Network Time Protocol (NTP) is a standard Internet protocol used for time synchronization on the Internet. NTP is used to synchronize computer time to certain time standards. The current time standard is Universal Time coordinated ). The primary developer of NTP is Professor David L. Mills from the University of Delaware. What is the use of
communication process is as follows: 1. First, the host needs to start the NTP service. 2. The client sends a message to the NTP server to adjust the time. 3. The NTP server then sends the current standard time to the client 4. After the client receives the time from the
