serial is not a serial number, but a serial interface in the router. It is also called a serial communication interface or a serial communication interface. It is an expansion interface that uses serial communication; the serial interface refers to one bit of data. One-bit sequential transmission is characterized by simple communication lines. Only a pair of transmission lines can achieve two-way communication, thus greatly reducing costs. It is especially suitable for long-distance communication, but the transmission speed is slow.

serial is the serial number?
no. serial is the serial interface in the router. Also called serial communication interface or serial communication interface (usually referred to as COM interface), it is an expansion interface that uses serial communication.
Serial Interface (Serial Interface) refers to the sequential transmission of data bit by bit. Its characteristic is that the communication line is simple, and only a pair of transmission lines can achieve two-way communication (telephone lines can be directly used as transmission lines), thus greatly reducing costs, and is especially suitable for long-distance communication, but the transmission speed is slow.
Application introduction:
Router connection The router can be connected using the Serial port on the router or the Ethernet port.
The serial value in the DNS server is very important, and every time the domain name server is changed, the serial value must be changed to a larger value, so that the data can be successfully synchronized with the global DNS server.
Serial number, for example, if a serialization-like id is not generated for a class in the java class, a warning will be generated. In this case, you can add the following code:
@SuppressWarnings("serial ").
universal serial bus=usb universal serial interface.
