Information technology (IT) is the application of computers and telecommunications equipment to store, retrieve, transmit and manipulate data, often in the context of a business or other enterprise.The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several industries are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, e-commerce and computer services.IT solution provider companies typically handle some part of another company’s IT landscape and vary dramatically in the scope of their work. These technology providers usually work with small to medium enterprises (SMEs) or with larger companies that have relatively light IT needs. For large enterprises, it is often cost effective to have all IT duties handled in-house, as the overhead cost is more spread out.
