Detailed explanation-1: -How many bytes of padding must be added to the data? The minimum length of an Ethernet frame is 64 bytes. Therefore the minimum length of data from the upper layer is (64 bytes – 18 bytes) 46 bytes. You must add (46 bytes – 42 bytes) 4 bytes of padding to the data.
Detailed explanation-2: -The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It is responsible for flow control and multiplexing for transmission medium. It controls the transmission of data packets via remotely shared channels.
Detailed explanation-3: -The MAC layer interacts with the physical layer and is responsible for the. During the encapsulation process, generation of the frame start synchronization signals, coding of the source/destination address, and physical media transmission error detection are implemented.
