  3. 4. <ul><li>A computer case is the enclousure that contains most of the components of a computer. </li></ul>
  4. 5. <ul><li>A power supply unit , supplies direct current (DC) power to the other components in a computer. It converts general-purpose alternating current (AC) electric power from the mains to low-voltage DC power for the internal components of the computer. </li></ul>
  5. 6. <ul><li>A motherboard is the central printed circuit board in many modern computers and holds many of the crucial components of the system. </li></ul>
  6. 7. <ul><li>The central processing unit (processor) is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. </li></ul>
  7. 8. <ul><li>Memory (Random Access Memory) is a form of computer data storage. It takes the form of integrated circuits that allow stored data to be accessed in any order with a worst case performance of constant time. </li></ul>
  8. 9. <ul><li>A video card is an expansion card which generates output images to display. </li></ul>
  9. 10. <ul><li>A hard drive is a non-volatile, random access digital magnetic data storage device. </li></ul>
