Hyper Text Markup Language (HTML).

Explanation:

Computers “communicate” with users and the Internet through programming languages, which can be described as sets of rules or commands for instructing a computing device to complete particular tasks. The examples of programming languages include HTML, JavaScript, Python, and PHP.

HTML is the standard and the most basic language for creating web pages. It was developed by Tim Berners-Lee in 1990. Every page on the Internet is written with some version of this programming language. Hyper Text in the name of this language refers to the process of linking objects to each other. Without HTML, a browser would not be able to display structured text or load images. A simple HTML code presented in the picture below.
