01. Basics of Computer Hardware

  1. 1.  Hardware  Software  Liveware
  2. 2.  System Unit  Central Processing Unit (CPU)  also called “The Chip”, “Microprocessor” or simply “The Processor”  Main Memory (RAM)  Storage Devices  Input Devices  Output Devices
  3. 3.  CPU or microprocessor is often described as the brain of a computer  CPU is an integrated circuit or “chip” which processes instructions and data.  CPU speed or CPU performance is measured by the completed Instruction Cycles Per Second (IPS).  Currently, CPU speeds range from 600 megahertz (MHz or million cycles per second) to 4 gigahertz (GHz or billion cycles per second).
  4. 4.  Processing performance of computers is increased by using multi-core processors, which essentially is plugging two or more individual processors (called cores in this sense) into one integrated circuit. (Eg: Intel Core i5, AMD Phenom II X4, …)
  5. 5. RAM or Random Access Memory  It is a volatile type of memory  Holds instructions for processing data, processed data, and raw data.  Ram is measured by:  Capacity (in Megabytes or Gigabytes)  Frequency (in MHz)
  6. 6.  Amount of RAM installed will determine. Which software applications will run (efficiently)? How many software applications can be open simultaneously? (multitasking ability)  Types of RAM: SRAM (Static RAM) DRAM (Dynamic RAM)
  7. 7.  Magnetic storage devices store data by magnetizing particles on a disk or tape.  Optical storage devices store data as light and dark spots on the disk surface.
  8. 8. Hard Disk Drives  Capacity is measured in gigabytes (GB or billions of bytes).  Typically permanently installed.  Used to store operating system, application software, utilities and data.  Magnetic storage device.
  9. 9. Other Storage Devices :  CD, DVD, BD…  External Hard Drives  USB Flash Drive (Pen drive orThumb drive)
  10. 10.  Input devices gather and translate data into a form the computer understands.  Primary input device:  Keyboard - Most common input device; used to type in commands and data.  Mouse or Trackball enhances user’s ability to input commands, manipulate text, images.  Touchpad orTouchscreen  Joystick useful for Gaming
  11. 11.  Scanners  Webcams  Microphones
  12. 12.  Monitors are the most commonly used output device. Most monitors use a bitmap (Raster) display.  Allows user to resize the display.  Divides the screen into a matrix of tiny square “dots” called pixels.  The more “dots” a screen can display, the higher the resolution of the monitor.  For example: CRT(Cathode RayTube), LCD (Liquid Crystal Display)…
