By and large, deep web are ordinary Internet pages. Their main difference from the sites available to you is only that they are not indexed by search engines and they are not hyperlinked from public resources.
Unlike darknet, it is possible to access deep web pages using a standard browser, but for this you need to have a direct link to the resource. And these links, unlike the usual ones, often contain a large number of random alphanumeric characters, which complicate the selection of the address.
Most deep web resources are information that is not intended for wide use, such as archives of companies and government agencies, catalogs, database access services, libraries, and the like.
Darknet or Onion networks are no longer accessible without the use of special software, such as the Tor browser. They provide anonymity to both services running on that subnet and users.
That is why the darknet sells stolen files, leaked user bases, illegal software, and other things that can get you into trouble on a regular network.
There are also no copyright holders in the Onion network - therefore, piracy there has reached “a modern new level”. If you have ever encountered the situation of deleting a digital file “at the request of the copyright holder”, be sure that this file is absolutely freely available on the darknet.
I think that you should study the information about dark web links and it will be useful for you. I hope that you will use my advice.
