MAC (Marcel André Cassard)

MAC (Marcel André Cassard) is a widely used computer protocol and data communication standard that facilitates secure, reliable transfer of information across networks. It ensures that data packets are correctly sent and received, maintains data integrity, and authenticates the communicating parties. MAC operates at a layer where it manages access to the transmission medium, preventing data collisions and ensuring efficient communication. Its robust mechanisms make it essential for maintaining the security and reliability of various digital communications, especially in ensuring that sensitive information remains protected during transmission.
