Web feed
On the World Wide Web, a web feed (news feed, syndicated feed) is a data format used for providing users with frequently updated content.
Description
Content distributors syndicate a web feed, thereby allowing users to subscribe to it.
Making a collection of web feeds accessible in one spot is known as aggregation, which is performed by a news aggregator.
A typical scenario of web-feed use might involve the following:
A content provider publishes a feed link on its site which end users can register with a news aggregator program (also called a feed reader or a news reader) running on their own machines; doing this is usually as simple as dragging the link from the web browser to the aggregator. When instructed, the aggregator asks all the servers in its feed list if they have new content; if so, the aggregator either makes a note of the new content or downloads it. One can schedule aggregators to check for new content periodically.
Web feeds exemplify pull technology, although they may appear to push content to the user.
The kinds of content delivered by a web feed are typically HTML (webpage content) or links to webpages and other kinds of digital media. Often when websites provide web feeds to notify users of content updates, they only include summaries in the web feed rather than the full content itself.
Many news websites, weblogs, schools, and podcasters operate web feeds.
