When you use a social network online or read this article, then you can say that you are using one or more web servers. Web servers are the basic components of today’s Internet and actually connect users to the website they want. In the following, we will pay more attention to the category of web servers.
What do web servers do?
Web servers receive a user request and then respond to it. Web servers have hardware that carries data, and in terms of software, they also have the operating system and software of web servers. Web servers use various protocols such as HTTP or HTTPS to meet the needs of users.

Webserver
A protocol includes a simple mail contract (SMTP) and a file transfer protocol (FTP). Web servers are also computers, but they are only designed to achieve a single goal, and of course, they also need hardware. A web server’s hardware can be as powerful as a supercomputer used in Google or your laptop. Its operating system can also be Windows, Linux, or macOS. You can communicate with the server through the software layer.
In its simplest form, a web server consists of an HTTP server, a database, and at least one programming language. All of these work together so that one server can request web pages and connect to other servers online if needed.
How a web server works web server
You can communicate with web servers via URLs or domain names. The software layer does the processing and translation work. In this process, languages such as PHP, Python, Ruby, or Java are used to request a web page. The server then uploads all the requested files (rich media files, images, JavaScript files, and HTML web pages) to its database and then sends them to your browser.
All you have to do is enter the correct server position or URL. Using the URL, your browser finds the IP address of the entered domain through DNS. After receiving and confirming the request by the web server, the desired web page will be sent to the user. For example, if you do not have access to a page, you will encounter an error message instead of receiving it.

Compare internal and remote web servers
Web servers are also a type of hardware and must be physically present somewhere. Now if a server is outside the user’s location, then it is called a remote server. Concerning internal servers, you can also turn your laptop, desktop, or tablet into a web server so that others can access your website through them. You can also purchase a dedicated server and maintain it yourself.
You should also be careful about the type of web server. For example, file servers do not provide access to websites but are only used to store digital files and documents. Similarly, you can use a file server alongside a web server, but you can not use the latter to host a complete website.
