What is Linux

  Linux is an   open source operating system (OS) . It was originally conceived of and created as a hobby by Linus Torvalds   in 1991 . Linus, while at university, sought to create an alternative, free,   open source   version of the MINIX operating system, which was itself based on the principles and design of Unix.

Sites that end in “.onion,” for instance, can only be accessed anonymously and their web URL must be known in advance. Cybercriminals share such sites with each other and can reduce or eliminate unknown persons reaching their site accidentally via a Google search. Those who hold an online cybersecurity master’s degree know that the deep web is an enormous source of hacking knowledge and software. Studying hacking forums on the deep
