5 Consider sending voice from Host A to Host B over a packet-switched network for example Internet phone Host A converts analog voice to a digital 64 kbps bit stream on the fly Host A then groups the

Each packet contains 48 bytes or 384 bits (48 bytes x 8 bits/byte). The transmission rate of the link is 1 Mbps or 1,000,000 bits per second. Therefore, it takes 384/1,000,000 seconds to transmit one packet, or 384 microseconds.

The propagation delay is 2 milliseconds or 2,000 microseconds.

So, the total time for a bit to travel from Host A to Host B can be calculated as follows:

Time to transmit one packet + propagation delay = 384 microseconds + 2,000 microseconds = 2,384 microseconds

Therefore, it takes 2,384 microseconds or 2.384 milliseconds for a bit to be created at Host A and decoded as part of the analog signal at Host B
