Description: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," "security," as well as more arcane expressions such
as "router," "T-1," "Ethernet," or the mysterious and exotic-sounding "VoIP"
(pronounced "voyp").
In fact, 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.
And that is essentially what information technology is: the communication and
storage of information, along with the ability to process and make use of the
information stored. In this chapter, we'll begin with a brief history of I.T., what it
comprises today, and the different major types of I.T. systems availablehttps://www.videosprofitnetwork.com/watch.xml?key=1701c9edf35c9757e07125af760f8014
