Information technology allows data to be processed, stored and transmitted.
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 specific to computing, electronics and telecommunications.
It is important to note that the idea of information technology emerged in the mid- 20th century . However, humans were already storing, processing and transmitting information several millennia before Christ. These processes, of course, were very different from the current ones.
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 early computing have been overcome, such as device dimensions, processing speed, and memory volatility (early storage media were incapable of retaining data once interrupted. the supply of electrical energy, as is the case with RAM memory), but there are still many pending challenges, the stability of the Internet being one of the main ones, without leaving aside 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 areas, from academic to work, including leisure and interpersonal communications.
Computers occupy a central role in information technology.
Information technology in companies and everyday life
Most companies today make constant use of information technology. Take the case of a clothing store that has a website where it presents data on its products and also uses email to contact its customers and suppliers. At the premises, a computer allows operations to be recorded and invoices issued to buyers. Stock movements are also recorded on the computer.
Many people also use information technology in everyday life, communicating by email, chat or telephone; watching television to inform yourself; and using video game consoles as entertainment, to name just a few activities.
Professionals in area management
One of the most popular jobs today is Information Technology Service Management , which comes from the 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 to that of our language).
A professional in this field is expected to have acquired the necessary knowledge to design, develop, apply and maintain computer information systems , in addition to being able to provide support to other employees of the company in which they work. This is a complementary role, for example, to that of programmers, since they are in charge of installing and maintaining all the programs used in the company, managing and repairing networks, and updating devices.
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 goes into action; Likewise, you must assist your colleagues to solve software and hardware problems, replace defective parts, design and implement the network structure to provide all employees with Internet and intranet connections, and even write small programs. computer programs that serve to speed up certain processes and thus avoid the need to work on each particular computer.
