Multitasking, multithreading, and multiprocessing are all terms that describe the ability of a computer to run multiple tasks at the same time. However, they have different meanings and implications.
Multitasking is the ability of an operating system to run multiple programs at the same time. This is done by switching between the programs very quickly, so that it appears that they are all running at the same time. Multitasking can be done on a single-processor computer, but it is more efficient on a multi-processor computer.
Multithreading is a technique for running multiple tasks within the same program. This is done by dividing the program into multiple threads, each of which can run independently. Threads can share the same resources, such as memory and CPU time, but they can also run in parallel. Multithreading can improve the performance of a program by allowing it to do multiple things at the same time.
Multiprocessing is the use of multiple processors in a computer system. This allows the computer to run multiple tasks at the same time, and it can also improve the performance of a program. Multiprocessing can be done by using multiple CPUs in a single computer, or by using multiple computers that are connected together.
Here is a table summarizing the differences between multitasking, multithreading, and multiprocessing:
