Question

With the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly.

In the box below enter the maximum value of K for 20th collision.
(Enter only a numeric value)

Answer 1

The CSMA/CD protocol is used in Ethernet networks to avoid collisions. The maximum value of K for the 20th collision can be calculated using the formula: K for the 20th collision = 2^19K.

Step-by-step explanation:

The CSMA/CD protocol is used in Ethernet networks to avoid collisions between different devices that want to transmit data simultaneously. When a collision occurs, the adapter waits K. 512 bit times before attempting to retransmit the data. For each collision, a random value of K is drawn.

To calculate the maximum value of K for the 20th collision, we need to understand that each time a collision occurs, the value of K is multiplied by 2. So, the maximum value of K for the 20th collision can be found using the formula:

1. K for the 1st collision = K
2. K for the 2nd collision = 2K
3. K for the 3rd collision = 2(2K) = 2^2K
4. ...
5. K for the 20th collision = 2^(20-1)K = 2^19K

Therefore, the maximum value of K for the 20th collision is 2^19 times the delay after the first collision.
