Carrier Sense Multiple Access (CSMA) is a network protocol used to efficiently share a transmission medium among multiple nodes. It helps devices avoid collisions on the network by checking if the channel is busy before transmitting data, reducing the likelihood of data packets interfering with each other.

What process could be used to purify potassium chloride?
Crystallization/recrystallization process can be used.
What is the name of the process used for purification of zirconium?
The process used for the purification of zirconium is called the Kroll process. This process involves converting zirconium tetrachloride into metallic zirconium through a reduction process using magnesium.
What do data collisions do?
Data collisions occur when two devices attempt to transmit data over a network at the same time, leading to data packets becoming corrupted or lost. This can result in slower network speeds and increased retransmissions, impacting the overall efficiency of the network. To prevent collisions, network protocols like CSMA/CD are used to manage data transmissions.
What process and produces mRNA?
The process that produces mRNA is known as transcription. In this process a single DNA strand is used to make a copy of mRNA.

What mechanism is used by wireless technologies to avoid collisions in the wireless domain?
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance)
Which access method is used on an 802.11g network?
Csma/ca
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.

Mechanisms used on Ethernet networks to control access to transmission medium?
Csma/cd
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
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 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
