How Do Devices Accurately Keep Track of Time?

Discover how devices track time precisely using Real-Time Clocks and internet synchronization.

88 views

Devices keep track of time using an internal Real-Time Clock (RTC) that runs on a small, dedicated battery. This clock maintains time even when the device is powered off. Additionally, devices sync with internet time servers (NTP) to ensure accuracy.

FAQs & Answers

  1. What is a Real-Time Clock? A Real-Time Clock (RTC) is a battery-operated clock present in devices that keeps track of the current time even when the device is turned off.
  2. How does NTP synchronize time? NTP, or Network Time Protocol, syncs a device's clock with accurate time sources over the internet, ensuring precise timekeeping.
  3. Why is timekeeping important in devices? Accurate timekeeping is crucial for scheduling tasks, logging data, and maintaining the functionality of various applications within devices.
  4. Can devices lose track of time? Yes, if a device's battery dies or it loses internet connection, it can lose accuracy until it syncs again with a time server.
