How Does a CPU Keep Time? Understanding the Real-Time Clock (RTC)

Discover how a CPU maintains accurate time using the Real-Time Clock (RTC) technology.

72 views

A CPU keeps time through an integrated circuit known as the Real-Time Clock (RTC). The RTC is powered by a small battery, which allows it to maintain time even when the computer is off. This clock helps ensure the computer's time and date are accurate, facilitating time-stamping and scheduling functions.

FAQs & Answers

  1. What is a Real-Time Clock (RTC)? A Real-Time Clock (RTC) is an integrated circuit that keeps track of the current time and date in a computer, even when powered off.
  2. Why is timekeeping important in a CPU? Timekeeping in a CPU is essential for ensuring accurate time-stamping, scheduling functions, and maintaining system integrity.
  3. Can the RTC function without power? Yes, the RTC can keep time even when the computer is off, thanks to a small battery that powers it.
  4. How does a computer maintain accurate time? A computer maintains accurate time through its RTC, which synchronizes time with high precision, using a dedicated power source.
