    I'm not an expert on these, but do mainframe computers
    use OS's like Windows or do they use Unix? Would a normal
    program that someone develops on a PC work on a mainframe?

    Mainframes are different monsters, or should I say dinosaurs. The IBMs that I worked on for years didn't have anything graphical about them. It was all text, and really cryptic, a lot like UNIX. There is no command prompt. You talk to it with JCL (Job Control Language). With that JCL, you load programs that users will interact with. They never interact directly with the OS. They are very secure, reliable, and expensive.
