IT (information technology) is a broad term for a variety of subjects based around computing. The main purpose of IT lessons is to teach students how to utilize modern tech effectively both at work and in their day to day lives. IT is often used to maximize efficiency and to innovate.
The core reason why IT is such an essential subject is because computing influences so many aspects of our modern lives. Both children and adults need to know the basics of IT, if they wish to participate in a rapidly evolving, increasingly tech-centric society.
A large number of careers also require employees to have IT skills in order to complete their tasks effectively. IT qualifications are often a key job skill. This is why coding has become much more prevalent in school curriculums. In the past, knowing computer languages was seen as a specialist subject. However, today it tends to be considered a vital qualification.
IT also encompasses more broad parts of daily life outside of work. Most people today communicate through text messaging and email services. They get their news from online sources. A large number of recreational activities such as gaming and streaming involve information technology. The more a person understands the subject the better they will be at utilizing everyday technological tools.
