Program vs Process vs Thread
Explore the distinctions between programs processes and threads to understand how they operate and interact in Python concurrency. Learn the importance of managing shared states among threads to prevent common synchronization bugs in multithreaded environments.
We'll cover the following...

A program is a set of instructions and associated data that resides on the disk and is loaded by the operating system to perform a task. An executable file or a python script file are examples of programs. In order to run a program, the operating system's kernel is first asked to create a new process, which is an environment in which a program is executed.
