IT Essentials & Data Recovery For Online Businesses  (English, Paperback, Nishant Baxi)

When people hear the words "Information Technology," the first things that come to mind are computers and the Internet. It may also bring up words like "network," "intranet," "server," "firewall," and "security," as well as more arcane expressions such as "router," "T-1," "Ethernet," or the mysterious and exotic-sounding "VoIP" (pronounced "voyp"). Information technology is all of these things, and more. It's hardly new, however. Information technology is as old as the brain itself if you think of the brain as an information processor. As far as I.T. being a science, even that goes back as far as the earliest attempts to communicate and store information.
