Random Sampling-A method of sampling in which each and every item
of the universe 
has equal chance of being selected in the sample is

called as random 
sampling
In case of systematic sampling, the data is arranged
numerically, alphabetically etc From the arranged items, every nth
item is selected as sample item For ex, every 100 out of 1000
computers are to be selected as a sample The computers will be
numbered and systematically arranged Now if we selected 100 as a
first number, the numbers after that will be like this
200,300,400,500 etc Thus Systematic sampling is a short cut method
of random sampling
