Understanding How Computers Perceive Time: The System Clock Explained

Discover how computers track time using an internal system clock and NTP servers for precision.

172 views

Computers perceive time through an internal clock known as the system clock. This clock generates regular electrical pulses, which the computer uses to keep track of time, calculate durations, and synchronize processes. The system clock is periodically updated via the internet by Network Time Protocol (NTP) servers to ensure precision and accuracy.

FAQs & Answers

  1. What is the system clock in a computer? The system clock is an internal mechanism that generates electrical pulses to track time and synchronize processes within the computer.
  2. How does Network Time Protocol (NTP) work? Network Time Protocol syncs the system clock with online servers to ensure accurate timekeeping across devices.
  3. Why is accurate time synchronization important in computing? Accurate time synchronization is essential for managing processes, record-keeping, and maintaining the integrity of data in distributed systems.
