Question

Which of the following is a feature of a multiprocessor?
1. The processors can share the memorey.
2. It has multiple computers, each of which can have multiple processors.
3. It supports distributed computing.
4. It is called message passing multi computers.

Answer 1

Correct Answer - Option 1 : The processors can share the memorey.

Explanation:

• A multiprocessor is a computer system with two or more central processing units (CPUs) sharing the same RAM. Hence option (1) is the correct answer.
• The major purpose of adopting a multiprocessor is to speed up the system's execution, with fault tolerance and application matching coming in second.
• Multiprocessors are divided into two types: shared memory multiprocessors and distributed memory multiprocessors.
• A shared memory multiprocessor's CPUs share the common memory, but a distributed memory multiprocessor's CPUs each have their own private memory.

• A computer system with a single central processing unit that executes computer operations is known as a uniprocessor system.
• Multithreading is a program execution mechanism that allows several threads to be formed within a process, each of which can execute independently while sharing process resources.
