A jam signal indicates that the collision has cleared and the media is not busy.
X A device listens and waits until the media is not busy before transmitting.
The device with the electronic token is the only one that can transmit after a collision.
X All of the devices on a segment see data that passes on the network medium.
X After detecting a collision, hosts can attempt to resume transmission after a random time delay has expired.

What are three characteristics of CSMACD?
Devices listen to the media and transmit data only when they cannot detect another signal on the media. All devices on the media can hear all communications When a collision occurs, all devices stop transmitting for a randomly generated period of time.
Which access method is used by Ethernet?
CSMA/CD: Carrier Sense Multiple Access / Collision Detection.
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.
Characteristics of Ethernet 802.3?
1. Based on the CSMA/CD process 2. Specifies the MAC portion of the data link layer (layer 2)
Which Ethernet standards supports csma CD?
10BaseT
Why csma CD not applicable in mobile ad hoc networks?
Because CSMA/CD does not prevent Hidden terminal problem. so it is onlly applicable in Wired networks.
Which is an access method in which collision is entirely avoided?
Csma/cd
Describe one protocol used for Local Area Network?
IP, appletalk, token ring, CSMA/CD, CSMA/CA
Which are two characteristics for Ethernet standard?
The CSMA/CD access method is used to detect collisions Data transmission is via frames, each having a single MAC address
What are characteristics of the Ethernet data transmission standard?
Data transmissions is via frames, each having a single MAC address. The CSMA/CD access method is used to detect collisions.
Which is a drawback of the CSMA CD access method?
Collisions can decrease network performance.
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
