A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web.
When Internet users want to view your website, all they need to do is type your website address or domain into their browser. Their computer will then connect to your server and your webpages will be delivered to them through the browser.
Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation.
Most hosting companies require that you own your domain in order to host with them. If you do not have a domain, the hosting companies will help you purchase one.
If you decide to create and host your website, you can get a custom domain, email addresses, and web hosting all bundled into one subscription.
