What Is Firmware? Firmware Types and Examples –

Leave a Comment / Operating System /

It is a small software program that is permanently stored in a ‘Read-only Memory’ (ROM) chip. ROM chips are Non-Volatile in nature and do not require a power supply to retain or hold data, unlike RAM memory chips, which need continuous power.

Firmware, often referred to as “software for hardware,” is a type of microcode or program embedded into hardware devices to help them operate effectively and ensuring their efficient operation. Devices like cameras, mobile phones, network cards, optical drives, printers, routers, scanners, and television remotes depend on firmware stored within their memory to operate seamlessly.

The CMOS chip is a small piece of hardware that stores essential information, such as date and time, hardware settings, and BIOS (Basic Input Output System) configurations. It uses SRAM (Static RAM) to retain this data even when the computer is turned off. The CMOS chip also has a battery backup to provide the tiny amount of power needed to keep the SRAM alive.

BIOS, or Basic Input/Output System, is a important firmware program stored on a chip embedded in your computer’s motherboard. This program comes pre-installed by the motherboard’s manufacturer and resides within an Erasable Programmable Read Only Memory (EPROM) chip. Within this chip, a set of instructions takes the form of a program. When you ‘power-on’ your computer, the microprocessor hands over control to the BIOS program, which always resides in this chip.

System calls play a vital role in enabling programs to interact with the operating system. They serve as the bridge between user programs and the OS, providing access to OS services through an API. Whether written in assembly language or high-level languages like C or Pascal, system calls are predefined functions directly invoked by the OS when using high-level languages.

A kernel is the most important program of the operating system package. It can be said that it is the boss of the entire operating system. It has control over the entire operating system, everything in it, every functioning system. The kernel does not directly interact with the user. Establishes coordination and communication with other programs, hardware, devices, processors, memory, disk drives, shells, etc. of the operating system. The kernel monitors and controls every event and functioning of the operating system,
