Computers keep accurate time using an internal clock known as the Real-Time Clock (RTC). This clock is powered by a battery even when the computer is off, ensuring continuous timekeeping. Additionally, computers often synchronize with internet time servers to correct any drift and maintain precise timing.

FAQs & Answers

  1. What is a Real-Time Clock? A Real-Time Clock (RTC) is a battery-powered clock integrated into a computer that helps maintain accurate time even when powered off.
  2. Why do computers need to synchronize with internet time servers? Computers synchronize with internet time servers to correct any potential drift in their clocks, ensuring they display accurate time.
  3. What happens if a computer's internal clock fails? If a computer's internal clock fails, it can lead to incorrect time display, affecting scheduled tasks and time-sensitive operations.
  4. How often do computers synchronize their time? Many computers synchronize their time periodically, typically every few hours or as configured by the user to maintain accuracy.
