Parallelism
Domain: Computer Systems
🎯 Motivation
Doing multiple things simultaneously. Requires multiple CPU cores. True simultaneous execution.
📋 Concrete Example
4 CPU cores, 4 threads: each thread runs on a separate core simultaneously. 4 calculations done at the same time. True parallelism. 4x faster than 1 core.
🔗 Analogy
Parallelism is like 4 chefs cooking 4 dishes simultaneously in 4 kitchens. True simultaneous work. Concurrency is 1 chef switching between 4 dishes.
