The main reason is that even when the full channel bandwidth is used there is always overhead required to manage the information transfer, so some of the total bandwidth will be consumed by this overhead. So only the remaining bandwidth is potentially available for throughput.
This is true for both digital and analog communication channels.
An example of overhead present in both digital and analog telephone communication channels are "alarm" signals used to report equipment failures to assist in equipment maintenance.
Some examples of overhead in computer network channels are start bits, stop bits, parity bits, CRC codes, sync bytes, and packet headers.
Also in many situations the traffic load is low for long periods of time so in those periods much of the potentially available throughput will not be made use of.

Is the greatest common factor of a pair of numbers always equal to or less?
Always equal to or less than the smaller number, yes.
The gcf if a pair of numbers is always equal to or less than the lesser of the two numbers true or false?
False
What is bandwidth in LCR connection?
The bandwidth is the difference between the frequencies at which the average power dissipated is one half the maximum value or current is 1/square root(2) times its maximum value. One frequency is greater than and the other is smaller than resonant frequency and they are symmetrical about it.
What has a measure more than 180 but less than 360?

Does Michigan have more or less farmland than Indiana?
Less
Is throughput always less than bandwifth?
Throughput in megabits per second will always be equal to or less than the bandwidth in megabits per second (it can't be higher). Throughput decreases as latency increases. For instance if you send a file to your neighbor two houses down the latency should be very low (assuming you are on the same network). However, if you send it to another city the latency will be higher and while your bandwidth remains the same, your throughput will decrease due to the latency between the locations. Note that this can be improved by optimizing the TCP window size on your computers. There is a free TCP optimizer program available on the web if you search on that term.
What is throughput in case of multiprogramming?
Slightly less than the number of processor in the system.
What are the port expander advantage and desadvantage?
Well, depending on what you are using it for there are different kinds of advantages and disadvantages. If you are using it on a desktop or home computer one of the advantages is the ability to allow more devices of a particular port type to be utilized at the same time. One disadvantage is if you have a 3Gbps port, with a port expander installed that can support up to seven devices, only has a max of 3Gbps throughput bandwidth divided by each device; or however many are plugged in and being used. The more devices you have plugged in the less throughput bandwidth that port can use.

What Occurs when downstream throughput is higher than upstream throughput?
Asymmetrical communications
What is asymmetrical communication?
In asymmetrical communication, downstream throughput is higher than upstream throughput.
How much it cost for hosting a website with 1million page view?
That depends on how much bandwidth the site uses, and your web host's pricing for bandwidth. If the site is mainly text, you can expect to use less bandwidth than if the site were hosting video or other rich media.
The telephone line the bandwidth for the voice is usually the bandwidth for data?
Because voice communication uses more information to reproduce the person's tones and qualities over the line. Data is a digital signal composed of 1 & 0 - needing much less bandwidth.
Is the remainder always greater than or less than the divisor?
It SHOULD always be less than the divisor... Otherwise your answer is wrong.
Which trigonometric functions always have values less than 1?
The sine and the cosine are always less than one.
Are negative numbers always less than their absolute value?
Negative numbers are always less than their absolute value.
Is negative 5 less than 5?
A negative number is always less than a positive number, in the exact same way that 3 is less than 4 and always will be.
