concurrency models

Concurrency models describe how a computer handles multiple tasks simultaneously. Think of it like a busy restaurant: some models let tasks take turns quickly (like switching between orders), while others assign dedicated staff to specific tasks. For example, multi-threading divides work into parts that can run at the same time, improving efficiency, while event-driven models respond to events (like customer orders) as they arrive. These models help computers manage many operations smoothly, maximizing performance and responsiveness, especially in complex or high-demand situations.
