| What is information technology (IT) |
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 spread information has become increasingly important, and today they are basic questions 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 it happens with 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 versus 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 essential in a large number of fields, from academic to work, through leisure and interpersonal communications.
Most companies today make constant use of information technology. Let's 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. On the premises, a computer allows to record the operations and issue the invoices that they deliver to the buyers. Stock movements are also recorded on the computer.
Many people also appeal to information technology in everyday life, communicating by email, chat, or phone; watching television for information; and using video game consoles for entertainment, to name just a few activities.
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).
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 provide support to the other employees of the company in which he works. This is a complementary role, for example, to that of the programmers, since they are in charge of the installation and maintenance of all the programs used in the company, the administration and repair of networks and the updating of devices.
Every time the operating system, antivirus or one of the company's programs must be installed or updated, the person responsible for IT Management takes action; likewise, you must assist your colleagues in solving software and hardware problems, take care of replacing faulty parts, design and implement the structure of networks to supply all employees with Internet and intranet connections, and even write small programs. Computer systems that serve to streamline certain processes and thus avoid the need to work on each individual computer.
