I. Introduction Network Time Protocol (NTP) is used to synchronize time between the distributed time server and the client. NTP is transmitted Based on UTP packets. The UDP port used is 123. NTP is used to synchronize the clock of all devices in the network, so that all devices in the network are consistent with the clock, so that the devices can provide a variety of unified applications. If a time error occurs, the server will be down. Therefore, t

specifically implemented, you cannot create objects with abstract classes.Here are a few things to note: In the 11 Select 5 Platform set up 32,663,975,971 book, the abstract class is defined as "the class containing the abstract method", but later found that if a class does not contain abstract methods, but only with the abstraction of the same abstract class. That is, abstract classes do not necessarily have to contain abstract methods. Personally think this belongs to the problem of the dead,
