Carrier sense multiple access with collision detection (CSMA/CD) is a computer connection access strategy in which: a carrier detecting scheme is deployed, then a data station that detects another signal while transmitting a frame, sends forth a jam signal, and then delays the next release only to resend the frame at a random time. CSMA/CD is an access technique and not a procedure of the OSI replica.

When one desires to send some set of data, the following algorithm is applied. The frame is checked to whether it is ready to transmit data, the second step is to check if the medium to be used for transmission is ready if it is, the data is sent, and if not one has to wait until it is ready to transmit the data. If it is prepared the information is transmitted. The other step is to check whether a collision will occur if a collision has occurred one checks the crash sensing method. The last step is to rearrange retransmission counteracts and end frame broadcasts.

The method/criteria of checking for a collision is as follows: first, carry on with the broadcasts until the least amount sachet time is arrived at to guarantee that all beneficiaries identify the rear-ender. Then one increased retransmission contradicts. One should ensure that the highest level of broadcast efforts were arrived at. If it was reached one should abort the broadcast. Lastly, one should work out and linger in the unsystematic backoff phases in relation to the occurrence of collisions. One should also Re-enter central methods at stage 1.
