Jim has heard of the different topologies for networks and wants to choose the architecture that will provide him with the most options. Which of the following would that be? Choose the most correct answer.
a. Token-Ring, because it uses a MAU
b. Ethernet, because it can be set up with most topologies and can use multiple transfer speeds
c. Neither Token-Ring nor Ethernet is the proper choice. Only ARCnet can be used in all topologies
d. Token-Ring because it currently can run at both 4Mbps and 16Mbps. This means that it can be used in any topology
Answer: (b). Ethernet, because it can be set up with most topologies and can use multiple transfer speeds
