A computer system consists of many parts working together. The physical parts of a
computer, which you can see and touch, are collectively called Hardware. It consists
of all input, output, and storage devices.
The hardware of a computer cannot function on its own. It requires a set of
instructions to perform a specific task. The set of instructions that tell a hardware
device to perform a specific task is called Software. It cannot be seen or touched.
