Home | IT - Term Overview

The concept of IT - information technology - refers to the use of telecommunications equipment and computers for the transmission, processing and storage of data. The notion covers issues specific to computing, electronics and telecommunications.

It's important to note that the idea of ‚Äč‚Äčinformation technology emerged in the mid- 20th century. However, human beings 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 days of computing have been overcome, such as device dimensions, processing speed, and memory volatility (early storage media were unable to retain data once it was interrupted). electricity supply, as well as RAM memory), but there are still many pending challenges, with the stability of the Internet being one of the main ones, without neglecting the abysmal differences between suppliers from 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 of today's companies make use of information technology constantly. Take the case of a clothing store that has a website where it presents data on its products and, in addition, uses email to contact its customers and suppliers. On the premises, a computer allows operations to be recorded and the invoices issued to buyers. The computer also records the stock movements.

Many people also make use of 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.

It's 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 provide support to the other employees of the company in which he works. It's a complementary role, for example, to that of programmers, since it's 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, antivirus or any of the company's programs must be installed or updated, the person responsible for IT Management takes action; in the same way, he must assist his colleagues to solve software and hardware problems, take care of replacing defective parts, design and implement the structure of the networks to supply all employees with Internet and intranet connection, and even write small programs computer that serve to streamline certain processes and thus avoid the need to work on each computer in particular.
