Web Server

What is Web Server?

Web server is server software that runs websites. It can satisfy client requests on the World Wide Web by delivering web pages to the browser. The general purpose of a web server is to store, process, and deliver web pages to users.

The communication between client and server is done by using the Hypertext Transfer Protocol (HTTP). These web pages are mostly static content of HTML documents which include style sheets, images, scripts for text content, etc, A web server also supports server-side scripting using Hypertext Preprocessor (PHP), Active Server Pages (ASP) and other scripting languages. Apart from HTTP, a web server can also support Simple Mail Transport Protocol (SMTP) for emailing, and File Transfer Protocol (FTP) for file transfer and storage.

When a website is developed, it was hosted on the webserver, to make it available for other users to see. The website will open in browsers like chrome, Mozilla Firefox, Opera, and Internet Explorer. Users can able to access the website by its unique web address (domain address). Each website has its own domain address. For example, www.example.com/home is a domain address. If the webserver is down, then the web page will not load.
