Specify either "Write Through" or "Write Back" as the policy which best corresponds to each of the conditions below.

1) Main memory is kept coherent (consistent with cache contents) at all times.
2) Utilizes dirty bits.
3) All sw $t1,0($s0)(i. e. store word) instructions become slowed down to execute at the access time of main memory.
4) References for those sw $t1,0($s0)instructions which are hits will operate at the access time of cache.

Me with this program in c++ ! computers represent color by combining sub-colors red, green, and blue (rgb). each sub-color's value can range from 0 to 255. thus (255, 0, 0) is bright red. (130, 0, 130) is a medium purple. (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (in other word, equal amounts of red, green, blue yield gray).given values for red, green, and blue, remove the gray part. ex: if the input is 130 50 130, the output is: 80 0 80. thus, find the smallest value, and then subtract it from all three values, thus removing the gray.
