Description: Logical Link Control (LLC) is a sublayer of the data link layer in the OSI model that manages protocol data units. Its main function is to provide a means for different network protocols to coexist and communicate over the same physical medium. LLC acts as an intermediary between the data link layer and the network layer, allowing devices of different types to communicate seamlessly. This sublayer is responsible for protocol identification, media access control, and error management, ensuring that data is transmitted efficiently and reliably. Additionally, LLC enables the multiplexing of different protocols, meaning multiple types of traffic can be sent and received simultaneously over the same physical connection. This is especially important in modern networks, where multiple protocols such as IP and others are used. In summary, Logical Link Control is essential for interoperability and efficiency in network communications, facilitating data transmission between heterogeneous devices.
