Now, what are
the definitions of "microcomputer", "minicomputer",
"mainframe"?
If you lose your screwdrive inside it, it's a micro. If you lose your
multimeter inside it, it's a mini. If you lose your 'scope inside it, it's
a mainframe. And if you lose yourself iniside it, it's a supercomputer.
And if has a lose screw - its lap top. :)
