What is the main function of a web server?

The main function of a web server is to store digital content and web applications. When a user requests a webpage by entering a URL in their browser, the browser sends a request to the web server that hosts the site. The server processes this request and delivers the corresponding web content, such as HTML pages, images, and other resources, to the user's browser. This process involves not just storing these files, but also handling various protocols (like HTTP and HTTPS) to ensure that the data is transmitted efficiently and securely.

The incorrect choices highlight other important aspects of the online environment but do not pertain directly to the core function of a web server. Graphic design is vital for creating visually appealing websites but is the domain of design software and tools, not web servers. Managing internet service provider connections is more related to network infrastructure than the specific tasks of a web server. Facilitating customer support inquiries is an essential function for companies but falls under customer service operations, often implemented through web applications rather than being a direct function of a server itself.
