  1. Computer Applications Computer Applications

  2. Applications • Education • Public Services • Business and Commerce • Tele-Communications • Entertainment • Transportation • Expert System • Robotics Computer Applications

  3. Education(1) • Computer Assisted Learning (CAL) - in multimedia format to make learning more interesting - provide drills and practices for users to test their knowledge and get the result immediately • Web-Based Training (WBT) - the contents can be easily renewed, updated, and accumulated - use computers: facilitate learning - using Internet: access vast amounts of information Computer Applications

  4. Education (2) • Helps in School Administration • more efficient • process and complete tasks using computer makes the school run smoothly • Store large amount of data e.g. personal records, examination marks, time schedules and library book records Computer Applications

  5. Public Services • Allow us to seek information & obtain services conveniently Public information kiosk -provide information on nearby facilities in public places. -railway stations, shopping mall, etc. • Electronic public services -web sites contain information & services as esdlife -websites of the government e.g. info.gov.hk Computer Applications

  6. Business and Commerce(1) • Office Applications - helps office workers to simplify daily work. Examples: Word processor for producing documents, Spreadsheet for calculation. Office Automation (OA) & paperless office. • Intranets - promoting good communications and information exchange among staffs in a company. • Internet – provides communication and information exchange through the web. Computer Applications

  7. Business and Commerce(2) • Information Management Systems (IMS) - supports administration of a business organization.Examples may include Payroll system of an organization Point-of-sale system - helps operation during sale. Ticketing system - for booking tickets and facilities. • Electronic Transactions - for financial management such as Electronic funds transfer system (EFTS) Electronic money as Octopus E-banking and eCommerce On-line shopping as Amazon.com, auction as eBay. Computer Applications

  8. Tele-Communications • New way of working : telecommuting • Companies employ people working at home (SOHO: Small Office Home Office) • Staff use telecommunications as a tool to maintain contact with the office • Face2Face meeting w/ clients or colleagues using video-conferencing Documents E-mail / Fax / Internet Staff Clients or colleagues Computer Applications

  9. Entertainment • Playing computer games • Watching television and movie • Listening music • ICQ – online Chatting Computer Applications

  10. Transportation • Traffic Control • MTR • traffic light • Global Positioning System (GPS) • during war (e.g. Gulf War) • accident occur when hiking • microprocessor in car & other vehicles Computer Applications

  11. Expert System • Systems that simulates the decision-making processes of human experts or professionals • By searching through the rules and facts stored in the systems’knowledge bases • Examples include : Diagnosis of diseases, Language translation (also known as natural language processing) Computer Applications

  12. Robotics • It is a machine with artificial intelligence (AI). With the help of senses, it communicates with the environment and gives responses. • It can replace human to do dangerous or boring work such as car soldering. Thus, it saves manpower. • Robotic technologies are widely used in manufacturing industry • It may serve as a pet too, e.g. AIBO Computer Applications
