the process of replacing fixed value with parameter is calles parameterization
types of parameterization:
1) data table
2) test/action
3) environment variable

output parameter :-aloows u to use output to capture values frm application runtime
random number :- quick test can generate random numbers and input them as values for a parameter
environment variable :- quick test can insert a value frm the environment variable list.these values can be either quick test related or they can related to the system environment
