In Computer science (informally: CS or compsci) is, in its most general sense, the study of computation and information processing, both in hardware and in software. Introduction Computer science encomposses a variety of topics relating to computation, ranging from abstract analysis of algorithms and formal grammars, to subjects like programming languages... computer science, interactive computing refers to Computer software (or simply software) refers to one or more computer programs and data held in the storage of a computer for some purpose. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another... software which accepts Information processsing In information processing, input is the process of receiving information from an object. The word input is used as a noun (information received or the process of receiving it) and less often as a verb (to receive information; or to enter information that a program then uses as... input from humans -- for example, A datum is a statement accepted at face value (a given). Data is the plural of datum. A large class of practically important statements are measurements or observations of a variable. Such statements may comprise numbers, words, or images. Etymology The word data is the plural of Latin datum, neuter... data or Command has multiple meanings: An order. In organizations, a command is an office or position of authority. In telecommunication, the term command has the following meanings: An order for an action to take place. In data transmission, an instruction sent by the primary station instructing a secondary station to perform... commands. Interactive software includes most popular programs, such as A word processor (also more formally known as a document preparation system) is a computer application used for the production (including composition, editing, formatting, and possibly printing) of any sort of viewable or printed material. They are descended from early text formatting tools (sometimes called text justification tools, from their... word processors or A spreadsheet is a rectangular table (or grid) of information, often financial information. (It is, therefore, a kind of matrix.) The word came from spread in its sense of a newspaper or magazine item (text and/or graphics) that covers two facing pages, extending across the center fold and treating... spreadsheet Application has the following meanings: In general, an application is using something general to some more conrete. For example: applied science. In business, an application is call for a job. In computing, application refers to a a software application. See also: application server This is a disambiguation page — a... applications. By comparison, noninteractive programs operate without human contact; examples of these include A compiler is a computer program that translates a computer program written in one computer language (called the source language) into an equivalent program written in another computer language (called the output or the target language). Introduction and history Most compilers translate source code written in a high level language... compilers and Batch processing is the sequential execution of a series of programs (jobs) on a computer. The term batch originated in the days when programmers wrote code on paper forms which would be keypunched onto 80-column punch cards or paper tape. The cards or tape would then be passed to... batch processing applications. If the response is complex enough it is said that the system is conducting social interaction and some systems try to achieve this through the implementation of social interfaces.

According to this view, Interactivity is the degree to which in a communication process each message is related to the previous messages exchanged (Rafaeli, 1988). This view defines three basic levels of interactivity: Non-Interactive - when... Interactivity
