The Data Link layer of the OSI model is further divided into which two sublayers?

The Data Link layer of the OSI model is indeed divided into two sublayers: the Logical Link Control (LLC) and Media Access Control (MAC) sublayers.

The LLC sublayer is responsible for error checking and frame synchronization, which allows it to communicate with the upper layers of the OSI model and manage data link layer protocols. Meanwhile, the MAC sublayer handles the framing and addressing of data packets for transmission over the physical medium. This includes defining how devices on the same network segment access the shared medium and manage conflicts during transmission.

The other options listed do not correspond to the sublayers of the Data Link layer. TCP and UDP are transport layer protocols, while IP is a network layer protocol and FTP, HTTP, and SMTP are application layer protocols. This distinction underscores the structure of the OSI model, which organizes networking functions into separate layers to manage communication effectively among devices.
