What happens in csma CD when a node detects that its datahas suffered a collision?
It signals to the network that its data was damaged in a collision, waits a brief period of time before checking the network for activity, and then retransmits the data.

Which access method is used by Ethernet?
CSMA/CD: Carrier Sense Multiple Access / Collision Detection.
Which is an access method in which collision is entirely avoided?
Csma/cd
What is the difference between csma CD and csma ca - 42k?
*** In CSMA/CD it detects that a collision take place and resend the frame that was send. On a wirless network losing bandwidth along with time to detect that a collision took place was not acceptable , so CSMA/CA was utilized. ** CSMA/CD can achieve above 70% efficiency under heavy loads compared to CSMA/CA that can only achieve up to 30% efficiency under heavy loads. CSMA/CA network: A network in which the medium access control protocol requires carrier sense and where a station always starts transmission by sending a jam signal; if there is no collision with jam signals from other stations, it begins sending data; otherwise, it stops transmission and then tries again later. CSMA/CD network: A bus network in which the medium access control protocol requires carrier sense and in which exception conditions caused by collision are resolved by retransmission
What mechanism is used by wireless technologies to avoid collisions in the wireless domain?
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance)
Does Ethernet uses CSMA CA?
No, Ethernet does not use Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). Instead, Ethernet employs Carrier Sense Multiple Access with Collision Detection (CSMA/CD). In CSMA/CD, devices listen to the network before transmitting and can detect collisions that occur, allowing them to retransmit after a random delay. CSMA/CA is primarily used in wireless networks, such as Wi-Fi, to help prevent collisions from occurring in the first place.
What does the acronym CSMA CD stand for?
The acronym CSMA CD stands for Carrier Sense Multiple Access with Collision Detection. CSMA CD is a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously.
How CSMA work?
Carrier Sense Multiple Access (CSMA) is a network protocol used to manage access to a shared communication medium. It operates by having devices first listen to the channel to determine if it is free (carrier sensing) before attempting to transmit data. If the channel is busy, the device will wait until it becomes free; if it’s clear, the device sends its data. To prevent collisions, CSMA may use techniques like CSMA/CD (Carrier Sense Multiple Access with Collision Detection) or CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance).
What is the access method use by Wireless LAN?
WAPs use CSMA/CA - Carrier Sense Multiple Access with Collision Avoidance.
What is the primary function of csma CD in an Ethernet network?
it prevents the collision between the data that is sended by the network cards over ethernet networks
What is a common characteristic of both csmacd and csmaca?
A common characteristic of both Carrier Sense Multiple Access with Collision Detection (CSMA/CD) and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is that they are both network protocols used to manage how multiple devices share a communication channel. They operate on the principle of "carrier sensing," where devices listen to the channel before transmitting data to minimize collisions. While CSMA/CD is primarily used in wired networks and deals with collisions after they occur, CSMA/CA is used in wireless networks and aims to prevent collisions from happening in the first place.
