Thats your internet history. Depending on the browser, there are ways to view the full history. Some browsers(or all?) once you start typing (ex: bleeping) it will pull up pages you've viewed from bleepingcomputer.com(and other sites if they have bleeping in the page title/domain).
It is recommended you clear your history and cache ever so often to help the performance of your PC, and incase you get issues with site not updating when they should.
If you'd like a easy way to access sites quickly, try bookmarks/favorites(depending on browser). They will allow you to save many sites for quick access at a later date.
