MELJUN CORTES Computing Fundamentals - hardware

  1. 1. Computing Fundamentals Computer Hardware MELJUN P. CORTES
  2. 2. Objectives  Identify types of computers and how they process information  Identify the function of computer hardware components  Identify the factors to consider when buying computer equipment  Identify how to maintain computer equipment and solve common problems MELJUN P. CORTESBack
  3. 3. Introduction  When the computer was introduced, it’s said to be the greatest invention since man learned to use electricity.  Almost every aspect of peoples lives is affected in some way by computers.  Computers are no smarter than the humans who program them. MELJUN P. CORTESBack
  4. 4. Some ways in which the computer is used: • Word processing • Calculations • Communication • Computer-assisted learning • Research • Presentations • Database management • Automation • Entertainment MELJUN P. CORTESBack Next: Definition of Computer Computing
  5. 5. What is a computer? Computer is an electronic device that accepts, processes, stores, and outputs data at high speeds according to programmed instructions. There are two basic components that make up a computer: hardware and software. MELJUN P. CORTESBack Next: Parts of a Computer Computing
  6. 6. Parts of a Typical Computer System Unit Printer Monitor Keyboard Mouse MELJUN P. CORTESBack Next: Types of Computers Computing

  9. 9. The Four Main Components of a Microcomputer INPUT DEVICES Input devices allow us to enter information into the computer. They include keyboards, mice, scanners, and microphones. PROCESSING DEVICES Processing components manipulate the information once it is "in" the computer. In the microcomputer there is a set of common components consisting of the central processing unit (CPU), interface components, and memory (RAM). STORAGE DEVICES Storage devices store the entered information and programs for future use. Common storage devices include hard disks, floppy disks, and CD-ROMs. OUTPUT DEVICES Output devices are how the manipulated information is returned to us. They commonly include video monitors, printers, and speakers. MELJUN P. CORTESBack Parts of the System Unit Computing
