2.The Deep Web: The deep web is a subset of the Internet that is not indexed by the major search engines. This means that you have to visit those places directly instead of being able to search for them. So there aren’t directions to get there, but they’re waiting if you have an address. The Deep Web is largely there simply because the Internet is too large for search engines to cover completely. So the Deep Web is the long tail of what’s left out , like some company's database (as only specific people can access it or only some need these)[not to be confused for intranet , its another thing]

FOR ACCESSING

You will require exact address or URL as these pages are not indexed and can't be searched.
