WebMar 22, 2024 · Conclusion: Controlled access protocols play a crucial role in managing access to shared resources in computer networks. Reservation, polling, and token passing are three widely used techniques for implementing controlled access protocols. While each of these techniques has its advantages and disadvantages, the choice of the protocol … Carrier-sense multiple access (CSMA) is a medium access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus or a band of the electromagnetic spectrum. Under CSMA, a transmitter uses a carrier-sense mechanism to determine whether another transmission is in progress before initiating a transmission. That is, it tries to detect the presenc…

WebThe importance of the token ring topology is, the source sends an empty token with a message and address of the destination. So the token checks for the successive node i.e. address of computer/ host. When the token identifies the node, the receiver copies the data and returns with a receipt containing the source’s address.

In a local Ethernet network (IEEE 802.3), all network participants usually meet on a common transmission medium – a cable. This meeting must be regulated to avoid chaos during data transmission, which could lead to data loss or damage. CSMA/CD offers a method that organizes data transmission properly.

Protocols like CSMA/CD and CSMA/CA nullifies the possibility of collisions once the transmission channel is acquired by any station. However, collision can still occur during the contention period if more than one stations starts to transmit at the same time.
