Client side and server side

Question

Please someone should give me a understandable explanation on both of them

Answer 1

Website scripts run in one of two places – the client side, also called the front-end, or the server side, also called the back-end. The client of a website refers to the web browser that is viewing it. The server of a website is, of course, the server that hosts it.
