HDLC (High-Level Data Link Control)

HDLC (High-Level Data Link Control) is a protocol used in digital communications to enable reliable data transfer between two devices. It organizes data into frames, adds error-checking information, and manages how data flows between sender and receiver. Think of it as a set of rules that ensures your information moves accurately and efficiently over networks, such as between computers or network equipment. HDLC provides error detection and correction, ensuring data integrity, and controls the start and end of data transmissions, making communication more reliable and orderly.
