The computer clock works by using a quartz crystal oscillator that vibrates at a consistent frequency when an electric current passes through it. This creates precise time intervals used to keep track of time. The real-time clock (RTC) chip maintains the time even when the computer is off, powered by a small battery. The operating system then syncs its software clock with the RTC to manage scheduling and time-stamping tasks.

FAQs & Answers

  1. What is a computer clock? A computer clock is a device that maintains the timing and synchronization of a computer's operating system and processes.
  2. How does a quartz crystal affect the computer clock? The quartz crystal oscillates at a consistent frequency, which provides precise time intervals essential for accurate timekeeping.
  3. What happens to the computer clock when the computer is off? The real-time clock (RTC) chip continues to keep time even when the computer is turned off, using a small battery for power.
  4. Why is timekeeping important in computers? Accurate timekeeping is crucial for scheduling tasks, time-stamping events, and maintaining coordination among processes.
