Mainframe is IBM's registered trademark for their operating systems involving the origin of virtually everything on a normal PC. You name it, it was used for mainframe. They are bulky, huge, everything is mammoth size for mainframes. The movies depict truth in this respect only (about size, for eg Charlie's Angels features a really big mainframe with high security). But mainframes although involved in number crunching like monsters, they dont have sportive GUI like windows as they show in movies
Mainframes really rock...hmmmmmmmmm
