Updating transmission ubuntu
Originally, it meant the contents of a writable control store (a small specialized high speed memory), containing microcode that defined and implemented the computer's instruction set, and that could be reloaded to specialize or modify the instructions that the central processing unit (CPU) could execute.
As originally used, firmware contrasted with hardware (the CPU itself) and software (normal instructions executing on a CPU).
Common reasons for updating firmware include fixing bugs or adding features to the device.
This may require ROM integrated circuits to be physically replaced, or flash memory to be reprogrammed through a special procedure.
In contrast, firmware in storage devices (harddisks, DVD drives, flash storage) rarely gets updated, even when flash (rather than ROM) storage is used for the firmware; there are no standardized mechanisms for detecting or updating firmware versions.
Most computer peripherals are themselves special-purpose computers.
It was not composed of CPU machine instructions, but of lower-level microcode involved in the implementation of machine instructions.
It existed on the boundary between hardware and software; thus the name "firmware".
In some respects, the various firmware components are as important as the operating system in a working computer.
most portable music players support firmware upgrades.
