Framing in the Data Link Layer

Data-link layer framing is a critical process in networking that enables reliable data transmission across diverse media. The data-link layer takes packets from the Network Layer and encapsulates them into frames, the fundamental data units for network communication. If a packet is too large for a single frame, it may be divided into smaller frames...
