Synchronization of bits d. Connection controlHow do repeaters and bridges operate in the OSI model, and what problems do they address?
- A bus topology is known for being Simple and dependable Robust Efficient and effective ReliableExplain why collision is an issue in a random-access protocol but not in reservation or channel partitioning protocols.In a datagram network, two columns are required; in a virtual-circuit network, four columns are required. Is there an explanation for this? Is there a difference in the type of addresses that each network uses?
- Explain how bridges operate at the data link layer of the OSI model.Computer Science A Go-Back-N (GBN) ARQ scheme has been designed with window-size W = 10 such that it is fully efficient when there are no errors on the channel. Assume that frame size is 20000 bits and the overhead bits are negligible. What is the bit probability error (as seen at Layer 2) that makes the Go-Back-N ARQ 50% efficient?1) A bus topology is known for being a) Simple and dependable b) Robust c) Efficient and effective d) Reliable
