Multiple Access Protocols (CSMA/CD, CSMA/CA)
Multiple Access Protocol (CSMA/CD)
CSMA/CD is a shared-medium bus protocol that allows multiple devices to transmit data at the same time.
Each device transmits a packet of data as long as there is available bandwidth on the bus.
If multiple devices transmit at the same time, collisions occur, and the data is lost.
CSMA/CD is used in applications where the network is shared among a large number of devices, such as a computer network.
Multiple Access Protocol (CSMA/CA)
CSMA/CA is a shared-medium bus protocol that allows multiple devices to transmit data in a controlled manner.
Each device has a unique transmission opportunity.
When a device finishes transmitting its packet, it stops transmission and listens for incoming packets.
This prevents collisions and ensures that all devices have the opportunity to transmit data.
CSMA/CA is used in applications where the network is shared among a limited number of devices, such as a home network
