Answer 1

Client side programming is for web programming and it uses code that runs on the computer of someone who visits a website. It is executed by the web browser, not the web server. For instance, Javascript is read and executed by your web browser. This language can make html pages more interactive to the visitor and save data locally (like cookies). Other web languages, such as PHP, Ruby, etc, are run on the web server itself. A visitor can turn off Javascript in the browser, but server side languages are more secure and are often used for things such as reading and writing to servers and databases.
