Information
Information is any entity or form that provides the answer to a question of some kind or resolves uncertainty. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
Information Technology
Information technology (IT) is the use of computers to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise. IT is considered to be a subset of information and communications technology (ICT).
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
Technology
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is first robustly defined by Jacob Bigelow in 1829 as: "...principles, processes, and nomenclatures of the more conspicuous arts, particularly those which involve applications of science, and which may be considered useful, by promoting the benefit of society, together with the emolument [compensation ] of those who pursue them" .

Vannevar Bush is a great name for playing six degrees of separation. Turn back the clock on any aspect of information technology — from the birth of Silicon Valley and the marriage of science and the military to the advent of the World Wide Web — and you find his footprints. As historian Michael Sherry says, "To understand the world of Bill Gates and Bill Clinton, start with understanding Vannevar Bush."
G. Pascal Zachary, in "The Godfather" in WIRED 5.11 (November 1997).
Management
Management is defined here as the accomplishment of desired objectives by establishing an environment favorable to performance by people operating in organized groups. Each of the managerial functions (planning, organizing, staffing, , directing, and controlling) is analyzed and described in a systematic way. As this is done, both the distilled experience of practicing managers and the findings of scholars are presented. This is approached in such a way that the reader may grasp the relationships between each of the functions, obtain a clear view of the major principles underlying them.
