Do the cascades of hubs (not switches) need the same hub speed?
First of all, you should know that hub is just a multi-port repeater with no cascade. He just shapes and amplifies the signal. However, it has the maximum allowable speed limit, so if you connect a 10M hub with a 10M hub, the maximum speed of a computer connected with a 10M hub can only be10m. If the 10M hub is connected first and then the 100M hub is connected, the maximum speed is 65438.
