Information Technology (IT) is a term used to describe the equipment, specifically hardware and software, that enables us to access, retrieve, convert, store, organize, manipulate, and present data and information. It can also refer to the practical use of this equipment and software to generate information.
Computers are a fundamental element of information technology. A computer is defined as an electronic device that operates under the control of instructions stored in its memory. Whether used independently or connected through a network like the Internet, a computer performs four basic tasks: accepting data (input), manipulating data (processing), producing results (output), and storing data and results for future use (storage). These tasks together form the IPOS cycle.
The essential components of a computer are categorized as either hardware or software. Hardware constitutes the physical parts of the computer, while software consists of the computer programs that direct the hardware’s functions. Without software, the computer hardware would be inactive.
Information Technology integrates concepts from Computer Science, Information and Communications Technology (ICT), and Office Automation. Its scope encompasses the collection, processing, storage, retrieval, and dissemination of information, significantly impacting both professional activities and social life.
