  • 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 th...e 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.
