What is PRAM Full Form in Computer?
The PRAM full form in computer is Parallel Random Access Machine. PRAM is a model used for the majority of parallel algorithms. It facilitates the development of a precursor parallel algorithm free of architectural constraints, as well as allowing parallel-algorithm designers to assume processing capacity as limitless. It ignores the complexities of interprocess communication. PRAM algorithms are primarily theoretical, although they can serve as the foundation for designing an efficient parallel algorithm for practical devices, as well as motivating the development of specialized machines.
Architectural model of PRAM:
PRAM consists of a control unit, global memory, and an infinite number of comparable processors, each with its own private memory. It has an active processor reads from global memory, does the necessary computations, and then writes to global memory. As a result, if a PRAM has N processors, it can do N independent operations in a given amount of time.
Significance of PRAM model:
The PRAM paradigm simplifies parallel computing by assuming that all processors may access memory in the same time, regardless of the number of processors or memory architecture. This paradigm is useful for analyzing algorithms because it gives a framework for investigating how they perform when executed in a parallel environment, assisting researchers and developers in understanding the possible speedups that can be realized through parallelism.
