Multithreading vs Multiprocessing

Basic Definitions with Analogy:

1. Multithreading:

Definition: Multithreading is a technique where multiple threads (smaller units of a process) run concurrently within the same process, sharing the same memory and resources.

Analogy:
Imagine a restaurant kitchen where multiple chefs (threads) work together to prepare a single dish (process).

They share the same tools (resources) like knives, pots, and stoves.

Each chef has a specific task: one chops vegetables, another cooks the sauce, and another plates the dish.

The tasks depend on each other, and the chefs coordinate closely to finish the dish.

1. Multiprocessing:

Definition: Multiprocessing is a technique where multiple processes (independent programs) run concurrently, each having its own memory and resources.

Analogy:
Imagine a food court where multiple restaurants (processes) operate independently.

Each restaurant has its own kitchen (memory and resources).

One restaurant prepares burgers, another makes pizzas, and a third serves ice cream.

These restaurants work independently, and a delay or failure in one restaurant doesn’t affect the others.

Comparison:

By combining the basic definitions with this analogy, the difference between multithreading and multiprocessing becomes more intuitive.
