Each server is a little different. On some servers you can have aliases. Before copying your files over give some thought to the file structure you want to have. Besides the file structure decide on any additional services you will need on the server. Many like having an FTP server because it allows them to remotely post new pages and make files available for downloading.
Many servers have administration utilities that are web based and allow off-site administration.
Once you know what kind of a computer will be your web server and the services you will need you can start looking for a web server. Believe it or not, there are many free or inexpensive web servers available for download on the web. There are also many great commercial servers. Unless you are planning to host a large site, I suggest you try one of the free ones. This server may be the one you want.
