a channel is actually a path through which a signal of a particular frequency travels and bandwidth is the capacity of that path it tells about the number or range of frequencies which a path can carry
The basic relationship is that the two together form some kind of constant wherein you cannot have more of one without giving up some of the other. Want more gain? You'll have to work with a narrower bandwidth. Want more bandwidth? You will have to sacrifice some gain to get it.
Yes, if you have the required talents and qualify for the position you are seeking.
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.

The transmission bandwidth refers to the range of frequencies that are being transmitted from one point to another. The channel bandwidth on the other hand refers to the frequencies of a given channel.
I'm afraid you will need to specify on what exactly are you referring to. We could be talking about a radio channel bandwidth, a computer data transfer channel bandwidth or even a radio communications channel bandwidth. It is difficult to tell with the narrow question you posed.
Low pass channel or medium with the bandwidth that starts from zero.Band pass channel has the bandwidth that does not start from zero.
The coherence bandwidth of a wireless channel is the range of frequencies that are allowed to pass through the channel without distortion.

In-Band Signaling (IBS)
is the set of standard rules for data representation, signaling, authentication and error detection required to send information over a communications channel
In-channel signaling is also often referred to as in-band signaling. See http://en.wikipedia.org/wiki/Signalling_(telecommunications)#In-Band_versus_Out-Of-Band and http://en.wikipedia.org/wiki/In-band_signaling.The signaling used to establish and tear down a phone call was located in the same physical communication channel used to carry the call (i.e voice, fax or modem) traffic, and used DTMF tones. Examples are CCITT Signaling Systems 1-5 R1 & R2. Most books on SS7 should talk briefly about this.SS6 & SS7 moved to take the signaling out-of band, and to establish a common channel for all signaling in digital packet-based format (non-tone based) allowing one signaling channel to control a large number of "voice" circuits.
no of sources: 5 bandwidth required for each source= 400 Hz no of guard times= 5 bandwidth of each guard time = 200 Hz minimum bandwidth = 5 *400 + 5*200 Hz
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .
