History of Information Technology

The backstory of information technology precedes the invention of the computer. The abacus, used by Asians, Egyptians, Romans, and the Greek can be termed a source of information technology. Calculators, the first mechanical one built by German polymath   Wilhelm Schickard, or the slide rule, developed in 1622   by William Oughtred, also comes under the heading of information technology. Another example would be punch card machines, expanded upon by IBM in the early to mid 1900's, qualifies the term information technology

.As time progress along with the advances of inventions and applied knowledge, computing took shape and became useful in a variety of ways other than calculations. Computer science became an academic specialty, creating computer science departments and classes. As these classes took shape, separate branches of computer science became distinct areas of study. Today, 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). Even though information technology has a long reach into history, only recently has it been associated with the use of computers.
