Which of the following is a primary function of a browser?

A primary function of a browser is to access and render web pages. Browsers are designed to retrieve content from the internet, interpret the HTML, CSS, and JavaScript contained in web pages, and display that content in a way that is user-friendly. This involves not only fetching the data but also rendering it visually, allowing users to interact with the website seamlessly.

While executing programs on a network, managing local files, and configuring router settings are important tasks within the realm of technology, they fall outside the core capabilities of what a web browser is designed to do. A browser’s main purpose is specifically centered around accessing online content and providing a platform for users to navigate the internet effectively.
