Which access method is used by Ethernet?
CSMA/CD: Carrier Sense Multiple Access / Collision Detection.
How does csma minimize fading?
How does CSMA minimize fading?
Distinguish between persistent and non persistent CSMA?
Pesistentent CSMA sense the channel continuously where as non pesistent CSMA resense the channel after a time decided randomly or based on probabilistic work----- Sanjay Bhaumick
Describe one protocol used for Local Area Network?
IP, appletalk, token ring, CSMA/CD, CSMA/CA
To 802.11 standard IEEE specifies what type of access method?
Network+ Guide to Networks answer: Csma/ca
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.
What mechanism is used by wireless technologies to avoid collisions in the wireless domain?
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance)
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
CSMA stands for?
carier sense multiple access
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
