What is Vulnerable time in terms of CSMACD?
CSMA\CD means that when a Clint want to send a signal if is it free it will send the signal and it happens in other Clint at the same time so the signal will crash and then they will try again later after period of time.
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
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?
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 happens in csma CD when a node detects that its has 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.
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.
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.
What happens in csma CD when a node detects that is data has 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.
What is the function of CSMA on a wireless Ethernet network?
It is prevent all connected network cards sending at the same time.
Describe one protocol used for Local Area Network?
IP, appletalk, token ring, CSMA/CD, CSMA/CA
The truncated binary exponential back off algorithm?
This is the Algorithm use by CSMA/CD as a wait period to allow other devices on the network to access the media.
