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

The importance of data storage and dissemination
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). electrical power supply, as well as memory RAM), but there are still many pending challenges, the stability of the Internet being one of the main ones, without neglecting the abysmal differences between providers from developed countries compared to underdeveloped ones.

Every time the operating system, the 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 science that serve to streamline certain processes and thus avoid the need to work on each computer in particular.
