A server in a web is like a repository which holds the details of associated to your request, we use HTTP for making request and generating response.

The web server can be called to a device a terminal that provides the potential to handle the requests and provide the response.

The very basic functionality of the web server is to store the data manipulate it  then send it to the client as response using the protocol HTTP.

Pages delivered are most frequently HTML documents, which may include images, style sheets and scripts in addition to text content.

The user agent is a web browser where we made the request by using the HTTP protocol or it will disaply an error message if the request cannot be made at that time.

The resource is typically a real file on the  secondary storage of the server, but this is not necessarily the case and depends on how the web server is implemented.

While the primary function is to serve content, a full implementation of HTTP also includes ways of receiving content from clients. This feature is used for submitting web forms, including uploading of files

 Features

• Virtual hosting to serve many web sites using one IP address

• Large file support to be able to serve files whose size is greater than 2 GB

• Bandwidth balancing to limit the speed of responses in order to not saturate the network and to be able to serve more clients

• Server-side scripting to generate dynamic web pages, still keeping web server and website implementations separate from each other
