NTP

Real time clock

Linux uses the RTC only during boot to derive the time and date
Keeps track of time even when the PC is switched off (RTC is powered by battery in the motherboard)
Periodic interrupts at 2Hz ~ 8192Hz, or programmed to interrupt when RTC reaches a specific value (like alarm clock)
