Which component is NOT involved in web page delivery?

The correct answer is based on the role of each component in the web page delivery process.

In the context of web page delivery, the primary functions are typically carried out by a web server, client-side software, and a web browser. The web server hosts the web pages and serves them to clients upon request. The web browser acts as the interface through which users access and view web pages. Client-side software refers to applications that run on the user's device to interact with the web pages, such as scripts that enhance user experience.

The operating system, while necessary for managing hardware and allowing the web browser and web server to function, is not directly involved in the process of delivering web pages. Instead, it supports the execution of applications and facilitates interactions between hardware and software. Therefore, it does not play a direct role in how web content is served or presented to users.
