For many computational purposes, serial processing is sufficient; it's easy to implement and fast enough for most users.

• TRUE

• FALSE

For multiprocessing systems, the Processor Manager has to coordinate the activity of each processor, as well as synchronize the interaction among the CPUs.

• TRUE

• FALSE

Implied parallelism includes automatic detection by the compiler of instructions that can be performed in parallel.

• TRUE

• FALSE

In a loosely coupled system, a job may move from one processor to another during execution.

• TRUE

In a master/slave system, the master processor is responsible for managing the entire system-all files, devices, memory, and processors.

• TRUE

• FALSE

In a symmetric configuration, processor scheduling is centralized.

• TRUE

• FALSE

In parallel computations mutual exclusion is achieved automatically because each operation is handled in order, one at a time.

• TRUE

• FALSE

Multiplying two 3x3 matrices requires 45 operations when performed in parallel using three processors.
