Generally there are two types of hosting.

Unix and windows. A unix host will typically support PHP and MySQL only, whereas, a windows host will support ASP and SQL Server.

It is uncommon for a single account to support both. Most good hosting companies will provide both types of hosting.

I must point out that although it is not impossible to support both styles on the same server, it is not usually the case.

If you reply stating where abouts in the world you are we can probably point out some hosting companies for you.
