What is a backend

The backend is a necessary part of a mobile app that stores, secures, and processes the data. A backend app is like a server for the users to sort the required information.

If its a simple, static website, the answer is no . Just upload all your local files to your web server using FTP or the File Manager in your Cpanel.

Front end development uses HTML, CSS and other client side technologies like JavaScript to make the website look like it does. It is the back end programming that creates the logic to give your website functionality. Not all websites need or utilize back end programming .
