Web server is a server software, responsible for putting a website on the Internet. To do this, the Web server acts as an intermediary between the user (client) and the server (server). When a user visits a page, the web server helps the user to send this request to the server. At the same time will take all feedback from the server forward to the user.

3. How does Apache Web Server work?
Apache is a web server, but not a physical server, but a piece of software running on the server. Apache is a cross-platform software that works well with Unix and Windows servers.
When a user visits a page on your website (home page, about, ...). The user browser will send this request to the server and Apache will return the result with all the files that make up the requested page (images, text, ...). The server and client communicate with each other over the HTTP protocol, and Apache is responsible for making sure this process is complete and secure between the two machines.
Apache is also a highly customizable and precise modular platform. Modules will allow the server admin to perform modes such as enabling or disabling functions. Apache with the use of security modules functions caching, absolute password authentication. You can also configure your own server by configuring the .htaccess file.
