Every bit of online data still has to “live” somewhere in the physical world. Email accounts, blog posts, text messages, and the like all need something to store them and make them available to their users upon request. For websites this living space, so to speak, is a hosting server.
Web hosting is the service that maintains your website and provides the rest of the internet with access to it. It takes care of actually storing the data that forms your website, as well as managing traffic coming to and from that site. Hosting servers are the computers that a Web Hosting service uses to do this constant and critical work.
Everyone needs some kind of hosting to get their website out to the digital world. It is technically possible to purchase and use your own device to host your website, but web hosting is a complex, continuous, and resource-demanding process. Dedicated web hosting services already have servers, a properly controlled storage space, and a large amount of bandwidth to ensure your website is safe, well-maintained, and easily accessed by online visitors.
In short, web hosting is essential to running a modern website. Content on the World Wide Web can’t exist unless it has some physical place to be stored, and the best content is stored on servers that are safe, properly cared for, and provided with high bandwidth to ensure traffic quickly and smoothly flows to and from your website.
