COMPAIR BETWEEN SOFTWARE & HARDWARE... Software is a general term used to describe a collection of computer programs, procedures, and documentation that perform some task on a computer system. Practical computer systems divide software systems into three major classes: system software, programming software, and application software, although the distinction is arbitrary and often blurred. Software is an ordered sequence of instructions for changing the state of the computer hardware in a particular sequence. It is usually written in high-level programming languages that are easier and more efficiene for humans to use (closer to natural language) than machine language. High-level languages are compiled or interpreted into machine language object code. Software may also be written in an assembly language, essentially, a mnemonic representation of a machine language using a natural language alphabet. Hardware is best described as a device that is physically connected to the computer or something that can be physically touched. A CD-ROM, monitor, printer, and video card are all examples of computer hardware. Without any hardware your computer would not exist and software would have nothing to run on. It is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware.
