What is a web feed?

A web feed is fundamentally a data format designed to deliver frequently updated content from websites to users in an efficient and standardized way. It allows users to subscribe to updates from various sources without having to visit each site individually. Common formats for web feeds include RSS (Really Simple Syndication) and Atom, which enable the automatic distribution of information such as blog posts, news articles, and other frequently changing content. This technology empowers users to aggregate content from multiple sources, streamlining their ability to stay informed about topics of interest.

The other options do not align with the definition of a web feed. Website navigation refers to how users interact and navigate through a website. A multimedia file pertains to audio, video, or other media formats, and an internet security measure involves practices designed to protect data and user privacy online.
