software

The terms software and hardware are used as both nouns and adjectives. For example, you can say: "The problem lies in the software," meaning that there is a problem with the  progrm or data, not with the computer itself. You can also say: "It's a software problem."
The distinction between software and hardware is sometimes confusing because they are so integrally linked. Clearly, when you purchase a program, you are buying software. But to buy the software, you need to buy the  disk (hardware) on which the software is recorded.

The operating system is the most important type of system software in a computer system. Without an operating system, a user cannot run an application program on their computer, unless the application program is self booting.

hardware

Refers to objects that you can actually touch, like printer, keyboard, mouse, disk, drive, disk, boards, and chipes. In contrast, software is untouchable. Software exists as ideas, concepts, and symbols, but it has no substance.

A computer without software is like a book full of blank pages -- you need software to make the computer useful just as you need words to make a book meaningful.
