Web Servers

What is a web server?

A web server is a system that delivers content or services to end users over the internet. A web server consists of a physical server, server operating system (OS) and software used to facilitate HTTP communication.

A web server is also known as an internet server.

Main purpose

A web server is simply a powerful computer that stores and transmits data via the internet. When someone visits a web page on your site their browser communicates with your web server, sending and receiving information that ultimately dictates what appears on the visitor’s computer screen.

Thus, the main purpose of a web server is to store and transfer web site data upon the request of a visitor’s browser
