A protocol that begins and ends with the same bit sequence (01111110) referred to as a flag. SDLC is a bit-oriented protocol.
A communications protocol that uses only one special character, called the flag character, to mark the beginning and end of a message. All other combinations of bits are treated as valid data characters.
A protocol which does not recognize character boundaries during transmission.
Class of data link layer communication protocols that can transmit frames regardless of frame content. Compared with byte-oriented protocols, bit-oriented protocols provide full-duplex operation and are more efficient and reliable. Compare with byte-oriented protocol.
A communication protocol that does not recognize character boundaries or special protocol characters. The data is interpreted as sequence of bits.
Bit-oriented protocol is a communications protocol that sees the transmitted data as an opaque stream of bits with no semantics, or meaning. Control codes are defined in terms of bit sequences instead of characters. Bit oriented protocol can transfer data frames regardless of frame contents.
