What is the primary function of the Media Access Control (MAC) layer on transmission?

• Assemble data into a frame

• Provide interface to higher levels

• Perform flow and error control

• Disassemble frame

How does a station decide to send data in a Random Access MAC protocol?

• It sends data whenever it wants.

• It uses a procedure defined by the protocol.

• It waits for a superior station to give permission.

• It sends data only when the medium is busy.
