concurrency

Concurrency refers to the ability of a system to handle multiple tasks or processes simultaneously, enabling them to make progress independently. In everyday life, think of a restaurant where a waiter serves multiple tables at once, taking orders, delivering food, and clearing plates all at the same time. Each task can be in progress without waiting for the others to finish. In computing, concurrency allows programs to efficiently use resources by performing different operations at the same time, improving overall performance and responsiveness, much like how a busy restaurant operates smoothly despite managing several customers.
