In the OSI networking stack, the Layer is responsible for framing, error detection, media access: Ethernet, Wifi/802.11, FDDI, ATM Network Layer Physical Layer Transport Data link layer In the OSI networking stack, the Layer is responsible for: encoding of bits and transmission Physical Layer Network Layer Transport Layer In the OSI networking stack, the Layer is responsible for: reliability, endpoint addressing, flow control, congestion control, ordering: TCP, UDP Transport Layer Network Layer Presentation Layer Suppose we want to transmit a message and protect it from errors using the CRC polynomial x4+1. Use polynomial long division to determine if this message 1100100011101 was transmitted correctly to the receiver or there was an error in transmitting. No Errors in message Delivered with Error
