How Accurate Are Computer Clocks? Insights into Time Synchronization

Discover how accurate computer clocks are and the technology behind their synchronization.

276 views

Computer clocks are typically accurate to within a few seconds per day. They rely on quartz crystal oscillators, which can drift due to temperature changes. To maintain accuracy, computers often synchronize with network time servers using protocols like NTP (Network Time Protocol). Regular synchronization ensures the clock remains accurate and reliable.

FAQs & Answers

  1. What is the main technology behind computer clocks? Computer clocks primarily use quartz crystal oscillators for maintaining time accuracy.
  2. How does network time synchronization work? Network time synchronization uses protocols like NTP to align computer clocks with precise time servers.
  3. Why do computer clocks drift? Computer clocks can drift due to factors like temperature changes that affect the quartz oscillators.
  4. How often should computers synchronize their clocks? Regular synchronization is recommended to maintain accurate time, typically performed at intervals set by system preferences.
