We are using CSMA/CD with exponential backoff to send data through a broadcast Ethernet channel shared by 4 users. It takes 1 ms to send 512 bits over the channel.

User A is trying to transmit a frame and just experienced the 10'th consecutive collision on this same frame. What is the maximum amount of time (in ms) that A will wait before sensing the channel again?

Have the answer just want to know how to do it. thanks
