MAC (Media Access Control)

Media Access Control (MAC) is a set of rules that govern how devices on a network communicate and share data without interference. It ensures that only one device transmits at a time, preventing data collisions and maintaining efficient data flow. Think of it as a traffic controller for network communication, coordinating when each device can send or receive information. MAC is essential for local networks (like Wi-Fi and Ethernet), enabling multiple devices to connect and share resources smoothly. It operates at a specific layer to manage access and maintain orderly data exchange among connected devices.
