Apache is a popular open-source web server that can be used to host websites and applications. It is easy to install and configure, and it is highly customizable through the use of modules.

By default, the Apache document root (the directory where your website files are stored) is located at /var/www/html. You can place your website files in this directory, and they will be accessible through a web browser.

Note: If you are using a firewall, you may need to allow access to the Apache web server through the firewall. On Ubuntu 20.04, the firewall is managed by UFW (Uncomplicated Firewall). To allow Apache traffic, you can use the following command:
sudo ufw allow in "Apache Full".
