the concept of information technology refers to the use of telecommunications equipment and computers for the transmission, processing and storage of data. The notion covers issues of information technology, electronics and telecommunications.Information technologyIt is important to note that the idea of ?? ??information technology arose in the mid-twentieth century. However, the human being already stored, processed and transmitted information several millennia before Christ. Such processes, of course, were very different from the present ones.Throughout history, the need to store and propagate information has become increasingly important, and at present are basic issues for the development of human life. Many of the limitations of early computing have been overcome, such as device dimensions, processing speed, and memory volatility (the first storage media were unable to retain data once it was interrupted the supply of electrical energy, as it happens with RAM), but there are still many challenges still pending, with Internet stability being one of the main ones, without leaving aside the abysmal differences between the suppliers of developed countries and the underdeveloped ones.This makes the notion associated with computers, but also includes other devices such as televisions, phones and tablets. Today, information technology is indispensable in a large number of areas, from academic to work, through to leisure and interpersonal communications.Most companies today make use of information technology steadily. Take the case of a clothing store that has a website where it presents data of its products and also uses the email to contact its customers and suppliers. In the local, a computer allows to register the operations and to issue the invoices that they deliver to the buyers. The computer also records the stock movements.Information technologyMany people also appeal to information technology in everyday life, communicating by email, chat or phone; watching television for information; and using videogame consoles as entertainment, to mention just a few activities.One of the most popular jobs at the moment is Information Technology Service Management, which is usually referred to as IT Management, even in Spanish-speaking countries ( note that the acronym of “information technology” is written with letters in opposite order to that of our language).It is expected that a professional in this field has acquired the necessary knowledge to design, develop, implement and maintain computer information systems, in addition to being able to provide support to other employees of the company in which it performs. It is a complementary role, for example, to that of programmers, since it is in charge of the installation and maintenance of all the programs used in the company, the administration and repair of the networks and the updating of the devices.Every time the operating system, the antivirus or any of the company’s programs must be installed or updated, the person in charge of IT Management comes into action; Similarly, you must assist your colleagues in solving software and hardware problems, take care of replacing defective parts, designing and implementing the structure of the networks to supply all employees with Internet and intranet connections, and even write small programs computers that serve to streamline certain processes and thus avoid the need to work on each particular computer.
