The following outline is provided as an overview of and topical guide to information technology:

Information technology (IT) microelectronics based combination of computing and telecommunications technology to treat information, including in the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information. It is defined by the Information Technology Association of America (ITAA) as "the study, design, development, implementation, support or management of computer-based information systems, particularly toward software applications and computer hardware."
