Explain the concept of multithreading and how it differs from multiprocessing.
Answer:
- Multithreading: Multithreading is a programming technique where multiple threads within a process execute concurrently, sharing the same memory space and resources. Threads enable concurrent execution of tasks and can improve performance by leveraging multiple CPU cores. However, multithreading introduces complexities such as race conditions, synchronization, and thread safety.
- Multiprocessing: Multiprocessing involves running multiple processes simultaneously, each with its own memory space and resources. Processes are isolated from each other and communicate through inter-process communication mechanisms like pipes, queues, or shared memory. Multiprocessing provides better isolation and fault tolerance than multithreading but may incur higher overhead due to process creation and communication.
