Answers:

Client-side is faster than server-side as the networking time from client to server is saved
server-side is done on the server. Then the server converts the data into an html page and sends to the browser.
server-side is more secure as the user cannot see the code even he does a view-source.

Client side validation is processed the client side before submitting the form. The advantage of using the client side validation is it reduces the netork trafiic since the validation is processed in the client machine itself. Eg email isnumeric isdate etc.

Server side validation is processed in the server. Some data cannot be validated in the client side and it has to be validated in the server side. Eg Date between the two dates in the database.
