Which layer of the OSI model defines how data is formatted for transmission and how access to the physical media is controlled?

The data link layer of the OSI model, which is Layer 2, defines how data is formatted for transmission

and controls access to the physical media. This layer is responsible for the node-to-node delivery of

data and handles error detection and correction from the physical layer. It also manages the way data

packets are sent over the network, including the framing, addressing, and flow control. The data link

layer ensures that messages are delivered to the proper device on a LAN using hardware addresses

(MAC addresses) and translates messages from the network layer into bits for the physical layer to

transmit
