Key Concepts

Token Passing

Token passing is a media access control method in which a token, a special data packet, is passed from one network device to another. A device must possess the token before it can transmit data, ensuring orderly access to the communication medium and preventing collisions.

Media Access Control (MAC) Protocols

MAC protocols are methods used to control how devices on a network access the shared communication medium. They ensure that transmissions do not interfere with one another by implementing various strategies, including token-passing and carrier-sense techniques, thereby coordinating network communications.

Carrier Sense Multiple Access with Collision Detection (CSMA/CD)

CSMA/CD is a protocol that allows devices to listen to the network before transmitting and to detect collisions if multiple devices transmit simultaneously. Commonly used in Ethernet networks, it requires devices to stop and back off before attempting to retransmit in the event of a collision.

Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA)

CSMA/CA is a mechanism used to prevent data collisions before they occur, particularly in wireless networks. It operates by having devices check the channel for availability and often involve mechanisms such as acknowledgments to avoid collisions during transmission.
