What Is a Web Server?

A web server is a software that is running on dedicate, virtual or embedded server, which is capable of delivering the requested data made through the web. Typically web server’s task is to process and deliver the requested information (website contents and data) that is stored on the server. Thanks to uptick in internet of things (IoT) adaptation the web server is embedded in smart devices such as wireless security camera, fridge, and thermostat so that you can manage and monitor your devices on your network.

Some of the well-known web servers are Apache, NGINX, and IIS; the most common communication protocol used between the browser and the web server is Hypertext Transfer Protocol (HTTP). Once the web server receives your request it will fetch the requested data (document, Image or files) and send it backs to the browser.
