A domain name is the address people type to find you. Hosting is the service that stores and serves the website. The website is the content and software visitors use.
These may be supplied by different companies and may renew separately. Website hosting does not automatically mean domain registration, email hosting, backups, or ongoing website changes are included. Check your proposal or service agreement for your specific coverage. If you are unsure who manages each part, share your domain and provider names with RJGA, without sending passwords.
