Q: What is information technology?

Information technology (IT) is the use of computers to store and transmit data. Mostly, IT is referred to in business or enterprise contexts. The larger branch of which IT is a part of, is information and communications technology (ICT).

IT systems, and hence IT companies, are at the heart of the tech revolution our world has witnessed in the past few decades.
