Understanding Concurrency Models

This animation illustrates how concurrent programs execute multiple tasks that appear to run simultaneously, using interleaved timelines of threads or processes sharing a CPU. It visualizes key ideas like context switching, shared memory access, and race conditions when two threads modify the same variable without synchronization. The animation helps students see why ordering matters and why locks or atomic operations are needed, making it useful for anyone learning operating systems, parallel programming, or software engineering fundamentals.
