How Do Computers Accurately Set Time Using NTP?

Discover how computers use the BIOS clock and NTP servers to set and sync time accurately.

500 views

Computers set time using a combination of the system clock and Network Time Protocol (NTP) servers. On startup, the Basic Input/Output System (BIOS) clock initializes the time. Then, an internet connection allows the computer to sync with NTP servers, ensuring accurate and up-to-date timekeeping.

FAQs & Answers

  1. What is the Network Time Protocol (NTP)? NTP is a networking protocol used for synchronizing the clocks of computer systems over packet-switched data networks.
  2. Why is accurate timekeeping important for computers? Accurate timekeeping is essential for logging events, coordinating systems, and ensuring data integrity in cloud computing and databases.
  3. How does the BIOS clock work? The BIOS clock initializes the computer's time upon startup, providing a baseline that the system clock continues to update.
  4. Can computers set time without an internet connection? Yes, computers can maintain time using the BIOS clock even without an internet connection, but they won't be able to sync with NTP servers for accuracy.
