According to TechTerms.com, web pages are stored in web servers. A web server can refer to either the physical hardware — a computer system that runs special software designed to handle Internet traffic — or the software itself.
A web server's primary use is to deliver web pages to any electronic device capable of interfacing with the web server, which means that the particular device must be connected to the Internet and have the appropriate software installed. Web pages compose websites. Web servers are most commonly used to host websites, but their uses also include hosting email services, database storage, online gaming and almost anything related to the Internet.
