Apache 2 vs. HTTPD — What's the Difference?

Difference Between Apache 2 and HTTPD


Key Differences

Apache 2 represents the second major version of the Apache HTTP server. It is developed and maintained by an open-source community under the Apache Software Foundation. HTTPD, on the other hand, is a term that generally refers to web server software and stands for "HTTP Daemon," illustrating its purpose to handle HTTP requests.
Apache 2 has introduced many new features and improvements over its predecessor, addressing various performance and functionality aspects. HTTPD, while commonly referring to Apache's server due to its popularity, can be applied to describe other web server software, highlighting its more general usage.
In the context of software, Apache 2 is notable for its modular architecture, allowing developers to add functionality through various modules. When discussing HTTPD in a broader sense, it refers to the software handling the web server processes, with no direct implication of its features or architecture.
When discussing Apache 2, one might delve into specific features, configurations, and modules particular to this version. When discussing HTTPD, conversations might revolve around web server operations, independent of a specific server software, unless explicitly stated.
In a server environment, Apache 2 may require particular attention to its configuration, performance tuning, and module management. Alternatively, HTTPD conversations might focus on generic web server troubleshooting, maintenance, and administration, not strictly bound to Apache’s software.
