Hardware
Hardware is best described as a
device that is physically connected to your computer or something that can be
physically touched. Most hardware will contain a circuit board, ICs, and other electronics. A perfect example of hardware is a
computer monitor, which is an output devicethat lets you see what you're doing on the computer. Without any
hardware, your computerwould not exist, and software would not be able to run.

What are hardware
upgrades?
A hardware upgrade is any new hardware that
replaces or adds to old hardware in the computer. A good example of a common
hardware upgrade is a RAM upgrade, where the user
is increasing the computers total memory, which will increase its overall speed
and efficiency. Another good example is doing a video card upgrade, which is
the act of removing the old video card and replacing it with a new video card
that is much more capable than the previously installed video card, again
increasing the capabilities of the computer.
