Question

Select statements about Multiprocessors that are FALSE. a. Asymmetric multiprocessors are a popular form of tightly coupled architecture b. Symmetric multiprocessors are a popular form of tightly coupled architecture c. Tightly coupled multiprocessors share a single centralized memory, which requires an operating system to synchronize processes carefully to ensure protection d. Loosely coupled multiprocessors have a physically distributed memory and are also known as distributed systems

Answer 1

Answer:

The statement about Multiprocessors that is FALSE is:

a. Asymmetric multiprocessors are a popular form of tightly coupled architecture

Explanation:

Symmetric multiprocessors house two or more identical processors sharing a single main memory.  The multiprocessors are tightly coupled, and all of them can access all the connected devices without any preferential treatment of one over the others.  This is unlike asymmetric multiprocessors that do not share a single main memory.   Instead, they have distributed memories.
