How Does My Computer Keep Accurate Time? Understanding Internal Clocks

Discover how your computer maintains accurate time using internal clocks and internet synchronization.

0 views

Your computer knows the time through its internal clock. This clock is synchronized with internet time servers via the Network Time Protocol (NTP). When your computer connects to the internet, it automatically updates the time to ensure accuracy. Even without internet, your computer maintains time with a built-in battery-powered clock, known as the Real-Time Clock (RTC), which keeps track of time while the device is off.

FAQs & Answers

  1. What is the Network Time Protocol? The Network Time Protocol (NTP) is a networking protocol used to synchronize the clocks of computers over a network.
  2. How does a computer keep time without the internet? A computer uses a battery-powered Real-Time Clock (RTC) to maintain time even when it is turned off or disconnected from the internet.
  3. Why is accurate computer time important? Accurate time is crucial for syncing data, coordinating tasks, maintaining security protocols, and ensuring timestamps are correct.
