What is the functional description of Data Link in the OSI Model?

• Defines the format and organization of data, including encryption.

• Defines the electrical, optical, cabling, connectors, and procedural details required for transmitting bits.

• Refers to logical addressing, routing, and path determination.

• Formats data into frames. Defines rules for when the medium can be used and means by which to recognize transmission errors.

What is the functional description of the Transport layer of the OSI Model?

• Provides services between two host computers, including flow control, connection establishment, and error recovery.

• Defines the format and organization of data, including encryption.

• Establishes a link between the originating hub to a client, responsible authentication.

• Controls hardware devices and media that make up the network.
