hardware is wat it means
its hard, lol. Hardware is what a PC is made of. All its components inside the case is hardware. Its actual physical objects.
software are programs on the computer, in the hard drive. software is what runs on the computer. Windows is software, and so is all the stuff u install on it.
Good site for building PCs:
(good for searching for parts)
Its best to build the pc urself and not pay people to do it, as u learn more from it.
Any more questions please ask.
PS: input is exactly wat it means, its wats inputed into the computer through different methods so it can output something to the user. input = to computer output = from computer (this applys to the case of a pc, but input/output applys to different technological stuff)
