Network Port Literacy One: Network card preliminary understandingThe network adapter is also known as a NIC or network interface card (NIC), and the English name is Interface Card. It is a device that makes computers networked. What is commonly referred to as a NIC is the

control and media access control, as well as a unique hardware address, MAC address, and a cache on the NIC. The network card must be assigned interrupt IRQ and basic I/O port address, The base memory address and transceiver (transceiver) must also be set Network card control chip: The most important component of the

Port 1~1024 are reserved ports, so they are almost never the source port. But there are some exceptions, such as connections from NAT machines. See also 1.9. Often see the port immediately after 1024, which is the "dynamic port" that the system assigns to those applications that do not care which

port numbers here. One port on the RMII requires 7 data lines, one times less than Mii, so the switch can access more than one data port. Like Mii, the RMII supports the bus interface speed of 10Mbps and 100Mbps.Smii is a media interface proposed by Cisco, which has less than rmii number of signal lines, s is the meaning of serial. Because it transmits data with
