Internet

The Internet (English: Internet) is defined as a global network that includes millions of computers from more than 190 countries, and they are connected to each other for the purpose of exchanging data, news and opinions. The Internet is the largest computer network in the world, due to the huge number of computers and servers connected to each other from around the world by routers (Switches), it is similar to the mechanism of work with home networks or those in companies, but they differ in a number Connected devices.

The most important Internet protocols

Several protocols are used in the Internet to facilitate communication between network devices. Among these protocols are the following: [3] [4]
  • Internet Protocol (English: IP): The Internet protocol is the basis for other protocols, and is responsible for making basic communications between connected devices, so that each connected device has its own address represented by numbers.
  • Hypertext Transfer Protocol (English: HTTP): It is a set of rules agreed upon for the purpose of transferring files, such as images, sound, documents, and others across the World Wide Web, as any visit to any webpage will be used. This protocol is in it.
Web servers contain what is called (English: Daemon), which is a program that receives requests for hypertext transfer protocol sent through a client to this protocol (English: HTTP Client), which is an example of a web browser, when the user visits a site using a browser Then, a request is sent to the hypertext transfer protocol for the IP address (English: IP address) indicated by the website address , after which it is answered by the program that transmits and sends files related to the web page to it.
  • HTTPS: This is a more secure version of the regular hypertext transfer protocol, as connections made with it have a protection layer that is not present at the end.
  • File Transfer Protocol (English: FTP): The file transfer protocol is the oldest of all Internet protocols except the Internet Protocol, as it became available for use in 1971 AD. The file transfer protocol is used to upload and upload files from one device to another device within the network, and this protocol is not secure if its settings are not set correctly, and the connection may be compromised if the settings are left the same.
  • Secure Transfer Protocol (English: SSH): It is a method for transferring data securely. It contains many features of the file transfer protocol, but it is more secure, contains more features, and allows access to servers and the implementation of remote commands.
  • TELNET Protocol: TELNET provides access to and control of computers remotely. However, it lacks secure communication standards, as it does not encrypt the data sent and received over the network.


website

The website (in English: Website) is a place on the Internet that includes web pages linked to each other, and these pages can be accessed and opened by visiting the main page of websites by a web browser, by typing the website address in the designated field in the browser, and in the event Not knowing the address, so one of the search engines (English: Search Engines) can be used to find out .

[6]

Hypertext markup language

HyperText Markup Language, which is abbreviated as "HTML", is a set of symbols and tags that are written in a file to explain to the browser how to display it to the page and what it contains of images and writings as required. Each text in the file forms an element on the page . [7]
