Thread: Difference Server-side and Client-side

I am learning programming language like asp.net, C++, SQL.I want to know what is the difference between Server-side and Client-side code. Any help would be highly appreciated.

Server side code get executed on the web server in the response of request for any aspx page
where client-side code get executed on the client browser (e.g. validation of controls, dynamically hiding and displaying some of controls or their values etc)
