Description: Logical Link Control (LLC) is a sublayer of the data link layer in the OSI model that manages protocol access to the physical medium of the network. This sublayer provides communication services between the network layer and the data link layer, allowing different network protocols, such as IP, to communicate effectively. LLC handles protocol identification, medium access control, and error management, ensuring that data is transmitted reliably and efficiently. Additionally, LLC enables the multiplexing of different protocols over the same physical medium, meaning multiple types of traffic can coexist on a network without interference. This capability is crucial in modern network environments where various technologies and protocols are used simultaneously. In summary, Logical Link Control is essential for interoperability and efficiency in network communications, facilitating data transmission between devices across different network technologies and manufacturers.
