Explanation / Answer

18.

items near those accessed recently and likely to be accessed soon is spatial locality.

items accessed recently and likely to be accessed again soon is temporal locality.

spatial locality relating to memory is memory locality.

The answer is D spatial locality

19.

The answer is D. 250+100+50+50

time taken to compute = 250

time taken by address = 100

time taken for reading the register = 50

time taken for writing or storing data to registers = 50

therefore total time = clock cylce time = 250+100+50+50

20

Answer is D

the first step st0 = 4

second step st1=7

third step st0=11

fourth step st1=4

fifth step st0=7
