Understanding Computer Clock Accuracy: How Close Are They?
Discover how precise computer clocks are and the role of network time protocols in time synchronization.
0 views
Computer clocks are generally accurate to within a few seconds per day. However, network time protocols (NTP) can be used to synchronize them with a precise time server, maintaining an accuracy of milliseconds. Regular synchronization helps in activities that require precise timekeeping, like financial trading or server logging.
FAQs & Answers
- How does network time protocol (NTP) work? NTP synchronizes the clocks of computer systems over packet-switched data networks to keep them accurate.
- Why is accurate timekeeping important in financial trading? Precise timekeeping ensures synchronized transactions, which is essential for fair trading practices.
- What factors can affect computer clock accuracy? Variability in temperature, power supply fluctuations, and lack of synchronization can all impact clock accuracy.
- What devices utilize NTP for clock synchronization? Many devices, including servers, routers, and even personal computers, use NTP to ensure accurate timekeeping.
