  1. 1. COMPUTER HARDWARE
  2. 2. WHAT IS COMPUTER HARDWARE? <ul><li>Refers to the physical and mechanical components of the computer system. </li></ul><ul><li>It consists of devices such as: </li></ul><ul><li>circuit boards </li></ul><ul><li>chips </li></ul><ul><li>Monitors </li></ul><ul><li>Disks </li></ul><ul><li>Disk drives </li></ul><ul><li>Modem </li></ul><ul><li>Keyboards </li></ul><ul><li>Printers </li></ul>
  3. 3. EVOLUTION OF COMPUTER HARDWARE
  4. 4. MECHANICAL CALCULATOR <ul><li>made by Wilhelm Schickard. </li></ul><ul><li>used cogs and gears similar to those in clocks . </li></ul>
  5. 5. PUNCH CARD TECHNOLOGY
  6. 6. ELECTRONIC NUMERICAL INTEGRATOR ANALYZER AND COMPUTER(ENIAC) <ul><li>designed by John Presper and John William Mauchly. </li></ul><ul><li>it was built by the US Army in 1945 to calculate the trajectory of ballistic missiles, at a cost of almost $500,000. </li></ul>
  7. 7. FUNCTIONS OF COMPUTER HARDWARE
  8. 8. STORAGE <ul><li>Refers to the ability of computer to store and retain data in their memories </li></ul><ul><li>Types of Memory </li></ul><ul><li>Volatile memory - refers to computer memory that requires electric power to maintain stored data. </li></ul><ul><li>ex. Random-access memory (RAM) </li></ul><ul><li>2. Non-volatile memory – retains data even if electric is cut off. </li></ul><ul><li>ex. hard disks, floppy disks, and CD ROMs </li></ul>
  9. 9. PROCESS <ul><li>Data processing - Is defined as the conversion of data from one format to another </li></ul><ul><li>DATA – refers to a collection of numbers and characters which the computer understands. </li></ul><ul><li>MICROPROCESSOR – brain of the computer </li></ul><ul><ul><ul><li>controls the flow of data – Central processing unit (CPU) </li></ul></ul></ul>
  10. 10. METHOD OF PROCESSING <ul><li>Parallel Processing - harnesses the power multiple processors in one computing entity to perform a single task. </li></ul><ul><li>Distributed Processing - is used to bind multiple computing entity so that they become a single centralized unit focused on common task or goal. </li></ul>
  11. 11. INPUT <ul><li>computer hardware can take commands and be fed with information </li></ul><ul><li>Input Devices </li></ul><ul><li>Keyboard </li></ul><ul><li>Mouse </li></ul><ul><li>Trackball </li></ul><ul><li>touch pad </li></ul><ul><li>Joystick </li></ul><ul><li>graphic tablet </li></ul><ul><li>light pen </li></ul><ul><li>cyber gloves </li></ul><ul><li>touch screen </li></ul>
  12. 12. OUTPUT <ul><li>ways for computers to communicate to the outside world, beginning with you. </li></ul><ul><li>Output Devices </li></ul><ul><li>Monitor or screen </li></ul><ul><li>Speaker </li></ul><ul><li>printer </li></ul>
  13. 13. PARTS OF THE COMPUTER
  14. 14. MONITOR <ul><li>screen that displays what is going on in the computer. </li></ul>
  15. 15. KEYBOARD <ul><li>Used to input textual information to the computer </li></ul>
  16. 16. MOUSE <ul><li>lets you feeds instructions to the computer by simply pointing and clicking in a graphical environment </li></ul>
  17. 17. SYSTEM CASE <ul><li>box that house the CPU. </li></ul><ul><li>It has expansion slots contains spare drive bays, and allows space to work inside for attachments to the system unit. </li></ul>
  18. 18. MOTHERBOARD <ul><li>main circuit board in the computer. </li></ul><ul><li>Its chipset must support the kind of hardware you want with your system. </li></ul>
  19. 19. MAIN MEMORY/RAM <ul><li>allows computers to store and retain information. </li></ul>
  20. 20. PROCESSOR <ul><li>brain of the computer that handles the flow of all data. </li></ul>
  21. 21. HARD DISK <ul><li>storage device that holds the operating system and other programs and data files. </li></ul>
  22. 22. FLOPPY DISK DRIVE <ul><li>Perhaps the slowest form of long term secondary storage for the computer is the floppy disk with 1.44 MB disk drive. </li></ul>
  23. 23. CD-ROM/DVD-ROM DRIVE <ul><li>reads CDs or DVDs. </li></ul>
  24. 24. VIDEO/GRAPHICS CARD <ul><li>most graphics cards today have at least 32 MB. </li></ul><ul><li>Using a card that has less might cause problems with the computer you are building because many programs that use heavy graphics will not work. </li></ul>
  25. 25. SOUND CARD <ul><li>converts data into sound to be sent to speakers or converts sounds to digital formats. </li></ul>
  26. 26. CABLE CONNECTORS <ul><li>computer parts cannot come together by themselves. </li></ul>
  27. 27. OTHER PERIPHERALS <ul><li>optional devices that you connect to your computer, like printers and removable storage devices. </li></ul>
