25. What is the difference between HTML and Web server controls?
  HTML controls are client side controls therefore, all the validations for HTML controls are performed at the client side.
On the other hand, Web server controls are server side controls; therefore, all the validations for Web server controls are performed at the server side.

Server Side Controls have events which can be written in the code behind file. Server Side Controls are accessible in the code behind file. HTML Controls are a bit light weight as no rendering is performed on the server. When application need to be lightweight and more faster, use HTML controls with AJAX or REST to transfer data between server and client.
