Firmware Software
These are the operational software installed on the computer motherboards that help the operating system to identify the Flash, ROM, EPROM, EEPROM, and memory chips.
However, the primary function of any firmware software is to manage and control all activities of individual devices. Initially, it uses non-volatile chips for installation purposes, but later it gets installed on the flash chips.
There are two main types of chips:
- BIOS (Basic Input/Output System) chip.
- UEFI (Unified Extended Firmware Interface) chips.
The BIOS (Basic Input/Output System) also works as a system program used for the booting process of the system. First, it loads the OS into the main memory (RAM) of your system and then hands it over to the OS. BIOS works as the substitute for the ROM chip; hence, it is called firmware software. However, the firmware ROM is part of every motherboard component. The motherboard firmware activates all the hardware components during the start of the computer system and ensures whether they are operational or not. If they work properly, it starts the booting process to load the OS, and if any error occurs in the RAM, then it denies the computer to boost.
A Firmware exists inside the devices while a device driver is installed in the operating system.
