Web Servers - Javatpoint
Web pages are a collection of data, including images, text files, hyperlinks, database files etc., all located on some computer (also known as server space) on the Internet. A web server is dedicated software that runs on the server-side. When any user requests their web browser to run any web page, the webserver places all the data materials together into an organized web page and forwards them back to the web browser with the help of the Internet. Therefore, we can conclude that: -
This intercommunication of a web server with a web browser is done with the help of a protocol named HTTP (Hypertext Transfer Protocol). These stored web pages mostly use static content, containing HTML documents, images, style sheets, text files, etc. However, web servers can serve static as well as dynamic contents. Web Servers also assists in emailing services and storing files. Therefore it also uses SMTP (Simple Mail Transfer Protocol) and FTP (File Transfer Protocol) protocols to support the respective services. Web servers are mainly used in web hosting or hosting the website's data and running web-based applications.
The hardware of the web servers are connected to the Internet that manages the data exchange facility within different connected devices. In contrast, the software of web server software is responsible for controlling how a user accesses delivered files. Typically, web server management is an ideal example of the client/server model. Therefore, it is compulsory for all computers that host websites (whether with state or dynamic web page content) to have web server software.
The term web server can denote server hardware or server software, or in most cases, both hardware and software might be working together.
Whenever any web browser, such as Google Chrome, Microsoft Edge or Firefox, requests for a web page hosted on a web server, the browser will process the request forward with the help of HTTP. At the server end, when it receives the request, the HTTP server will accept the request and immediately start looking for the requested data and forwards it back to the web browser via HTTP.
