Hi Diaa,

 

Server side validation occurs at server. The benefit of having server side validation is that if the user somehow bypasses the client side validation (accidentally or deliberately), then we can catch the problem on the server side. So having server side validation provides more security and ensures that no invalid data gets processed by the application.
