Queueing is the process of organizing items or people in a line to wait for service or access to a resource. This system helps manage demand and ensures that everyone is served in an orderly manner. Common examples of queueing can be seen in places like banks, restaurants, and theme parks, where individuals wait their turn for assistance or entry. In computer science, queueing refers to managing data packets or tasks that need processing. This is crucial in systems like networking and operating systems, where multiple requests may arrive simultaneously. Efficient queueing helps optimize performance and reduce wait times for users.
