Computer hardware is as distinguished a discipline as software. It's the physical part of a computer. The term `Hardware' has been derived from the concept that it is not changed frequently, whereas `software' are the ones which are in the process of constant creation, modification and recreation inside a computer. In that sense, it's `soft'. This is something you won't find with hardware. The software operates from within the computer hardware.
