As people began to realize the effectiveness of transferring data across what is now known as the internet, multiple operating systems began to develop so that all industries, and eventually the public, could exchange data using computers. If you run a website, it is important to understand what web servers are, how they operate, and what role they play in delivering your website content to site visitors. It's possible you've never thought about what happens when you enter a URL into your computer's browser or click on a website found in a search result. In fact, you may just think that when websites appear on your computer screen, it is the result of some kind of technological magic. And for the most part, this is okay if you are a casual internet user who enjoys simply browsing and finding information that interests you. This knowledge will help you have a better understanding of how your site's data is delivered to site visitors and even help you choose the right web hosting company to store all of your site's data. Web servers are programs that use HTTP Hypertext Transfer Protocol to serve the files that form web pages, such as the ones that make up your website, to site visitors when they click on your site or enter your site's URL into their web browser. They can deliver the same files, or different ones, to hundreds of site visitors at any given time. They are also a part of a larger web of programs that help serve emails, download File Transfer Protocol FTP files, and build and publish web pages such as the ones you have on your site.

Web Servers and Hosting
A web server is computer software and underlying hardware that accepts requests via HTTP , the network protocol created to distribute web pages ,  or its secure variant HTTPS. A user agent , commonly a web browser or web crawler , initiates communication by making a request for a specific resource using HTTP, and the server responds with the content of that resource or an error message. The server can also accept and store resources sent from the user agent if configured to do so. A server can be a single computer, or even an embedded system such as a router with a built-in configuration interface, but high-traffic websites typically run web servers on fleets of computers designed to handle large numbers of requests for documents, multimedia files and interactive scripts. A resource sent from a web server can be a preexisting file available to the server, or it can be generated at the time of the request by another program that communicates with the server program. The former is often faster and more easily cached for repeated requests, while the latter supports a broader range of applications. Websites that serve generated content usually incorporate stored files whenever possible.
