the idea of bandwidth ,bit rat and throughput in communication &differense bet them

hi guys can anyone help me to understand the (bandwidth ,bit rate ,throughput )in communication system and the difference between them ,because I'm urgently need to understand it good in communication system,i wish from u explain with shit example



thunx for all

1.

Bit rate refers to the speed at which a device/system is capable of mechanically/electronically transmitting 0's and 1's. It usually (but not exclusively) depends on the frequency at which you're transmitting.

Bit rate is often abbreviated as bps. Easily confused with bytes per second. You're supposed to understand when bps applies to bits and when it applies to bytes. Not easy to do.

2.

'Throughput' might be a concept, or it might be a specification. One could describe it as 'effective transfer rate in real life'.

Start with a raw bit rate, then add waiting times, re-tries, etc., to arrive at a working value... which we call throughput.

3.

Bandwidth usually refers to the space allocated for transmitting in a portion of the frequency spectrum.
