What is the name of the protocol that maps Ethernet addresses to IP addresses? 1.3. Assuming odd parity is used, and the frame to be transmitted is 1001010, what is the parity bit to be appended to the frame? 1.4. By sensing the channel prior to sending, are we sure that a station would never DID collide with another one in all circumstances? 1.5. Describe a scenario that the use of a single parity bit fails to detect transmission errors to a frame, say 1001010. 1.6. By looking at the destination MAC address, how do you know if an Ethernet frame is a multicast frame? 1.7.
