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
