Often whenever the words ‘information technology’ is used, it is believed to be the whole industry. Information technology essentially refers to the employment of pc hardware and software programs to control data. Business units, such as Management Information Services (MIS), take care of the responsibility for the storage, protection, processing, transmission and retrieval of the information as required.
Information technology, although it brings about thoughts and visions of networks, the Internet, server rooms, racks of switches and routers, as well as advanced terms including VoIP, TCP/IP addressing, security and more, the ‘technology’ doesn’t automatically refer only to computer associated issues. Any kind of medium or channel which stores and processes information makes its way into the category of information technology. The human brain is an information processor, working to process and manage information which regulates our every movement, body functions, and habits. Whichever process or attempt to communicate, store and manage information as well as utilize and administer that data will fall under the classification.
The history of information technology precedes the invention of the computer. The abacus, used by Asians, Egyptians, Romans, and the Greek can be called a source of information technology. Calculators, the first mechanical one built by German polymath Wilhelm Schickard, or even the slide rule, developed in 1622 by William Oughtred, all come under the heading of information technology. An additional example would be punch card machines, expanded upon by IBM in the early to mid 1900’s, qualifies the term information technology.
As time has progressed along with the advances of inventions and applied knowledge, computing took shape and grew to become useful in a variety of ways other than calculations. Computer science evolved into an academic specialty, creating computer science departments and classes. As these classes took shape, independent divisions of computer science became distinct areas of study. These days, Information Technology departments use computers, data centers, servers, database management system, specialized software applications and more, managed by system and database administrators, an Information Technology Manager and other department heads, including a Chief Information Officer (CIO). Although information technology has a long span into history, only recently has it become associated with the use of computers.
