The web server

 

The web server is a computer that stores and delivers web pages to users. It is connected to the internet and has a web address, such as www.example.com.

When a user requests a web page, the web server sends the requested page back to the user's computer. The web page is made up of HTML code, which tells the user's computer how to display the page. The web page may also contain images, videos, and other content.

The web server also handles requests for dynamic content. Dynamic content is content that is generated on the fly, such as the results of a search query. The web server uses a programming language, such as PHP or Python, to generate the dynamic content.

The web server is an important part of the internet. It allows users to access and view information from all over the world.

Here are some of the components of a web server:

• Hardware: The hardware of a web server typically includes a computer, a hard drive, and a network connection. The computer must be powerful enough to handle the load of requests from users. The hard drive must be large enough to store the web pages and other content. The network connection must be fast enough to deliver the content to users.
• Software: The software of a web server includes the operating system, the web server software, and other supporting software. The operating system is responsible for managing the hardware resources of the computer. The web server software is responsible for receiving and responding to requests from users. The supporting software includes software for managing security, logging, and other tasks.
• Configuration: The configuration of a web server is the set of settings that control how the web server operates. The configuration settings include the port number that the web server listens on, the location of the web pages, and the security settings.
