Apache is a free and open-source HTTP server. It was first released in 1995 by Apache Software Foundation. It is a cross-platform web server and can run on both Windows and Linux or Unix-like operating systems.
It runs on 67% of web servers worldwide. It is fast, secure, and reliable. It is customizable to meet the needs of different environments by using extensions and modules.
HTTPD is a software program that runs in the background of a web server and waits for incoming server requests. The daemon answers the requests automatically and serves the hypertext and multimedia documents over the internet using HTTP.
