What is HDLC?

HDLC (High-Level Data Link Control) is a bit-oriented synchronous data link layer protocol. It is widely used for communication over point-to-point or multipoint links. HDLC provides reliable data transfer through error detection and correction mechanisms, and it defines frame structures and procedures for data transmission and control.
