Computer Networking Ethernet and Token-Ring are the two most commonly used network architectures in the world. 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. Token-Ring, because it uses a MAU Neither Token-Ring nor Ethernet is the proper choice. Only ARCnet can be used in all topologies Token-Ring because it currently can run at both 4Mbps and 16Mbps. This means that it can be used in any topology Ethernet, because it can be set up with most topologies and can use multiple transfer speeds Ethernet, because it is cabled using fiber-optic cable Token-Ring, because it uses a MAU Neither Token-Ring nor Ethernet is the proper choice.

Computer Networking The Token-Ring architecture was developed for a more efficient way to determine who should be transmitting at any one time. With Ethernet, collisions may take place, causing the transmitting computers to have to retransmit their data. The use of token guarantees that only one computer can transmit at a time. What happens as the network increases in size? Choose the best answer After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device An additional token is added for every 1,000 nodes The network becomes less efficient The network becomes more efficient The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device An additional token is added for every 1,000 nodes The network becomes less efficient The network becomes more efficient The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 ANSWER DOWNLOAD EXAMIANS APP
