Find out everything you need to know about IT or Information Technology. You will know all about the origins of IT, its modern definition and the different jobs related to this technology…
Very commonly used by English speakers, the term “Information Technology” shortened to “IT”; and refers to a wide variety of industries, trades and technologies. So much so that it is difficult to give a precise definition of “information technology”, which is often translated into French as “informatique”.
Actually, IT is omnipresent in our modern civilizationand perhaps represents its foundation, its engine and its cement. Information technology offers both countless opportunities and terrifying threats to humanity.
The origins of IT
The accepted definition of information technology is: “the study or use of systems (especially computers and telecommunications) for storing, retrieving and sending information”.
On the basis of this definition, it can be considered that the IT has emerged millennia ago. Already 65,000 years ago, humans were drawing on walls to keep track of their daily lives.
The appearance of the alphabet, of writing, is also part of this framework. In fact, information technology seems inextricably linked to the development of the alphabet. linked to human evolution and its thirst for progress….
IT has thus continued to develop throughout history.. In 1945, for the first time, a computer program was read by a computer. This enabled the exponential growth of information technology, with the tremendous advances that marked the next 50 years.
Other major events in the history of IT include the invention of Ethernet in 1973, the first personal computer in 1975, and, of course, the first computer in the world. the creation of the World Wide Web by CERN in 1993.
The emergence of the Internet and its availability to all is a real renaissance for information technology. The web has enabled this technology to become truly collective, and symbolizes the advent of the “information age”… .
Today, we would define information technology more as ” the use of computers and other physical devices of storage or networking, infrastructures and processes for creating, processing, storing, securing and exchanging all forms of electronic data”.
This modern definition includes all computer equipment and all the technologies and trades related to them. In the age of the Internet of Things, this also applies to the tens of billions of objects connected to the Internet.
However, it is possible to break down the IT world into six main areas The main areas of focus are: networking, cybersecurity, computers, programming, the World Wide Web, and computer support. These are the six distinct categories of information technology.
As it develops, IT gives rise to new professions necessary to create, install, maintain and protect all this technology. According to CompTIA’s Cyberstates Report 2018, 1.5 million IT jobs were created from 2010 to 2017 in the United States alone.
These include computer support technicians or networking experts, cybersecurity experts, computer systems analysts, programmers or web developers.
The demand is such that we are now deploring a real shortage of qualified professionals in the field of IT. The cybersecurity sector is particularly affected, with an estimated 3.5 million jobs to be filled worldwide by 2021. Salaries are attractive, but few individuals realize these career opportunities.
What is an IT department within a company?
Within a company, one generally finds an IT department or team. It is simply a team of IT professionals, responsible for using IT technologies to solve the problems faced by the organization.
L’IT team is responsible for the governance of computer systems, their operation and maintenance, and the management of the physical computer and hardware infrastructure. For example, team members will be responsible for security testing, maintaining the network, or installing equipment such as servers and PCs.
They must also helping other employees in the event of a technical problem. The best IT teams will be able to create processes and automate them in order to streamline the company’s operations.
Does the term “IT” still have a meaning in 2020?
To many people, the term “Information Technology”… no longer represents modern IT correctly and all its implications. However, it is now entrenched in morals and lexicons.
The definition of this term will continue to evolve to keep pace with innovation and technological change, but it will probably never go away. It is therefore important to understand its many facets and their subtleties.
