Q

Tor F
The information age is a true new age, based upon the interconnection of computers via telecommunications, with these information systems operating on both real-time and as-needed basis. Furthermore, the primary factors driving this new age forward are convenience and user-friendliness which, in turn, will create user-dependence. (James R. Messenger, Theory of Information Age, 1982)
