The stuff that makes up your
computer and all it's pieces and parts. Includes things like your
keyboard, your
hard drive, and your
modem. Usually made up of
circut boards and
wires.
An older forgotten meaning refers to things like
hammers,
2x4's, and
power tools as hardware. This is the stuff
men buy in the
Sears Craftsman department so that they can go home and fix things, build things, or break things they were trying to fix.
