How Does a PC Keep Track of Time? Insights on Real-Time Clocks and NTP

Discover how your PC knows the time using Real-Time Clocks and Network Time Protocol for synchronized accuracy.

60 views

A PC knows what time it is through a combination of hardware and network resources. Primarily, it uses a battery-powered Real-Time Clock (RTC) on the motherboard, which keeps time even when the computer is off. When the PC is powered on and connected to the internet, it can synchronize its time with online time servers using the Network Time Protocol (NTP), ensuring accurate and up-to-date timekeeping.

FAQs & Answers

  1. What is a Real-Time Clock (RTC)? A Real-Time Clock (RTC) is a battery-powered device on a computer's motherboard that keeps track of the current time even when the system is off.
  2. How does Network Time Protocol (NTP) work? Network Time Protocol (NTP) synchronizes the time on your computer with internet time servers to ensure accurate timekeeping.
  3. Why is accurate timekeeping important for a PC? Accurate timekeeping is essential for scheduling tasks, logging events, and ensuring system synchronization across networks.
  4. Can a PC still keep accurate time when offline? Yes, a PC can keep accurate time using its Real-Time Clock, but it may not be synchronized to the global time standards until it's connected to the internet.
