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 issues of information technology, electronics and telecommunications.
Importantly, the idea of information technology emerged in the mid-twentieth century. However, the human being already stored, processed and transmitted information several millennia before Christ. These processes, of course, were very different from the current ones.
Throughout history, the need to store and propagate information has become increasingly important, and today they are basic issues for the development of human life. Many of the limitations of the early periods of computing have been overcome, such as the dimensions of the devices, the processing speed and the volatility of memory (the first storage media were unable to retain the data once it was interrupted the supply of electricity, as is the case with RAM), but there are still many challenges pending, with Internet stability being one of the main ones, without neglecting the abysmal differences between providers in developed countries compared to underdeveloped ones.
This makes the notion associated with computers, although it also includes other devices such as televisions, phones and tablets. Today, information technology is indispensable in a large number of fields, from academic to work, through leisure and interpersonal communications.
Most companies today use information technology constantly. Take the case of a clothing store that has a website where it presents data of its products and also uses email to contact its customers and suppliers. On the premises, a computer allows you to record the operations and issue the invoices delivered to the buyers. In addition, stock movements are recorded on the computer.
Information technology Many people also appeal to information technology in everyday life, communicating by email, chat or telephone; watching television for information; and using video game consoles as entertainment, to name just a few activities.
One of the most popular jobs today is Information Technology Service Management, which comes from English Information Technology Service Management, and is generally known as IT Management, even in Spanish-speaking countries ( Note that the acronym for “information technology” in English is written with the letters in the opposite order of our language).
It is expected that a professional in this field has acquired the necessary knowledge to design, develop, apply and maintain computer information systems, in addition to being able to support the other employees of the company in which he works. This is a complementary role, for example, to that of programmers, since it is responsible for 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.
Whenever the operating system, antivirus or any of the company’s programs must be installed or updated, the person responsible for IT Management takes action; Similarly, you must assist your colleagues to solve software and hardware problems, replace defective parts, design and implement the structure of the networks to supply all employees of Internet and intranet connection, and even write small programs information that serve to speed up certain processes and thus avoid the need to work on each particular computer.
