What is Information technology (IT)
wikipedia.org- is the application of computers and telecommunications equipment to store, retrieve, transmit and manipulate data, often in the context of a business or other enterprise.
- A term that encompasses all forms of technology used to create, store, exchange and utilize information in its various forms including business data, conversations, still images, motion pictures and multimedia presentations .

Trivia
The term Information Technology (IT)
was coined by Jim Domsic of Michigan in November Domsic created the term to modernize the outdated phrase "data processing".
Computer programming or programming

5. Introduction to Information Technology
History of Information Technology
The basic concept of Information Technology can be traced to the World War II alliance of the military and industry in the development of electronics, computers, and information theory. After the 1940s, the military remained the major source of research and development funding for the expansion of automation to replace manpower with machine power.

Trivia
The term "computer", in use from the early 17th century
(the first known written reference dates from 1613), meant "one who computes": a person performing mathematical calculations, before electronic computers became commercially available.
Computer programming or programming

History of Information Technology
Since the 1950s, four generations of computers have evolved. Each generation reflected a change to hardware of decreased size but increased capabilities to control computer operations.
-First generation used vacuum tubes
-Second used transistors
-Third used integrated circuits
-Fourth used integrated circuits on a single computer chip.
Advances in artificial intelligence that will minimize the need for complex programming characterize the fifth generation of computers, still in the experimental stage.

History of Information Technology
The first commercial computer was the UNIVAC I, developed by John Eckert and John W. Mauchly in It was used by the Census Bureau to predict the outcome of the 1952 presidential election.
For the next twenty-five years, mainframe computers were used in large corporations to do calculations and manipulate large amounts of information stored in databases.
Supercomputers were used in science and engineering, for designing aircraft and nuclear reactors, and for predicting worldwide weather patterns.
Minicomputers came on to the scene in the early 1980s in small businesses, manufacturing plants, and factories.

Mainframe Computers vs Supercomputers
Mainframes deal with problems constrained by input/output and which demand reliability above all else. 
Mainframes process the large amounts of data that come into them from external sources, such as credit card transactions or payroll processing.
Supercomputers are designed to work on types of problems whose primary constraint is calculation speed. 
Supercomputers conduct large amounts of very fast and complex calculations on data stored in memory.
