There are many ways to forward site visitors from one domain/website to another. The so-called URL redirection is frequently favored. In contrast to parking a domain address, a URL forwarding is possible only if the domain in question is hosted. What this means basically is that you can still open any content if you have a direct link to it and you can set up email addresses or subdomains and use them. This sort of feature has many practical uses - if you decide to switch your domain name, you could forward the site visitors, but the e-mail messages with the old one shall still be active if you are making contact with customers or partners. If you have 2 very similar websites and you intend to rebuild one of them, you can forward the visitors to the other website to prevent losing potential clients, while you'll still be able to access the administration area for the first website and improve it.
