Origins and Meanings
Software: The term "software" was coined to contrast with "hardware." It refers to programs and data that are not physical objects but are essential for operating a computer. "Soft" in this context indicates the malleable, changeable nature of software. Software can be easily modified, updated, or deleted without physical alteration of the hardware.
Firmware: The term "firmware" was introduced to describe a type of software that is closely tied to hardware but not as flexible or easily changed as regular software. "Firm" suggests that while firmware is not as rigid and unchangeable as hardware, it is more fixed and less frequently altered than typical software. Firmware is stored in non-volatile memory (like ROM or flash memory) and provides essential control functions for hardware.
Metaphorical Use of Terms
"Firm" in Firmware: Indicates that the software is somewhat permanent, providing a stable and consistent interface between hardware and higher-level software. It can be updated, but the process is less frequent and more controlled.
"Soft" in Software: Emphasizes the flexibility and changeability of the programs. Software can be developed, distributed, and modified rapidly, reflecting its adaptable nature.
Characteristics Reflected in Terms
Hardware: Physical components of a computer system Example: CPU, memory, motherboard.
Firmware: Low-level software embedded in hardware. Example: BIOS or UEFI in computers, microcontroller code in devices.
Software: High-level programs and applications. Example: Operating systems, word processors, games.
Summary
Hardware: Physical, tangible components of a device.
Firmware: Embedded software that is relatively fixed but can be updated; essential for hardware control.
Software: Flexible, easily modified programs and applications running on a device.
Conclusion
The use of "firm" in firmware and "soft" in software serves as a metaphorical way to describe their characteristics and relationship with hardware. Firmware is "firm" because it provides a stable, less frequently changed control layer for hardware, while software is "soft" due to its adaptable and changeable nature. This metaphor helps convey the different roles and properties of these components within a computing system.
