It fetches the firmware instructions from firmware memory and carries them out. (Nowadays it is common for even small systems to have multiple CPU's for parallel execution, by the way; so up vote 7 down vote favorite 2 I have heard from people working in firmware domain, that there is no Operating system controlling firmware (eg firmware in a USB drive). It might come on an integrated circuit chip, so that updating a device to new firmware might involve removing an integrated circuit ("EPROM chip") from a socket and plugging in a Because it is in such memory, firmware is available when the machine is turned on.

Firmware hacks usually take advantage of the firmware update facility on many devices to install or run themselves. However, if the installed system runs a different kernel version from the installer there is a slight chance that the firmware cannot be loaded due to version skew.

Firmware Update Lg Firmware is just software in a fixed form, used to be in a plain (write-once or even mask-programmed) ROM, now mostly in flash (re-writeable) ROM.
Firmware in embedded systems fills the same purpose as a ROM but can be updated more easily for better adaptability to conditions or interconnecting with additional equipment. As originally used, firmware contrasted with hardware (the CPU itself) and software (normal instructions executing on a CPU). Contrast this to a PC which is expected to be very flexible and be able to run all kinds of applications at once. The word "operating system" simply refers to a control program which has a certain degree of sophistication and completeness in managing the resources of the machine and providing reasonably high level
