  1. 1. Lecturer: Muhammad WaqasE-mail:
  2. 2. Fundamentals of Information Technology seeks to provideyou with an understanding of the uses of computers. Thecourse additionally aims to endow you with practical skills ofusing a word processor, a spreadsheet, the Internet, and anoperating system, efficiently.
  3. 3. Introduction to computers and information technologyView the following pictures and formulate a definition of theterm „information technology‟.
  4. 4. Introduction to computers and information technology“Information Technology (IT), is the term used to describethe equipment, hardware and computer programs (software),that allows us to access... and present data and information(Gay and Blades, 2005).”Information Technology is the integration of variouscomputing tools used for information processing withintoday‟s society. It is mostly an adventure into how weconduct business and how we live our lives (Long, 2005).Additionally, we can view IT as a field of study in which welearn how best to remain competitive in society withinventions; as well as attain vocational and life-lasting skillsto use these inventions.
  5. 5. Introduction to computers and information technologyTechnically, a computer is any counting device; morespecifically, it is “ electronic device capable of interpreting and executing programmed commands for input, output, computation, and logic operations (Long, 2005).”Consequently, we can consider the computer system as a set of components that interact to achieve a common goal. The purpose, therefore, of a computer system is to use all its working components to produce quality information.
  6. 6. Introduction to computers and information technologyFor each of the following, highlight at least two means bywhich we use computers: Information systems/data processing systems Personal computing Science, research, and engineering Process/device control Education Entertainment Artificial Intelligence Speed Reliability Consistency Accuracy Storage Communication
  7. 7. Introduction to computers and information technologyA computer system has only four fundamental components: Input –handles the gathering of data Processing –transformation of data to information Output –handles the dissemination of processed data Storage –safe keeping of information for future useNote: The computer system (and not the computer) is made up of four components.
  8. 8. Introduction to computers and information technologyAn input device is any peripheral device that allows one to enter data or instructions into a computer.
  9. 9. Introduction to computers and information technologyAn output device is any peripheral device that conveys information to one or more individuals. Highlight three output devices that are commonly used today.
  10. 10. Introduction to computers and information technologyThe processor is the electronic component that interprets and carries out instructions to operate the computer system (which resides on the motherboard).
  11. 11. Introduction to computers and information technologyStorage components hold data, instruction, as well as information for future use; these items are kept on storage media (which are housed within the system unit).
