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 Logitechwebcam, an example of an external hardware peripheral. This hardware device allows users to take videos or pictures and transmit them over the Internet.

SOFTWARE
Sometimes
abbreviated as SW and S/W, software is a collection of instructions
that enable the user to interact with a computer, its hardware, or
perform tasks. Without software, computers would be useless. For
example, without your Internet browser, you could not surf the Internet
or read this page and without an operating system, the browser could not
run on your computer. The picture to the right is a Microsoft Excel
software box and an example of a spreadsheet software program.
