What is the unlikeness between Firmware and Hardware?
Let us take a look at what ‘Hardware’ means when you talk about computers – approximately all of the devices that you can find assembled into your computer come under the class of hardware. This includes the processor, the memory, the motherboard, the hard disks, the removable media drives (Cd-Rom/Dvd Reader/Writer, floppy drives, Usb drives, the power supply, sound card, networking devices and Input/Output devices.
What makes all these hardware devices work together is the software that controls them. Software is the term given to programs that are ordinarily run on computers. You may be customary with and may have used many software packages – word processing software such as Ms-Word and games are coarse examples. Software ordinarily resides on the hard disk of the computer and is ordinarily invoked by the operating ideas to accomplish definite tasks. It is ordinarily coded in high-level languages like C or Java.

Firmware is a term used for a definite type of software. Many processors (other than the Cpu of your computer) need software to implement a functionality and this ordinarily is programmed into some kind of Read-only Memory (Rom) on the gadget itself. This bundled or embedded software that controls a hardware gadget is called Firmware. Firmware is code that is meant for a singular hardware gadget and is ordinarily in machine code (patterns of zeros and ones).
A good example would be that of surfing the Internet – you would use hardware in the form of a network card or a modem to connect to the Internet. The Operating ideas on your computer communicates with the network card or modem using software called gadget drivers. The processor colse to which the modem or the network card is built colse to would have its own firmware that controls the transportation with the Internet and the host (computer).
Another good example of firmware in operation is a cell phone, a washing machine or a microwave oven. Firmware is not ordinarily meant to be reprogrammable, though in extra cases like a cell phone, it may be so.
If you receive updates from the makers of devices like the Cd-Rom drive in your computer that contribute supplementary functionality or remove bugs, it is probably a firmware update and your Os would use the gadget drivers for that hardware to update the firmware.
