DEFINITION OF INFORMATION TECHNOLOGY

Information Technology means the use of hardware, software, services, and supporting infrastructure to manage and deliver information using voice, data, and video. Information technology is also Set of tools, processes, and methodologies (such as coding/programming, data communications, data conversion, storage and retrieval, systems analysis and design, systems control) and associated equipment employed to collect, process, and present information.

 

 THE RELATIONSHIP BETWEEN INFORMATION TECHNOLOGY AN OTHER DISCIPLINES IN COMPUTING

 Computer Science is the study of computers, their design, and their uses for computation, data processing, and systems control, including design and development of computer hardware and software, and programming. The field encompasses theory, mathematical activities such as design and analysis of algorithms, performance studies of systems and their components, and estimation of reliability and availability of systems by probabilistic techniques. Because computer systems are often too large and complicated for failure or success of a design to be predicted without testing, experimentation is built into the development cycle.

 

 

  • Software engineering (SE) A systematic approach to the analysis, design, implementation and maintenance of software , and the study of these approaches; that is, the application of engineering to software. In layman’s terms, it is the act of using insights to conceive, model and scale a solution to a problem.

 

  • Information system (IS) is the study of complementary networks of hardware and software (see information technology) that people and organizations use to collect, filter, process, create, and distribute data. The study bridges business and computer science using the theoretical foundations of information and computation to study various business models and related algorithmic processes within a computer science discipline. Computer Information System(s) (CIS) is a field studying computers and algorithmic processes, including their principles, their software and hardware designs, their applications, and their impact on society while IS emphasizes functionality over design.

Data that approximates or characterizes but does not measure the attributes, characteristics, properties, etc., of a thing or phenomenon.
