Inside the early times of Quick Ethernet, Ethernet switches ended up fairly high priced gadgets. Hubs endured from the problem that if there were any 10BASE-T equipment connected then The full network necessary to operate at 10 Mbit/s. For 카지노 that reason, a compromise concerning a hub as well as a swap was developed, generally known as a twin-speed hub. These units make full use of an inner two-port change, bridging The ten Mbit/s and 100 Mbit/s segments.
