Q: 1 The number threads in thread pool depends on

  1. No. of processes

  2. No. of threads

  3. No. of processes and threads communicate each other

  4. No. of the exited threads

[ Option B ]

A thread pool is a collection of pre-created threads used to execute tasks efficiently. The size of the thread pool depends on the number of threads allocated for execution, which is usually decided based on system requirements like CPU cores and workload.

Q: 2 In a multithreaded process, which of the following is not shared among threads?

  1. Registers

  2. Data

  3. Code

  4. Files

[ Option A ]

In a Multithreaded Process, multiple threads run within the same process and share certain resources to efficiently perform tasks concurrently. Threads belonging to the same process share the code section, data section, and files.
However, each thread requires its own Registers and Stack to keep track of its current state, local variables, and execution context.

Q: 3 Consider the following statements:
A: Multithreaded applications are characterized by having a small number of highly threaded processes.
B: Multiprocess applications are characterized by the presence of many single-threaded processes.
Which of the following is true about the above statements?

  1. Only A is correct.

  2. Only B is correct.

  3. Neither A nor B is correct.

  4. Both A and B are correct.

[ Option D ]

Multithreading refers to a programming model where multiple threads run within the same process, sharing the same memory space but executing different tasks concurrently.
Multiprocessing, on the other hand, uses multiple processes, each with its own separate memory and resources.
