Information Technology has come a long way, and it's history is quite fascinating. It is the use of computers and software to manage information. Certain corporate settings call this Management Information Services (MIS), or simply Information Services (IS).
Commonly, the Information Technology department of an organization would store information, protect data, process the techniques, and then transmit the information as required, for later retrieval if and when required.
Information Technology has yielded unbelievable benefits like the wholesale accomplishment of tasks at tremendously reduced costs, a new ability to do things that had never been attempted before, and the re-structuring of parts of companies to assume a more profitable and better overall strategic status.
In the past, the Information Technology department of an organization would have only one computer operator who would load all data on a magnetic tape, and then store this safely down in the basement. All these has changed, largely because of the demands of an aggressively competitive business environment on the one hand, and revolutionary changes in computers in recent years on the other. IT systems now appear in the sophisticated forms that deliver crucial information to corporate managers, who in turn use this information to arrive at crucial decisions that affect the running of their organizations.
While computers, robots, sensors and decision support systems have been around for some time, the newest forms of Information Technology devices are hand-held devices that aid corporate managers in their daily operations.
An instance of these remarkable changes is seen in accounting systems, in which the need for greater IT control and computer aided-attestation control has led to progress from Electronic Data Process (EDP) Auditing to Computer Technology (IT) Auditing.
