When two computers communicate with each other, they send information back and forth. If they are separated by a reasonable distance, they can send and receive the information through a direct cable connection which is called a null-modem connection. Presently what is the maximum distance in metres permitted in this null-modem connection?
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
Options: 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, After the number of nodes exceeds 550, the Multistation Access Unit must be replaced by the more powerful Hyperstation Unified Bandwidth device
