what is the difference between laplace transform and z transform plz explain
 

the difference is the "S" and "Z" parameters.
S used for analog computation while Z for digital processing.
basically Z is the digital approximation of the analog frequency domain signal.
Z=exp(sT)
where T is the sampling time.
 

You must use z transform for discrete time signals and laplce transform for continous signals.
