What is Web Server?

A web server is a system that serves the web pages (include content, images, etc.) to a web browser. A web server comprises the physical server, server system software (Apache or Microsoft’s IIS or other) and server OS (Windows or Linux or other).

A web browser communicates with the web server via HTTP. Whenever a web browser sends an HTTP request to a web server, the web server responds with HTML webpages and some additional information like java applets and others.

The web servers are the basic blocks on which a web hosting company works. You can find more by reading How Does Web Hosting Works?

The Web Services Description Language (WSDL) forms the basis for the original Web Services specification. The following figure illustrates the use of WSDL. At the left is a service provider. At the right is a service consumer. The steps involved in providing and consuming a service are:
1. A service provider describes its service using WSDL. This definition is published to a repository of services. The repository could use Universal Description, Discovery, and Integration (UDDI). Other forms of directories could also be used.
2. A service consumer issues one or more queries to the repository to locate a service and determine how to communicate with that service.
3. Part of the WSDL provided by the service provider is passed to the service consumer. This tells the service consumer what the requests and responses are for the service provider.
4. The service consumer uses the WSDL to send a request to the service provider.
5. The service provider provides the expected response to the service consumer.
 
A web server is a program that uses serve the file that from webpages to users and response to their user request, which are forward by their computer HTTP cliens. Every web server has an IP address and possible web domain name.
