What does it mean to host a domain?
Hosting (also known as website hosting or Web hosting) is the business of housing, serving, and maintaining files for one or more websites. In a sense, you rent space on a computer to hold your website. Your host, the computer where your website files are stored, assigns an address (DNS) for your files to your domain name so that anyone can find your website on the Internet by typing in your domain name.
