Concurrency

Concurrency is a computer system’s ability to run multiple tasks or processes simultaneously to improve efficiency. It splits programs into smaller, independent functions that can run in parallel, better using resources and speeding up execution. This is especially useful on multi-core processors. Concurrency is key in computer science and software engineering, helping to create responsive and scalable applications. Web servers must manage many user requests or real-time systems where tasks must work together without conflict. Managing concurrency needs careful planning to avoid issues like data corruption or deadlocks, where tasks block each other. While concurrency improves performance and responsiveness, it also adds challenges in design and testing, requiring extra effort to ensure systems behave as expected.
