The concept of information technology refers to the use of telecommunications equipment and computers (computers) for the transmission, processing and storage of data. The notion covers specific topics of computing, electronics and telecommunications.
It is important to note that the idea of information technology emerged in the middle of the 20th century. However, the human being already stored, processed and transmitted information several millennia before Christ. These processes, of course, were very different from today. Throughout history, the need to store and disseminate information has become increasingly important and today they are basic issues for the development of human life. Many of the limitations of the early days of computing were overcome, such as device dimensions, processing speed, and memory volatility (early storage media could not retain data once stopped). Electricity supply as well as RAM memory), but there are still many pending challenges, being the stability of the Internet one of the main ones, without neglecting the abysmal differences between providers of developed and underdeveloped countries.
This makes the notion associated with computers, although it also includes other devices such as televisions, phones and tablets. Today, information technologies are essential in a large number of fields, from academics to work, through leisure and interpersonal communication.

It is expected that a professional in the area has acquired the necessary knowledge to design, develop, apply and maintain computer systems, in addition to being able to support the other employees of the company in which they work. It is a complementary function, for example, to that of programmers, since it is responsible for installing and maintaining all the programs used in the company, managing and repairing networks and updating devices. Whenever it is necessary to install or update the operating system, antivirus or any of the company’s programs, the person in charge of IT Management intervenes; You must also assist your colleagues in solving software and hardware problems, take care of the replacement of defective parts, design and implement the network structure to provide all employees with Internet and intranet connections, and even write small computer programs. that comply with streamlining certain processes and thus avoid having to work on each particular team.
