A television remote control is an example of an engineered product that contains firmware.The firmware monitors the buttons, controls the LEDs, and processes the button presses in order to send the data in a format the receiving device, in this case, a television set, can understand and process.is a type of software that provides control, monitoring and data manipulation of engineered products and systems.Typical examples of devices containing firmware are embedded systems (such as traffic lights, consumer appliances, remote controls and digital watches), computers, computer peripherals, mobile phones, and digital cameras.
Without firmware your camera would not be able to operate.
This may require ROM integrated circuits to be physically replaced, or flash memory to be reprogrammed through 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.
This topic is one that I often find myself explaining in more detail, and one that many people aren’t even aware that they can update their camera’s firmware, and how this may affect their digital camera.
An analogy is to updating the version of software on your smart phone.
