What is Web Hosting?
Web hosting is a service that provides server space, computing resources, and internet connectivity for websites to be accessible online. When someone visits your domain, their browser connects to the hosting server, which delivers your website's files. Hosting is the foundation that makes websites accessible 24/7 from anywhere in the world.How Web Hosting Works
