Tips: What is a Hub?

A hub is a device that connects multiple Ethernet twisted pairs or optical fibers together under the same physical medium. The hub is the physical layer operating in the OSI model. It can be regarded as a multi-port repeater, if it detects a collision, it will submit a blocking signal.
Since the hub will regenerate or amplify any digital signal received, and then submit it from all ports of the hub, this will cause a great chance of collision between signals, and the signal may also be eavesdropped, and this means that all connected to the hub All of the devices belong to the same collision domain name and broadcast domain name, so most hubs have been replaced by switches.
