I've a question regarding the system clock and I wrote a paragraph about it but I'm not sure if I've got it all right. Take a look
"The micoprocessors have a range of tasks and one implementation of such a task is system time. Every computer has a built-in hardware clock, a real-time clock, and a virtual clock, also called system clock. The real-time clock is always counting and it is only when the computer is on that the real-time clock is converted to the system clock. This happens in the BIOS during initialization and after this synchronization the clocks move independent of each other. The system clock is implemented as a programmable interval timer that interrupts the CPU. The CPU then starts a timer interrupt service routine in which a 'tick' on the clock is added. At this point, the computer can display the correct time."
Is this a correct assertion?
