  1. Unit 3 Inside the system

  2. Three tasks What are on a motherboard? Get your hands dirty! Install a DIMM memory module (without breaking it!) Connect optical disc drive/floppy disk drive to the motherboard (don’t worry about power supply at the moment) • Label the components Group 1, 2, 3 Group 4, 5, 8 Group 6, 7

  7. Learning objectives • To understand the structure and functions of the CPU • To distinguish between RAM and ROM • To understand how memory is measured (bits, bytes, KB, MB, GB, TB, PB) • To use relative pronouns correctly

  8. Central processing unit

  9. Registers • Program counter (PC, instruction pointer or instruction address register) • a processor register that indicates where the computer is in its instruction sequence. Depending on the details of the particular computer, the PC holds either the address of the instruction being executed, or the address of the next instruction to be executed. • Instruction register (IR) • Holding the instruction currently being executed

  10. How memory is measured • ASCII • http://www.ascii-code.com/ • Uses 7-digit binary numbers (128 possible characters or symbols) to represent letters of alphabets, numbers, punctuation marks and symbols, special functions, such as the carriage return • Can ASCII be used to encode Chinese characters? • Petabyte (PB) = “two power fifty” or “two to the power of fifty”

  11.
