A domain and web hosting are different parts of the same website setup. The domain is the address people use to reach you. Hosting is the service that stores and serves the website itself.
What a domain does
Your domain is the human-readable address for your website, such as example.com. It points visitors toward the systems that deliver your website and can also be used for professional email.
What hosting does
Hosting provides the environment where the website’s files, database and software run. You can choose WordPress hosting, cPanel hosting, a website builder or more advanced server options.
Do you need both?
Most business websites need both a domain and either hosting or a hosted website-builder product. Buying a domain alone does not create a website.
Where business email fits
Professional email is another separate service. It lets you use an address such as [email protected]. Compare current business email options if you need domain-based email.
Start by checking domain availability, then choose the website platform that fits how you want to build.
