network, eliminated congestion problems inherent with CSMA/CD (Carrier Sense
multiple access with Collision Detection) protocol, and greatly reduced
unnecessary transmissions.
This revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port (Full-duplex), which essentially doubled the
bandwidth. Second, by reducing the collision domain to a single switch-port,
which eliminated the need for carrier sensing. Third, by using the
store-and-forward technology’s approach of inspecting each packet to intercept
