Absolute bandwidth is the relative bandwidth of the signal (B) times the center frequency (f0).
For example , by increasing the center frequency, the relative bandwidth is unchanged, but the absolute bandwidth is increased due to increasing the center frequency.
I hope it is helpful :-)

Does it help your bandwith if you unplug your modem from time to time?
In general, unplugging your modem will not have any impact on your network bandwidth. However, there are occasions when restarting your modem will increase the amount of network bandwidth available to the computers on the network. It is possible for the internal software (or firmware) of the modem to enter an inconsistent state, resulting in less effective bandwidth caused by corrupt or lost network data. In most cases, unplugging the device causes it to restart and full bandwidth is restored.
Refers to the amount of data that can be transmitted over a communications medium at one time?

What is the bandwidth of a signal composed of frequencies from 50 Hz to 500 Hz?
The bandwidth of a signal is the width of frequencies between the highest and the lowest frequency. So 500Hz - 50Hz = 450Hz bandwidth. AE7HD
What is bandwidh?
It's easiest to compare bandwidth to plumbing. Bandwidth is basically how big the pipe is, which means if you have high bandwidth, you can usually have a lot of information going through the "pipe". If you have low bandwidth, think of having a narrow pipe (like a straw) which restricts the amount of information that can pass through at one time.
Why is it that voice and video traffic is often sent over TCP rather than UDP in todays Internet?
This is because some firewalls give less preference to UDP traffic. So its kind of a hack to get more effective bandwidth.
