The mandatory mechanism for media access control in the 802.11 standard is CSMA/CA+ACK. This mechanism is used to avoid collisions in wireless transmissions by requiring nodes to wait for a clear channel before transmitting and to acknowledge successful transmissions. RTS/CTS is an optional mechanism for handling hidden node problems, and CSMA/CD is used in wired networks to detect collisions. MAC (Media Access Control) is a broad term used to refer to the entire layer responsible for controlling access to a network medium.
