Brief about how line coding implemented in fddi and describe its format

Answer 1

Line coding implemented in FDDI and its format is:

• The FDDI is Fiber Distributed Data Interface is an American National Standards Institute standard for a 100-mbps network.
• The Physical sublayer specifies that the stations must use the 4B/5B encoding.
• With this encoding, the transmitter groups the bits by 4 and converts each 4-bit word into 5-bit word specified by the encoding table.
• The FDDI format is similar to the format of a Token Ring frame
