  • Page 8 All manuals and user guides at all-guides.com 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 corrupt or redundant data.
