Markup Languages are primarily used for what purpose?

Markup languages are specifically designed to annotate text and define its structure and formatting. They are utilized to delineate how data should be displayed, organized, and arranged on a webpage or within a document. For example, HTML (HyperText Markup Language) is a markup language that structures content for the web, enabling browsers to render the text, images, and other elements accordingly. This capability allows developers to focus on how information is presented rather than on the traditional programming logic associated with creating software applications.

The other options do not align with the fundamental purpose of markup languages. Data analysis typically involves processing and manipulating data using programming languages or data analytics tools, not markup languages. Compiling code into executable programs refers to the functionality of programming languages, which transform human-readable code into machine-readable code. Creating security protocols is a complex task that involves networking and system configuration, generally outside the scope of what markup languages are designed to do. Thus, the primary role of markup languages is indeed to express the formatting or arrangement of data.
