What is Apache?
Apache HTTP Server is a free and open-source hypertext transfer protocol (HTTP) web server commonly used on Unix, Linux, and Solaris platforms. Created by American software developer, Robert McCool, it was released in 1995 and quickly obtained a majority hold on the web server market. The primary advantage of Apache is that it is generally free and typically packaged as one-fourth of the LAMP stack.
Apache is currently one of the most widely-used web servers on the Internet and is very secure, fast, and reliable. The Apache web server application helps serve web content that is accessible through the Internet. Apache accepts directory or HTTP requests from Internet users and sends the desired information back in the form of files and Web pages.
What is the Function of a Web Server?
A web server is a program used to store, process, and deliver web pages. The basic function is for web hosting, and the protocol used for the web pages is HTTP.
When users search for website files in the web browser address bar, the web server takes the request over the Internet to its respective server. From there, it returns the target files to the web browser from which they were searched.
