Understanding How Computers Measure Time with System Clocks
Learn how computers use system clocks and real-time clocks to measure time efficiently.

Computers measure time using an internal component called the system clock, which is a hardware clock built into the motherboard. This clock sends out regular electrical pulses, usually in the range of millions per second (megahertz), which the computer uses to synchronize all its operations. For more precise timing, computers utilize a real-time clock (RTC) that keeps track of actual time even when the computer is off. This combination allows computers to perform tasks in time-sensitive intervals.
FAQs & Answers
- What is a system clock in a computer? A system clock is a hardware clock within the motherboard that regulates the timing of all computer operations.
- What is the purpose of a real-time clock? A real-time clock (RTC) keeps track of the current time and date even when the computer is powered off.
- How does a computer synchronize its operations? Computers synchronize operations using electrical pulses generated by the system clock to maintain timing across processes.
- Why are timing intervals important in computing? Timing intervals are crucial for ensuring tasks are performed accurately and efficiently in synchronous operations.
