Network Time Protocol and Atomic Clocks for Device Time Synchronization

Network Time Protocol (NTP) allows devices connected to the internet to synchronize their time with atomic clocks through a network of servers. The time is dispersed from atomic clocks to multiple servers, ensuring that devices can always retrieve the correct time. Devices without internet connection can maintain time using a small battery on the motherboard, such as the CR 2032 battery, to keep time while the computer is off.
