Definitions for firmwareˈfɜrmˌwɛər
This page provides all possible meanings and translations of the word firmware
(computer science) coded instructions that are stored permanently in read-only memory
Something in-between hardware and software. Like software, it is created from source code, but it is closely tied to the hardware it runs on.
Software for embedded computers.
In electronic systems and computing, firmware is the combination of persistent memory and program code and data stored in it. Typical examples of devices containing firmware are embedded systems, computers, computer peripherals, mobile phones, and digital cameras. The firmware contained in these devices provides the control program for the device. Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory. Changing the firmware of a device may rarely or never be done during its economic lifetime; some firmware memory devices are permanently installed and cannot be changed after manufacture. Common reasons for updating firmware include fixing bugs or adding features to the device. This may require physically changing ROM integrated circuits, or reprogramming flash memory with a special procedure. Firmware such as the ROM BIOS of a personal computer may contain only elementary basic functions of a device and may only provide services to higher-level software. Firmware such as the program of an embedded system may be the only program that will run on the system and provide all of its functions.
The New Hacker's Dictionary
Embedded software contained in EPROM or flash memory. It isn't quite hardware, but at least doesn't have to be loaded from a disk like regular software. Hacker usage differs from straight techspeak in that hackers don't normally apply it to stuff that you can't possibly get at, such as the program that runs a pocket calculator. Instead, it implies that the firmware could be changed, even if doing so would mean opening a box and plugging in a new chip. A computer's BIOS is the classic example, although nowadays there is firmware in disk controllers, modems, video cards and even CD-ROM drives.
