Assignment Help:

PRAM is one among the models which are used for designing the parallel algorithm as shown in Figure. The PRAM model comprises the following components:

i)  A group of identical type of processors say P1, P2, P3 ...Pn.

ii)  It comprises a single shared memory module being shared by all the N processors. Because the processors can't communicate with each other directly, shared memory behaves like a communication medium for processors. 

iii)  In order to attach the N processor with single shared memory a component known as Memory Access Unit (MAU) is used for accessing shared memory.
