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.
Because computer systems are central to information management, computer departments within companies and universities are often called IT departments. Some companies refer to this department as IS (Information Services) or MIS (Management Information Services).
Information Technology Certifications and Jobs
IT spans such a broad subject there are many careers associated with IT. Information Technology certifications are designed to educate and objectively validate an IT professional's specialized competency in targeted areas of information technology. IT certifications can be obtained through education, experience or assessment of a specific set of knowledge skills. Today there are hundreds of certifications available through independent organizations and vendors.
