How Do Computers Keep Accurate Time Without the Internet?

Discover how computers maintain accurate time using an internal clock, even when offline.

45 views

Computers keep track of time without the internet by using an internal hardware component called the Real-Time Clock (RTC). The RTC is powered by a small battery even when the computer is turned off, ensuring that the time remains accurate. When a computer turns on, it reads the date and time from the RTC, allowing it to operate correctly without needing an internet connection.

FAQs & Answers

  1. What is a Real-Time Clock (RTC)? A Real-Time Clock (RTC) is a hardware component that keeps track of the current time and date, even when the computer is off, using a small battery.
  2. Can computers still keep accurate time without being connected to the internet? Yes, computers can keep accurate time using their internal Real-Time Clock, which operates independently of internet connectivity.
  3. How long does the RTC battery last? The RTC battery can last several years, depending on the type of battery used and how frequently the device is powered down.
  4. What happens to the time when a computer is turned off? When a computer is turned off, the RTC continues to keep time powered by its battery, ensuring that the time remains accurate until the computer is turned back on.
