OK I must admit I am not savvy at all computer aspects, so here is my question -- I would like to try one of the hosting offers but not sure exactly what that is and how it will affect my hard drive space on my computer - I have so much downloaded on my computer now that I don't want to do anything to bog sown my comp. Can someone help me?
A hosting site is a place where you can host a website. It doesn't require you to download anything extra (usually), as the storage is all located elsewhere. Sometimes you can also store your files on it; this would make it a file server.
Having a host should not affect your computer in any way.
