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 more efficient
The network becomes less efficient
The speed of the Token-Ring network must be 16Mbps if the number of nodes is greater then 500
