There are 2 services that you’ll need for a working website - a domain and a website hosting plan for it. Each time you type the domain address in your Internet browser, you see the content that is uploaded inside the website hosting account, but if that Internet domain is not linked to such an account or to an email service, it is parked. In other words, the domain name is registered and you are its owner, but it lacks content of its own. Instead, it can open either a pre-made “Under Construction / For Sale” page from the registrar company, or it could be forwarded to any other URL of your choice. The main benefit of parking a domain is that you can keep it and ensure that no one else will take it. In the meantime, it's not going to block a slot for a hosted domain address within your account. You may also park domain names if you have a .com, for example, and you register domain names with other extensions such as .net, .org or country-code ones to direct them to the main website in order to protect a brand name.
