Server
Servers, popularly known as web servers are a significant entity that plays a pivotal role in the functioning of World Wide Web. In technical terms, the primary function of a web server is to deliver web pages after processing the request to clients. The requests come to the servers in the form of HTML documents with the help of images, style sheets and scripts. A client web browser initiates communication to the server using HTTP and the server responds with the content.
If server finds itself unable to process the request, an error message is reflected on the client browser against the request. Many of the web servers like Apache HTTP Server and PHP support server-side scripting. That simply means the execution behavior of the web server is scripted in separate files. Apache and IIS are two most prominently used web servers by the web hosting administrators these days.
