What does MAC stand for?

• A. Local Area Network
• B. Metropolitan Area Network
• C. Media Access Control
• D. Megabyte

Answer: (C)

MAC stands for Media Access Control, a term used at the Data Link layer to manage how devices access the physical transmission medium and to provide hardware addressing. Each network interface card has a unique MAC address that frames use to identify the source and destination on a local network. This addressing helps switches forward frames correctly and enables multiple devices to share the same medium under proper control. The other options—Local Area Network, Metropolitan Area Network, and Megabyte—refer to network types or data size, not the abbreviation for MAC.
