Abbreviated as HW, Hardware is best described as any physical component of a computer system that contains a circuit board, ICs, or other electronics. A perfect example of hardware is the screen on which you are viewing this page. Whether it be a computer monitor, tablet or smartphone; it's hardware.
Without any hardware, your computer would not exist, and software could not be used. The picture is a Logitech webcam, an example of an external hardware peripheral. This hardware device allows users to take videos or pictures and transmit them over the Internet.

What are hardware upgrades?
A hardware upgrade is any new hardware better than that which it replaced or additional hardware that improves performance. A good example of a common hardware upgrade is a RAM upgrade, where the user increases the computer's total memory. Another good example is a video card upgrade, which is the act of removing an old video card and replacing it with a newer, more powerful model.
