    Study Notes

    Timer and Resource Management

    • A timer is utilized to prevent infinite loops or excessive resource consumption in processes.
    • The timer interrupts a computer after a specified duration to maintain system stability.
    • A counter is maintained that decreases based on the physical clock's ticks.
    • The operating system is responsible for setting this counter, as it requires a privileged instruction.
    • When the counter reaches zero, an interrupt is generated, signaling the system to take action.
    • The timer setup occurs prior to scheduling processes to either regain control or terminate programs that exceed their allocated execution time.
