Any equipment or interconnected system(s) or subsystem(s) of equipment used in the automatic acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of data or information by the agency. For purposes of this definition, equipment is used by an agency if the equipment is used directly by the agency, or is used by a contractor under a contract with the agency that requires (1) its use or (2) to a significant extent, its use in the performance of a service or the furnishing of a product. The term "information technology" includes computers, ancillary equipment, software, firmware and similar procedures, services (including support services), and related resources, and does not include any equipment that is acquired by a contractor incidental to a contract; or contains imbedded information technology that is used as an integral part of the product, but the principal function of which is not the acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of data or information. For example, heating, ventilation, and air conditioning equipment, such as thermostats or temperature control devices, and medical equipment where information technology is integral to its operation, are not information technology.
