites. When you want to access a certain piece of information, you open your browser and type the name of the site. The browser connects to your computer via the Internet settings, and from there it connects to a specific server called the DNS Server, which asks it for the server address, just as a call center employee does, giving it the email address in the form of its Internet number. Then the browser goes to the address to start the request, and the requested pages are displayed on the screen. Computer.

between The computer obtains the website's private internet address. And between browsing, there are routers that guide the computer to the shortest paths (hops) to obtain the required information, and thus it works like a map that shows the location of the store.

The origin of the Internet

The Internet was established in 1969 to serve the US military by connecting a large number of computers in universities and research centers together to achieve the best exploitation of their computational capabilities. It began with a network called ARPANET, then the NCP protocol was replaced by the US Department of Defense in 1983 with another protocol suite, TCP/IP, which is better, and these are the same protocols in use until now.

Internet infrastructure

It is a huge number of servers, switches, routers, and fiber optic links, extending across the entire globe, to reach all devices at the same time. The process of building and developing the infrastructure took more than four decades to reach what it is today.

Internet Protocol

It is a special language and rules used for transfer and exchange. Information and data over the network Internet. Initially, the NCP protocol was the one used, but with the development of the network and the development of Areas Its use has necessitated the need for new protocols to meet the new and increasing requirements of users, especially after the emergence and development of multimedia communication, e-mail services, etc.

Currently, the Internet Protocol is TCP/IP, which is a set of protocols used to transfer data over the Internet, and each type is specialized in transferring a specific type of data. For example, the protocols designated for broadcasting multimedia files Media Streaming differ from the HTTP website browsing protocol and those used for exchanging mail SMTP, and so on.
