A web host and a domain serve two different but crucial roles in the functioning of a website. A domain, or domain name, is the address where internet users can access your website. It's the string of characters you type into a web browser to visit a specific website, such as www.example.com. Domains need to be registered with a domain registrar, and they function somewhat like a phone book for the internet, translating memorable names into IP addresses that computers can understand. A web host is a service provider that stores your website files and makes them accessible to anyone on the internet. When someone types your domain name into their browser, their computer sends a request to your web host's servers to access the files of your website. So, while a domain name serves as your website's address, the web host provides the actual "physical" space (in the form of server storage) where your website lives. You need both a domain and web hosting to have a functioning website, but they are two distinct components that work together to bring your site to the internet.
