Computer software, or just software, is any set of machine-readable instructions that directs a computer's processor to perform specific operations. The term is used to contrast with computer hardware, the physical objects that carry out the instructions. Hardware and software require each other; neither has any value without the other. Firmware is software that has been permanently stored in hardware. It thus has qualities of both software and hardware. Software is a general term. It can refer to all computer instructions in general or to any specific set of computer instructions. It is inclusive of both machine instructions and source code. On most computer platforms, software can be grouped into a few broad categories: ⁕System software is the basic software needed for a computer to operate. ⁕Application software is all the software that uses the computer system to perform useful work beyond the operation of the computer itself. LESS
