Chapter 5, Problem 1RQ

Program Description Answer

A transmission characteristic that could not be achieved completely is bandwidth.

Hence, the correct answer is option “D”.

Explanation of Solution

Bandwidth:

The maximum amount of data that can be transmitted through transmission medium at a given period is called as bandwidth.

• It is one of the transmission characteristic, which could never be achieved completely.
• The bandwidth can be estimated using bits-per-second.
• It measures the difference between lowest and highest frequency that is transmitting in the system to calculate the total frequency.

Explanation for incorrect options:

Latency:

Latency is the measure of how many seconds a network will take to transfer a data from one device to another. This characteristic could be achieved completely while transferring the data.

Hence, the option “A” is wrong.

Throughput:

Actual amount of data that can be transmitted through transmission medium at a given period is called as throughput.

• Throughput is always lower than the bandwidth; this is because actual network speed is always lower than the specified speed.
• This characteristic could be achieved completely while transferring the data.

Hence, the option “B” is wrong.

Bit rate:

The total file size of an audio is represented using the bit rate. It is usually represented in bps. This characteristic could be achieved completely while transferring the data.

Hence, the option “C” is wrong.
