D 12. Your network consists of a 24-port bridge‚ two servers‚ and 15 workstations. Each computer interfaces with the bridge using its own segment of CAT 5 twisted-pair cable‚ which is terminated at both ends with RJ-45 connectors. What type of physical topology do you have? a. Mesh b. Bus c. Ring d. Star Answer: This is an example of the “Star” topology‚ although the only cabling type that has to be terminated

Cat 6 cable supports up to 10 Gigabit Ethernet for up to about 37 meters or 121 feet. Cat6 cables are made up of four twisted sets of copper wire and its abilities surpass cat5 and cat5e types of data cabling because it has a structural difference in its longitudinal separator 3.
