What is the difference between drivers and firmware

A typical computer consists of hardware, software and firmware. Hardware is any physical device that you can actually see and touch, whether internal to the computer or external devices attached to the computer. We use numerous hardware devices with a computer, such as printer, scanner, mice, keyboard, monitor, disk drive, audio card, video card, and modem are all examples of hardware devices.

Software is a set of instructions that tell the computer how to work and execute specific tasks. Device drivers are also software. Firmware is also software, but programmed on a hardware device. Device driver is a particular type of software program that enable hardware devices to interact with each other.

It is a software application that acts as an intermediary between a piece of hardware and an application or the operating system. A computer operates a great many kinds of devices, most of which fit into the general category of storage devices, transmission devices, and human-interface devices. A device communicates with a computer system through its associated device driver.

So, a device driver communicates with the hardware device via a connection point, or port — for example, a serial port. Device drivers are specific to operating system which allow the kernel of the OS to communicate with hardware devices, without worrying about the details of how they actually work.

Firmware is a set of instructions programmed into a hardware device, typically in non-volatile memory such as read-only memory or flash memory. Firmware is a special form of software that enables a device to perform functions without the need of installing additional software. It refers to computer programs and data loaded into a class of memory that cannot be dynamically modified by the computer during processing.

Reason you need to keep the power on during firmware updates Before updating the firmware, you need to download it, verify the integrity of the data, reboot the device and go into boot mode to read more about boot mode and bootloaders refer to this article , then rewrite the flash memory and reboot it again in normal mode.

How Device Drivers Differ from Firmware? Lets us also have another look at the layer diagram before we end this article! And with that I will stop this article!

But they need core knowledge on processors and the latest RAMs, PCIe standards, and so on to write firmware that complies with the latest standards. Device driver engineers need knowledge about the specific device that they are using, the communication standard the device uses to talk to the computer like Bluetooth, USB, etc , and the operating system the device driver is written for.

The kernel is the first layer of abstraction in the platform that insulates software from hardware-specific details. A kernel in that context is something from which the rest grows. Kernel is one of the most important part of Operating System. Kernel is closer to the hardware and often performs tasks like memory management and system calls. It does the same job as a BIOS, but with one basic difference: it stores all data about initialization and startup in an. UEFI provides faster boot time.
