Hardware refers to the physical parts of a computer. Like we buy new cassettes for newly released songs or for songs whose cassettes, we do not have, we buy, new software to be run on the same hardware as and when need arises, or funds become available. Except for upgrades (like increasing main memory and hard disk capacities, or adding speakers, modems, etc.) hardware is normally a one- time expense, whereas software is a continuing expense. Same hardware can be loaded with different software to make a computer perform different types of jobs just as different songs can be played using the same cassette player.ģ. Both hardware and software are necessary for a computer to do useful job. Following important points regarding the relationship between hardware and software are brought out by this analogy:ġ. Similarly, to get a job done by a computer, the corresponding software has to be loaded in the hardware first and then executed. To listen to a song, that song has to be recorded on one of the cassettes first, which is then mounted on the cassette player and played. However, the songs recorded on the cassettes are its software. To take an analogy, a cassette player and its cassettes purchased from the market are hardware. Nothing useful can be done with the hardware on its own, and software cannot be utilized without supporting hardware. For a computer to produce useful output its hardware and software must work together.
