Carrier Sense Multiple Access

Carrier Sense Multiple Access, which also is referred with the abbreviation widely in the world of computer networking i.e. CSMA, is actually a probabilistic protocol that is known as Media Access Control or you may say MAC which is commonly used in intention of node verification. Actually the absence of a node is verified in this protocol in terms of other traffic before routing or transmitting data on a medium known as shared transmission medium.

This shared transmission medium is also include the medium known as an electrical bus as well as the medium known as electromagnetic spectrum. The fact that feedback is actually used by a transmitter from any receiver is normally described with the term “Carrier Sense” which actually detects the wave of a carrier just before the data is tried to be sent.

In other words, the presence is actually tried to be detected by “Carrier Sense” of a signal known as encoded signal from another workstation or you may say computer station before making any attempt to route or transmit data. The waiting process to transmit the data is then done by a station or workstation when the carrier is sensed.


The term “Multiple Access” is normally used in intention of describing the fact that the medium can be sued to receive as well as send the required data on multiple stations at the same time. Transmission, that normally is sent through any one node of an electric bus architecture may easily be received by all other workstations or you may say computer stations on the same medium or network architecture.
