Concurrency & Parallelism

Ever notice how your computer can play music, download files, and browse the web all at the same time? This isn't magic; it's the power of multi-tasking!

In system design, we often need our applications to handle many operations efficiently. This is where the concepts of concurrency and parallelism become crucial.

Concurrency is about dealing with many things at once. Think of a chef juggling multiple cooking tasks in a single kitchen.

• The chef might chop vegetables, then stir a pot, then check an oven.
• They're not doing everything simultaneously, but they're making progress on several tasks by switching between them quickly.
• This gives the illusion of simultaneous execution.
