What term describes a series of commands used to format, organize, and describe information on a web page?

The correct term that describes a series of commands used to format, organize, and describe information on a web page is "markup language." Markup languages are designed to annotate text so that the computer can understand its structure and formatting. In the context of web pages, HTML (Hypertext Markup Language) is the most commonly used markup language. It allows developers to create structured documents by using tags to define elements such as headings, paragraphs, links, and images.

Markup languages focus on the content's presentation and organization rather than performing calculations or logic, which distinguishes them from programming and scripting languages. For example, while a programming language is used to write algorithms and manage data, a markup language provides a way to organize and display that data in a comprehensible and visually appealing manner on the web.

In addition, styling languages, such as CSS (Cascading Style Sheets), are often used in conjunction with markup languages to control the visual presentation of the elements marked up in HTML. While scripting languages execute specific tasks and functions, their primary purpose is not to define the structure or format content but rather to enhance interactivity and functionality of web pages.
