When is RAM used?
When you access a program or data it is copied from mass storage to RAM
How many bits can a semiconductor hold?
One bit either a 1 or a 0
How are the 1s and 0s stored?
with microscopic transistors and capacitators
Where do DRAM makers put these semiconductors?
Onto chips that can hold a certain number of bits
How are the bits inside the chips organized?
in a rectangular fashion using rows and columns
True or false..each chip has a limit on how many lines of code it can handle.
How many bits were in the original 8088 processor have in the front side bus?
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.
How did the 8088 handle 2 byte commands?
It took it 1 byte at a time. The MCC had to go back 2wice.
What was the 8086?
Intel's 16 bit cpu
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
What does SIMM stand for?
Single inline memory module
What form factors do modern memory sticks come in?
32 bit and 64 bit form factors
Who keeps track of the memory addresses the cpu or the mcc?
Chapter 1 and 2
