Queues are a fundamental data structure used in various real-life applications due to their First-In-First-Out (FIFO) nature. Here are some notable real-life applications of queues:
Task Scheduling:
CPU Scheduling: Queues are used to manage processes in operating systems, ensuring that tasks are executed in the order they arrive[1][3][9].
Disk Scheduling: Similar to CPU scheduling, queues help manage read/write requests to a disk[9].
Resource Management:
Printer Spooling: Print jobs are queued and processed in the order they are received, allowing multiple print requests to be managed efficiently[1][3][6].
Resource Allocation: Queues manage access to shared resources like printers or CPU time[1].
Network Protocols:
Packet Queuing: In network routers and switches, queues manage data packets to ensure they are transmitted in the correct order and at the appropriate rate[1][3][9].
Message Buffering: Queues buffer messages in communication systems, ensuring smooth data flow between sender and receiver[1].
Event Handling:
GUI Event Handling: Queues manage events in graphical user interfaces, processing user actions like clicks and key presses in the order they occur[1].
Simulation Systems: Queues handle events in simulation systems, ensuring events are processed in the correct sequence[1].
Traffic Management:
Traffic Signals: Queues manage the flow of vehicles at intersections, ensuring orderly passage through traffic lights[1][3].
Airport Control Systems: Queues manage the takeoff and landing sequences of aircraft[1].
Customer Service:
Call Centers: Incoming calls are queued and handled by the next available representative, ensuring fair and orderly service[3].
Ticketing Systems: Queues manage customers waiting for service at ticket counters, ensuring they are served in the order they arrive[3].
Data Processing:
Batch Processing: Queues handle batch jobs like data analysis or image rendering, processing tasks ...
