Networking questions
... Suppose the effective bandwidth of the cable between the two is 10 Mb/sec. A wants to send a file of size 5kb. After B receives the file, it sends a one-bit acknowledgment back to A. How long would A take to transmit the file? How long does A need to wait to receive the acknowledgement from B? What ...

If some other interface is transmitting there will be a signal on the channel, which is called carrier. All other interfaces must wait until carrier ceases before ...
