The switch can transmit data between multiple port pairs at the same time. Each port can be considered as an independent physical network segment (note: non IP network segment), and network devices connected to it alone enjoy the full bandwidth, without having to compete with other devices for use. When node A sends data to node D, node B can simultaneously send data to node C, and both transmissions enjoy the full bandwidth of the network and have their own virtual connections. If a 10Mbps Ethernet switch is used here, the total flow flux of the switch at this time is equal to 2 × 10Mbps=20Mbps, and when using a 10Mbps shared HUB, the total flow flux of one HUB will not exceed 10Mbps. In short, a switch is a network device based on MAC address recognition that can encapsulate and forward data frames. The switch can "learn" the MAC address and store it in the internal address table. By establishing a temporary exchange path between the initiator and target receiver of the data frame, the data frame can directly reach the destination address from the source address. The working principle of data transmission: After any node of the switch receives data transmission instructions, it quickly searches the address table stored in memory to confirm the connection position of the MAC address network card, and then transmits the data to that node. If the corresponding location is found in the address table, the transmission will proceed; If not, the switch will record the address for future search and use. Switches generally only need to send frames to the corresponding points, rather than sending them to all nodes like hubs, thus saving resources and time and improving data transmission rates.
