Python Concurrency and Parallelism - Important Points


26. Which of the following is an example of a parallel algorithm?

A. Merge sort

B. Bubble sort

C. Quick sort

D. Insertion sort

Discuss Work Space

Answer: option a

Explanation:

Merge sort is an example of a parallel algorithm, as it can be executed using multiple processors or threads to speed up the sorting process.

27. Which of the following is a disadvantage of using multiprocessing in Python?

A. It can be more difficult to share state between processes.

B. It can be less efficient than using threads.

C. It can be more difficult to synchronize tasks between processes.

D. It can be more difficult to detect and debug issues in multiprocessing code.

Answer: option a

Explanation:

One disadvantage of using multiprocessing in Python is that it can be more difficult to share state between processes than between threads, which can make it harder to manage and debug multiprocessing code.

28. Which of the following is an advantage of using threads instead of processes in Python?

A. They can share state more easily.

B. They can be more efficient than using processes.

C. They can be easier to synchronize.

D. They can be easier to debug.

Answer: option a

Explanation:

One advantage of using threads instead of processes in Python is that they can share state more easily, which can make it easier to manage and debug code that requires shared state.

29. Which of the following is a method of creating a new thread in Python?

A. Using the multiprocessing module

B. Using the threading module

C. Using the concurrent.futures module

D. Using the asyncio module

Discuss Work Space

Answer: option b

Explanation:

The threading module provides a method of creating a new thread in Python using the Thread class.

30. What is the purpose of the concurrent.futures module in Python?

A. To provide a simple way to create and manage threads and processes.

B. To provide a way to execute code concurrently using coroutines.

C. To provide a way to execute code concurrently using threads and processes.

D. To provide a way to manage and control concurrency in Python code.

Discuss Work Space

Answer: option c

Explanation:

The concurrent.futures module in Python provides a way to execute code concurrently using threads and processes, making it easier to write concurrent and parallel code.
