Summary
In the field of computer science, a process is an instance of a specific computer program or software that is being executed by the operating system. A process contains both the program code and its current activities and interactions with other entities. More than one thread can be implemented within the same process to access and share memory or other resources, while different processes do not interact in this way.
In the context of concurrency and parallelism, multiprocessing refers to the execution of multiple concurrent processes from an operating system, in which each process is executed on a separate CPU, as opposed to a single process being executed at any given time. The multiprocessing module in Python provides a powerful and flexible API to spawn and manage processes for a multiprocessing application. It also allows complex techniques for interprocess communication via the Queue class.
In the next chapter, we will be discussing a more advanced function of Python—reduction...
