What does a web server do?

A web server is the backbone of any website, handling all the requests and delivering the requested web pages to users. It plays a crucial role in ensuring that websites are accessible and functional.

Handling Website Requests

When a user types a web address into their browser or clicks on a link, their request is sent to a web server. The server processes the request and retrieves the necessary files to generate the web page. These files include HTML, CSS, JavaScript, images, and other media files.

The web server then sends these files back to the user’s browser, which interprets the data and displays the web page. This entire process happens in a matter of milliseconds, allowing users to access websites quickly and efficiently.

Storing and Serving Files

A web server acts as a storage facility for website files. It stores all the HTML, CSS, JavaScript, and media files that make up a website. When a user requests a web page, the server retrieves the relevant files from its storage and sends them to the user’s browser.

The server also handles user uploads and stores files such as images, videos, and documents. It ensures that these files are accessible and can be served to other users when requested.

Managing Website Traffic

A web server is responsible for managing website traffic and ensuring that websites can handle a high volume of visitors. It can handle multiple requests simultaneously, allowing multiple users to access the website at the same time.

The server uses various techniques such as load balancing and caching to optimize website performance. Load balancing distributes incoming traffic across multiple servers, ensuring that no single server becomes overwhelmed. Caching temporarily stores frequently accessed files, reducing the load on the server and improving website speed.

Security and Authentication

Web servers play a crucial role in ensuring the security of websites and protecting sensitive data. They implement security measures such as SSL/TLS encryption to secure the transmission of data between the server and the user’s browser.

The server also manages user authentication, allowing users to create accounts, log in, and access restricted areas of a website. It verifies user credentials and ensures that only authorized users can access certain resources.
