Description: The ‘Arrival Time’ refers to the moment when a process enters the ready queue for execution in a computing system. This concept is fundamental in CPU scheduling, as it determines when a process is available to be executed by the processor. Arrival time is a key indicator that influences system efficiency, as it affects how processes are managed and scheduled. In a multitasking environment, where multiple processes compete for CPU time, arrival time helps schedulers decide the order in which processes should be attended to. A process with an earlier arrival time may be prioritized over others that arrive later, which can improve system responsiveness and user experience. Additionally, arrival time is used in calculating performance metrics, such as waiting time and response time, which are crucial for evaluating the effectiveness of a scheduling algorithm. In summary, arrival time is an essential aspect of process management, as it establishes the starting point for execution and directly affects the overall efficiency of the computing system.
