- Operating system functions may include
- Which layer of international standard organization's OSI model is responsible for creating and recognizing frame boundaries?
- Which of the following might be used by a company to satisfy its growing communications needs?

- 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
