Can I ask few basic questions related to Bode plots?

1) Are Bode plots based on Laplace transform?

2) What do Zeros and Poles signify?

Do they signify frequencies?

3) Further, if answer to 2) above is frequency, are Zeros frequency points where output is Zero

If this is true then what does poles signify?

4) I am also interested to find out how transfer functions for a given circuit can be determined (both in time domain and S domain)

Thanks a lot ...
