Understanding Web Servers and Types of Web Servers

A web server is a software application or hardware device responsible for serving content to clients over the internet or an intranet. It plays a crucial role in the infrastructure of the World Wide Web, facilitating the exchange of information between web servers and client devices, such as computers, smartphones, and tablets. Web servers process incoming requests from clients, retrieve and deliver web pages, files, and other resources, and communicate with other servers to fulfill user requests. They utilize protocols like HTTP (Hypertext Transfer Protocol) and HTTPS (HTTP Secure) to transmit data securely over the internet. Web servers come in various forms, including open-source software like Apache and Nginx, commercial solutions like Microsoft Internet Information Services (IIS), and cloud-based services offered by providers like Amazon Web Services (AWS) and Google Cloud Platform (GCP). In essence, web servers form the backbone of the internet, enabling the seamless delivery of web content to users worldwide
