What are servers that provide content over the internet commonly called?

The term "web hosts" refers to servers or service providers that store and serve websites and web applications to users over the internet. They are responsible for making the content of these sites accessible via browsers and other internet-enabled devices. Web hosts provide the infrastructure, including servers and storage, necessary for hosting websites and ensuring they are available for access at any time.

Content Delivery Networks, while related, focus on the distribution of content across multiple servers to improve access speed and reliability, rather than solely providing hosting services. Domain servers are responsible for translating domain names into IP addresses, facilitating traffic flow on the internet, but they do not host content themselves. Data centers refer to the physical facilities that house the servers and storage equipment, which may host many different services, not solely web hosting. Therefore, web hosts specifically cater to serving and maintaining web content, making them the correct answer in this context.
