Bit oriented and character oriented protocols

What is the differences in between bit oriented and character oriented protocols

Character – Oriented Protocols

• Also called Byte- Oriented Protocol
• These protocols interpret a transmission frame or packet as a succession of characters, each usually composed of one byte
• All control information is in the form of an existing character encoding system

Bit – Oriented Protocols

• Character –Oriented Protocols are not as efficient as bit – oriented protocols and are seldom used
• They are easy to comprehend and employ the same logic as bit-oriented protocols
• Their study will provide the basis for studying the other data link layer protocols
• IBN’s BSC is the best known character oriented protocol
