Data Link Control : HDLC & PPP in Data Communication and Networking

Data Link Control (DLC) ensures reliable data transfer over a communication link. HDLC (High-Level Data Link Control) is a bit-oriented protocol that provides error detection, flow control, and framing in synchronous networks. It is widely used in WANs due to its efficiency and reliability. PPP (Point-to-Point Protocol), on the other hand, is a byte-oriented protocol used for direct communication between two nodes. It supports authentication, compression, and error detection, making it ideal for dial-up and broadband connections. Both protocols play a crucial role in maintaining reliable data
