Bookmarks are web browsers' way to allow users to store frequently accessed links or URLs they want to save for later analysis.
In Internet Explorer, they are called Favorites or Internet shortcuts, and these terms have been adopted by other browsers as well.
Bookmark managers are software applications that enable easier access to the stored links and feature sorting options.
However, nowadays, most browsers already provide these functions so bookmark managers are used mainly for converting items between various formats compatible with specific browsers.
