What does a web browser do?

• A. It retrieves and displays content from the web
• B. It protects a computer from viruses
• C. It stores files and documents
• D. It manages network connections

Answer: (A)

A web browser is a software application specifically designed to retrieve, present, and navigate information on the internet. Its primary function is to request web pages from servers using the Hypertext Transfer Protocol (HTTP) and then render these pages so that users can view and interact with content, such as text, images, videos, and links.

This process involves translating the underlying code of web pages, such as HTML, CSS, and JavaScript, into a visual format that users can easily read and interact with. Therefore, the accurate description of what a web browser does is to retrieve and display content from the web.

The other options focus on functionalities that are not within the main scope of a web browser's purpose. For example, protecting a computer from viruses pertains more to antivirus software, while managing network connections is often handled by operating systems or dedicated network management tools. Storing files and documents typically refers to file management systems or cloud storage solutions, which serve different purposes than a web browser.
