  1. When is RAM used?
    When you access a program or data it is copied from mass storage to RAM
  2. How many bits can a semiconductor hold?
    One bit either a 1 or a 0
  3. How are the 1s and 0s stored?
    with microscopic transistors and capacitators
  4. Where do DRAM makers put these semiconductors?
    Onto chips that can hold a certain number of bits
  5. How are the bits inside the chips organized?
    in a rectangular fashion using rows and columns
  6. True or false..each chip has a limit on how many lines of code it can handle.
  7. How many bits were in the original 8088 processor have in the front side bus?
    8 bits
  8. How was 1-bit-wide DRAM turned into 8-bit-wide memory?
    Put eight 1-bit-wide chips in a row on the motherboard, and then wire up this row of DRAM chips to the memory controller chip (which has to be designed to handle this) to make byte-wide memory.
  9. How did the 8088 handle 2 byte commands?
    It took it 1 byte at a time. The MCC had to go back 2wice.
  10. What was the 8086?
    Intel's 16 bit cpu
  11. What are the reasons Intel didn't sell IBM the 8086 instead of the 8088
    Nobody had invented an affordable MCC or RAM that handled two bytes at a time
  12. What does SIMM stand for?
    Single inline memory module
  13. What form factors do modern memory sticks come in?
    32 bit and 64 bit form factors
  14. Who keeps track of the memory addresses the cpu or the mcc?
Card Set
