The definition A relatively small amount (when compared to primary memory) of very high speed
RAM, which holds the instructions and data from primary memory, that has a high probability of
being accessed during the currently executing portion of a program refers to what category of
computer memory?
A.
Secondary
B.
Virtual
C.
Real
D.
Cache
Explanation:
Cache logic attempts to predict which instructions and data in main (primary) memory will be used
by a currently executing program. It then moves these items to the higher speed cache in
anticipation of the CPU requiring these programs and data. Properly designed caches can
significantly reduce the apparent main memory access time and thus increase the speed of program
execution. * Answer secondary memory is a slower memory (such as a magnetic disk) that provides
non-volatile storage. * Real or primary memory is directly addressable by the CPU and is used for the
storage of instructions and data associated with the program that is being executed. This memory is
usually high-speed, Random Access Memory (RAM). * Answer virtual memory uses secondary
memory in conjunction with primary memory to present the CPU with a larger, apparent address
space of the real memory locations.
