Servers

A web server is software that grants access to websites through HTTP and HTTPS protocols. It operates on the server and accepts requests from clients (e.g., browsers) and responds by sending the requested data.

Web servers are composed of several components:

1. A server application that processes requests and generates responses.

2. A request handling application that analyzes requests and determines which resources should be returned.

3. A database containing information about web pages and other resources.

4. A network interface responsible for managing incoming and outgoing network packets.

Web servers can operate on various operating systems: Windows, Linux, and macOS. Additionally, they can support different programming languages: PHP, Python, Ruby, and Java.

A single server can manage multiple websites using virtual hosts. This means each website has its own domain name and separate file set, but all are served by the same server. (Source: From servercore)
