Computer Networking Which of the following refers to the terms "residual error rate"? The probability that one or more errors will be undetected when an error detection scheme is used signal to noise ratio divided by the ratio of energy per bit to noise per hertz None of these the number of bit errors per twenty four hours of continuous operation on an asynchronous line the probability that one or more errors will be detected when an error detection mechanism is used The probability that one or more errors will be undetected when an error detection scheme is used signal to noise ratio divided by the ratio of energy per bit to noise per hertz None of these the number of bit errors per twenty four hours of continuous operation on an asynchronous line the probability that one or more errors will be detected when an error detection mechanism is used ANSWER DOWNLOAD EXAMIANS APP
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 An additional token is added for every 1,000 nodes The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 The network becomes less efficient The network becomes more efficient 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 speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500 The network becomes less efficient The network becomes more efficient After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device ANSWER DOWNLOAD EXAMIANS APP
