Yes. You can register domain names before you find a hosting provider, and, in fact, you are not required to host a domain name.

When you register a domain name with us, we automatically park it. A temporary, parked page displays when visitors type the domain name into their browser's address bar. The parked page indicates you are reserving the site.

A Domain name transfer is the process of changing the designated registrar of a domain name. ICANN has defined a Policy on Transfer of Registrations between Registrars[1] The usual process of a domain name transfer is:

A virtual private server (VPS) is a physical server that has been divided (using software) into several virtual machines, each acting as an independent dedicated server. The physical resources such as RAM, CPU and disk space are still shared, but each VPS acts independently of the others. Each VPS can have a different operating system and can be configured in any way possible.

Shared hosting allows thousands of people to host their own sites at a very reasonable cost. It has some drawbacks, however. Since hundreds of sites can be hosted on a single server resources such as CPU, disk space, and bandwidth have to be shared with your virtual neighbours.
