Logical Link Control (LLC)

Logical Link Control (LLC) is a sublayer of the Data Link layer in computer networking that manages how data packets are sent over a network. It helps devices communicate by identifying the type of data being transmitted and ensuring that it arrives correctly. LLC provides services such as error checking and flow control, allowing multiple higher-level protocols (like TCP/IP) to use the same physical network link efficiently. Essentially, LLC ensures reliable communication and helps devices understand each other, making the network more organized and effective.
