GuruIntroduction
Information Technology (IT) refers to managing and using information through computer-based tools, including both hardware and software. People mostly use the term for business applications of computer technology rather than scientific ones. IT has potential in every sector of the economy. In many developed economies, IT has been a dynamic sector, and India stands out as a developing country where the IT sector has grown rapidly. In India, bright and innovative individuals often choose IT jobs as their first career choice.
History of information technology
The back-story 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.
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.
Conclusion
Recall that IT engineering is a broad area with several subspecialties, so search through all of them if this field really interests you. A successful career in the field of IT engineering requires continuous learning and adaptation to new technologies.
