IT - Information Technology

IT is short for Information Technology and is pronounced as separate letters. Information technology is the broad subject concerned with all aspects of managing and processing information, especially within a large organization or company. IT is generally not used in reference to personal or home computing and networking.

IT is More than Computers and Networks

While IT is often used to describe computers and computer networks, it actually includes all layers of all systems within an organization — from the physical hardware to the operating systems, applications, databases, storage, servers and more. Telecommunication technologies, including Internet and business phones are also part of an organization's IT infrastructure.
