Information Technology department consisted of a single Computer Operator, who might be storing data on magnetic tape, and then putting it in a box down in the basement somewhere. The history of information technology is fascinating. Information technology is driven by the demands of the new, competitive business environment on the one hand and profound changes in the nature of computers in the other. IT systems come in the shape of many technologically advanced devices which help deliver important to managers who in turn, use this information to make crucial decision regarding the operations of their organization.
Information or Internet Technology can come in the form of computers, robots, sensors, and decision support systems. The newest form of Information & Technologies which is being implemented on the market today is the use of handholds to aid managers and subordinates in their day to day operations. Computer Technology Auditing (IT auditing) began as Electronic Data Process (EDP) Auditing and developed largely as a result of the rise in technology in accounting systems, the need for IT control and the impact of computers on the ability to perform attestation services.
IT is revolutionizing how business operates. Advanced technologies is becoming the single-most powerful force shaping the structure and functioning of work organizations, plants, offices, and executive suites. When people hear the words “Information & business technology,” the first thing that comes to their mind are computers and the Internet. It may also bring up words like “network,” “intranet,” “server,” “firewall,” “security,” as well as more arcane expressions such as “router,” “T-1,” “Ethernet,” or the mysterious and exotic-sounding “VOIP.” the term “Business IT” is not new and has not always referred to things relating to computer. Information technology is as old as the brain itself, if you think of the brain as an information processor. As far as IT being a science, even that goes back as far as the earliest attempts to communicate and store data. And that is essentially what information technology is: the communication and storage of information, along with the ability to process and make use of the information stored.
Information technologies is the use of computers and software to manage information. In some companies, this is referred to as Management Information Services (or MIS) or simply as Information Services (or IS). The information technology department of a large company would be responsible for storing information, protecting data, processing the techniques, transmitting the information as necessary, and later retrieving information as necessary. The benefits resulting from IT Technology benefits were in many different forms such as allowing all firms to accomplish tasks they had been doing before at reduced costs, it opened up possibilities to do things never attempted before, also allowed firms to “re-engineer” parts of their companies and make better strategic positions.
