Multithreading is a threading technique in Python programming to run multiple threads concurrently by rapidly switching between threads with a CPU help (called context switching). Besides, it allows sharing of its data space with the main threads inside a process that share information and communication with other threads easier than individual processes. Multithreading aims to perform multiple tasks simultaneously, which increases performance, speed and improves the rendering of the application
When to use Multithreading in Python?
It is a very useful technique for time-saving and improving the performance of an application. Multithreading allows the programmer to divide application tasks into sub-tasks and simultaneously run them in a program. It allows threads to communicate and share resources such as files, data, and memory to the same processor. Furthermore, it increases the user's responsiveness to continue running a program even if a part of the application is the length or blocked.
Multiprocessing refers to the ability of a system to support more than one processor at the same time. Applications in a multiprocessing system are broken to smaller routines that run independently. The operating system allocates these threads to the processors improving performance of the system.
When to use Multiprocessing in Python?
Multiprocessing is essential to perform the multiple tasks within the Computer system. Suppose a computer without multiprocessing or single processor. We assign various processes to that system at the same time.
It will then have to interrupt the previous task and move to another to keep all processes going. It is as simple as a chef is working alone in the kitchen. He has to do several tasks to cook food such as cutting, cleaning, cooking, kneading dough, baking, etc.
Therefore, multiprocessing is essential to perform several task at the same time without interruption. It also makes easy to track all the tasks. That is why the concept of multiprocessing is to arise.
Multiprocessing can be represented as a computer with more than one central processor.
A Multi-core processor refers to single computing component with two or more independent units.
