Often confused with its hardware counterpart, a web server is a software application that plays a critical role in the web hosting process. As the name indicates, it helps the server hardware serve your web pages when they are requested by a visitor’s web browser.
Web servers run a method known as HTTP (HyperText Transfer Protocol), a standard communications procedure that utilizes the client-server model to facilitate communication between remote computers. For example, when a visitor opens your website in their browser, which is a client program, a request is sent to the server hosting your site. The server application then processes that request and responds accordingly, displaying your web page to the visitor. There are many types of web servers, but the most prominent on the web hosting market are Apache and Microsoft IIS (Internet Information Services).
