The answer to the above question lies in a fact the Security is an illusion. We can have optimal security measures but nothing in the world can guarantee you absolute protections. Logging with a user account Operating System limits the user from doing any changes that are of critical nature. This not only prevents the admin and his infrastructure from intentional malicious activities but also prevents from something that the user might commit un-intentionaly. " Users are considered the weakest link in security "  Hence if a user opens a file or a program that has been embedded  with some hidden stuff that attempts to run in background so as to perform data stealing/thieft/damage to critical processes causing DOS. The behavior of operating system of not allowing the regular user to perform any vital change will come to rescue. Hence it is a mitigation measure taken by admins and security professionals to keep their network safe from viruses, worms and malacious progr...

Ques What does seeding mean in torrent? Answer: The people sharing & connected to each other using the bit-torrent protocol are split into 2 categories. SEEDS (uppers) & LEECHERS (downloaders) In the begining while downloading a torrent for the first time you are a leecher because the download hasn't completed.
