Information technology (IT) can be defined in various ways, but is broadly considered to encompass the use of computers and telecommunications equipment to store, retrieve, transmit and manipulate data. The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones.
In 3000 BC, the Sumerians in Mesopotamia were the first to develop the writing. This was the first tryst of human beings with storing, manipulating and communicating information. In purview of today’s meaning of Information technology, it appeared in the modern sense in 1958in an article that was published by Harvard Business Review.
The Information technology has been growing and developing from four basic phases. They are: pre mechanical, mechanical, electro mechanical and electronic. In simple jargon, information technology can be stated as management of computer based information systems.
Even in the pre historic era, when man thought exchanging a stone for wheat made complete sense, they used to keep count of things using sticks and stone. Man was always pressed for information and used various means to understand, identify, store and revive this information. For many a thousand years, various devices have been used to aid computation. From the earliest tally sticks to today’s tablets, information technology has grown. The earliest known mechanical analog computer- Antikythera mechanism was also the earliest known geared mechanism. There was no turning back to information technology and it has grown manifold from databases, data storage, data retrieval, data transmission and data manipulation.
The worldwide spending in information technology has grown to a staggering 3,628 billion U.S dollars. Every company- partnership, joint venture, every type of industry- agriculture, retail and just anybody from a start up to a multinational makes use of information technology to connect, communicate and collaborate.
Technology before made use of punched tapes that were long and striped and were represented by a series of holes. Today with wireless solutions and cloud computing coming in, such technology is obsolete. During the second world war, electronic data storage was used in modern computers. Then A Williams tube based on standard cathode ray tube, but the information had to be continuously refreshed due to presence of volatile memory and tended to be lost once power was gone. This is a far cry from today’s scenario where even if you forget to take a backup a device can retrieve your unsaved texts as most digital data is stored magnetically on hard disk drives and the capacity worldwide to store information ha only being doubling .
Thus, information technology today is beyond computers or electronic tools. It is the way of life. It is all about communicating in real time and making sense of the data to fulfill purposes for larger good of the society. It has become an indispensable part of one’s lifestyle. A person who is not technology savvy is a rarity in today’s fast paced globalized era. The one thing that is driving the information technology to take leaps and bounds is: communication.
