Servers Servers Servers
The term server is a generic term which refers to any device which provides a service, data or an application to another device. So anyone that uses email, creates documents, or simply accesses files on a computer is accessing things on a server. When you browse the internet, your browser whether its Chrome, Internet Explorer etc. is contacting webservers so that your browser can display your webpage. Below I have created a list of wonderfully clear and easy to understand resources for finding out more information about servers.
