How Do Computers Keep Accurate Time Without Internet?

Discover how computers maintain time accuracy using Real-Time Clocks without needing an internet connection.

6 views

Computers keep time without the internet using an internal clock known as a Real-Time Clock (RTC). This hardware component runs on a small battery, allowing it to maintain accurate time even when the computer is powered off. When you reboot your computer, the RTC provides the correct time to the operating system.

FAQs & Answers

  1. What is a Real-Time Clock (RTC)? A Real-Time Clock (RTC) is a hardware component in computers that keeps track of the current time, even when the system is powered off.
  2. Do all computers have an internal clock? Yes, all computers come equipped with an internal clock that is crucial for maintaining system timing and scheduling tasks.
  3. How does a computer's RTC work? The RTC operates on a small battery, allowing it to function independently of the main power supply and keep accurate time.
