Definition: HDLC stands for High-Density Link Control Protocol. It's a protocol used in network communication to transmit information between devices over a fixed-length data transmission medium with varying bit rates. Definition: High-Density Link Control Protocol, also known as HDLC, is a protocol for controlling link speed and quality in networking. It is designed to minimize latency and ensure that the data transfer is performed reliably. It's used for high-speed networks like Ethernet and Gigabit Ethernet (IEEE 802.3).
