Webservers

A web server is a computer system paired with software that stores and serves web content, making it accessible to users online. Its main job is to store, process, and deliver web pages, making website content accessible to users. Web servers offer advantages like easy scalability and the ability to serve multiple users simultaneously, which makes them essential for modern websites. However, they can also face disadvantages such as security vulnerabilities and the need for regular maintenance to ensure optimal performance. 

There are four main types of web servers such as Apache, IIS, Nginx, and LiteSpeed. Apache is a free, open-source server known for its ability to deliver web content efficiently. It works well on both Linux and Microsoft Windows systems. Conversely, IIS is Microsoft's web server that runs exclusively on Windows. It supports various protocols, including HTTP, HTTPS, and FTP, making it a robust choice for exchanging web content. Nginx is another open-source server famous for its high performance and low resource consumption. Many developers use it for tasks like load balancing, reverse proxying, and caching due to its versatility and speed.  Finally, LiteSpeed is a proprietary web server developed by LiteSpeed Technologies. It currently holds the title of the fourth most popular web server, powering around 13.9% of websites. Each of these web servers has unique features that make them suitable for different applications and needs.
