The maximum time that the adapter waits until sensing the channel again for a 100 mbps broadcast channel is 0.512 ms. When two devices on the same half-duplex Ethernet network try to send data at precisely the same time, it results in a collision.
What is a collision in Ethernet?
- On a half-duplex Ethernet network, a collision occurs when two devices on the same network attempt to communicate data at the same time.
- The network "collapses" the two transmitted packets, resulting in the network discarding both of them. Collisions are unavoidable on Ethernets.
- A collision is a brief interaction between two or more bodies that alters the motion of the bodies involved as a result of internal forces at work.
- Collisions necessitate the use of force (there is a change in velocity). When two devices on the same half-duplex Ethernet network try to send data at precisely the same time, it results in a collision.
A 100 Mbps broadcast channel has a waiting time of 0.512 ms.
Remember that the CSMA/CD protocol requires the adapter to wait K 512 bit times after a collision.
Where K is drawn randomly. For K = 100,
The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms
The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms
Waiting time for a 10 Mbps broadcast channel is
K × 512 × 0.0001 = 5.12 ms
Waiting time for a 100 Mbps broadcast channel is
K × 512 × 0.00001 = 0.512 ms
The maximum time that the adapter waits until sensing the channel again for a 100 mbps broadcast channel is 0.512 ms.
