Int 2 computer structure 2010

  1. 1. Computer Structure Mr Arthur
  2. 2. Aims of Lesson 1 <ul><li>5 Box Diagram of a Computer System </li></ul><ul><li>Main Memory V Backing Storage </li></ul>
  3. 3. 5 Box Diagram
  4. 4. Main Memory <ul><li>Random Access Memory </li></ul><ul><ul><ul><li>Where programs are stored temporarily while the computer is on </li></ul></ul></ul><ul><ul><ul><li>Volatile Memory = The contents of RAM is lost when the computer is switched off </li></ul></ul></ul><ul><li>Read Only Memory </li></ul><ul><ul><li>The contents of ROM are stored permanently and cannot be edited </li></ul></ul><ul><ul><li>Programs are written to ROM during manufacture </li></ul></ul><ul><ul><li>Bootstrap Loader is stored in ROM and loads up the remainder of the OS </li></ul></ul><ul><li>The Main Memory is required to store parts of programs whilst in use by the processor </li></ul>
  5. 5. Lesson Starter <ul><li>I have an image that is 3 inches by 4 inches with a Resolution of 500dpi. Calculate the storage requirements. </li></ul><ul><li>What does RAM and ROM stand for? </li></ul><ul><li>What is the difference between RAM and ROM? </li></ul>
  6. 6. Aims of Lesson 2 <ul><li>Last Lesson </li></ul><ul><li>5 Box Diagram of a Computer System </li></ul><ul><li>Main Memory V Backing Storage </li></ul><ul><li>Today’s Lesson </li></ul><ul><li>Backing Storage </li></ul><ul><ul><li>Magnetic </li></ul></ul><ul><ul><li>Optical </li></ul></ul><ul><ul><li>Serial Access </li></ul></ul><ul><ul><li>Direct Access </li></ul></ul>
  7. 7. Backing Storage <ul><li>A Backing Storage device is a piece of hardware that is used to store data permanently when the computer is switched off </li></ul><ul><li>Magnetic </li></ul><ul><ul><li>Hard Disk </li></ul></ul><ul><ul><li>Magnetic Tape </li></ul></ul><ul><ul><li>USB Memory Stick </li></ul></ul><ul><li>Optical </li></ul><ul><ul><li>CDROM/R/RW </li></ul></ul><ul><ul><li>DVDROM/R/RW </li></ul></ul><ul><li>Sequential Access = This is Backing Storage where you access data in a particular order </li></ul><ul><li>Direct Access = This Backing Storage allows you to access data in any order </li></ul>
  8. 8. Lesson Starter <ul><li>What is the purpose of Backing Storage? </li></ul><ul><li>List 4 examples of Backing Storage devices </li></ul><ul><li>What is the difference between Sequential and Direct data access? </li></ul>
  9. 9. Aims of Lesson 3 <ul><li>Last Lesson </li></ul><ul><li>5 Box Diagram of a Computer System </li></ul><ul><li>Main Memory </li></ul><ul><li>Backing Storage </li></ul><ul><li>Today’s Lesson </li></ul><ul><li>The Processor </li></ul>
  10. 10. Lesson Starter <ul><li>What is the purpose of purpose of the processor? </li></ul><ul><li>What is the measure of processor speed? </li></ul>
  11. 11. The Processor <ul><li>The processor or C entral P rocessing U nit is the brain of the computer where all the decision making, calculations etc are carried out </li></ul><ul><li>We send instructions (programs) to the processor to get the computer to do something </li></ul><ul><li>Processor speed (clock speed) is measure in how many millions of instructions the processor can process per second (typically 3-4Ghz) </li></ul><ul><li>Clock speed is one of the main measures of computer performance </li></ul>
  12. 12. Parts of the Processor <ul><li>Control Unit </li></ul><ul><ul><li>Manages the fetching and executing of programs held in RAM </li></ul></ul><ul><ul><li>Makes sure programs are processed in the correct order </li></ul></ul><ul><li>Arithmetic Logic Unit </li></ul><ul><ul><li>Performs + - X / calculations </li></ul></ul><ul><ul><li>Makes AND, OR, NOT and IF decisions </li></ul></ul><ul><ul><li>Handles FOR, loop untils </li></ul></ul><ul><li>Registers </li></ul><ul><ul><li>Storage locations on the processor chip to temporarily store instructions </li></ul></ul>
  13. 13. Lesson Starter <ul><li>List the 3 parts of the processor </li></ul><ul><li>Which part of the processor makes sure programs are processed in the correct order and manages the timing of processing? </li></ul>
  14. 14. Computer Comparison EMBEDDED SYSTEM = A processor inside another device, for example, a microwave, sky + box. Type RAM Hard Disk Processor Peripherals Palmtop 256Mb 1Gb (Solid State) 500-800MHz Stylus Touch Sensitive Monitor Laptop 3Gb RAM 320GB 2.2 GHz possibly dual core Touch Pad LCD/TFT Monitor Desktop 4Gb RAM 500Gb 3.2Ghz possibly quad core Mouse, Keyboard, LCD Monitor Mainframe Approx 32Gb RAM 8Tb or more 3.2Ghz possible 16 processors or more
