While reading a book, I came across a paragraph given below:
In order to synchronize all of a computer’s operations, a system clock—a small quartz crystal located on the motherboard—is used. The system clock sends out a signal on a regular basis to all other computer components.
And another paragraph:
Many personal computers today have system clocks that run at 200 MHz, and all devices (such as CPUs) that are synchronized with these system clocks run at either the system clock speed or at a multiple of or a fraction of the system clock speed.
Can anyone kindly tell:
- What is the function of the system clock? And what is meant by “synchronize” in the first paragraph?
- Is there any difference between “system clock” and “CPU clock”? If yes, then what is the function of the CPU clock?
