As presented by our Instructor Colette Gardner, information systems and information technology are an essential part within all aspects of a company's structure and to all business types. Although used interchangeably Information Systems (IS) and Information Technology (IT) serve as different functions within a company. Information systems is a large umbrella referring to systems that collect, processes, stores, analyzes, and disseminates information for a specific purpose. Whereas, information technology deals with the technology involved in the systems themselves, (e.g. information system like wiki.answers.com contains many information technologies) In addition to defining and understanding various computer terminologies, Intro to Computer Applications and Systems Class will guide us through understanding the various management styles and strategies used when referring to computers and computer technology, how they apply to each level of an organization, the different computer interfaces and how they are all connected, and the various roles of the information system, department and end users.
