True/False: The CPU clock cycle length is the only contributing factor
to the speed of operations on a computer. - answer False.

, It is one of the contributing factors, but not the only one. The other
factors include the ISA, cache memory, memory speed, and
input/output speed


True/False: A primary limitation on the speed of internal
communication on a machine is the width of the internal bus. -
answer True.


For example, if a bus has the width of 32 bits, then it can transfer
32 bits of data at the same time. The wider the width, the faster
data transfer.


Place the steps for a memory read in the correct order - answer
Specify the memory address on the address bus via MAR


assert a read


wait until operation is complete


move data to its destination


What would you call an ordered list of organized instructions
existing somewhere in memory, and associated with a data
structure for storage of data? - answer Program


Step 1 of the instruction Execution - answer Fetch the instruction
at the address in the instruction pointer into the instruction register


Step 2 of the instruction Execution - answer Increment the
instruction pointer to point to next instruction's address
