What are webserver??
In simple terms web server is a computer that stores, processes, and delivers website files to users browser. Here they uses Hypertext Transfer Protocol (HTTP) to respond to user's request via internet.
What is a web server made of?
It consists of a Hardware & Software side, were each of those playing different roles in processing files.
On the hardware side, a web server connected to the internet 24/7, which enables it to exchange data or files between other devices which are likewise connected. This data can come in different forms, such as HTML files, images, JavaScript files, or CSS stylesheets. Web server hardware also stores web server software.
- Web server software controls how web users access hosted files. It consists of several components, housing at least an HTTP server. An HTTP server is software that can understand HTTP requests and URLs.
Working of web server
When a web user wants to load a website’s content, their web browser requests access through the internet. Which is called an HTTP request. Now the web browser looks for the requested website’s IP address by translating the URL of the web pages via the Domain Name System (DNS). This process locates the web server where the site’s files are hosted.
As the web server receives the HTTP request and processes it through its HTTP server. Once its HTTP server accepts the request, it will search through server files to obtain the relevant data.
After that, web server returns the site files to the web browser that sent the request. Then, the web user sees the website content.
That's all the about it all this process take few milliseconds to complete.
- Some of most commonly used web server are Apache, Nginx, Microsoft Internet Information Services (IIS), etc.
What Is Apache?
Apache is a free and open-source software that allows users to deploy their websites on the internet. It is one of the oldest and most reliable web server software maintained by the Apache Software Foundation, with the first version released in 1995.
Although we call Apache a web server, it is not a physical server, but rather a software that runs on an HTTP server. Its job is to establish a connection between a server and the browsers of website visitors (Firefox, Google Chrome, Safari, etc.) while delivering files back and forth between them (client-server structure). The Apache software is also compatible with any operating system, from Windows to Unix.
