A device driver is software that allows the operating system to communicate with hardware devices. While drivers can be stored in firmware, they are often installed on the operating system itself and can be updated independently. Firmware typically refers to low-level software programmed into hardware components, while device drivers serve as a bridge between the OS and the hardware. Therefore, not all device drivers are embedded in firmware, but some can be part of it.

Difference between lineware and firmware in computer?
Firmware refers to the software that is embedded within a hardware device. Lineware on the other hand refers to a company that deals with software development.
Is keyboard alone an embedded system?
A keyboard alone is not considered an embedded system; it is typically a peripheral device that requires a host system, such as a computer, to function. An embedded system is defined as a dedicated computer system designed to perform specific tasks within a larger mechanical or electrical system, often with real-time computing constraints. While a keyboard contains microcontrollers and firmware, it lacks the autonomy and dedicated functionality characteristic of embedded systems.
What is a very small computer inside a device?
Embedded computer.
Where is firmware stored?
Firmware is typically stored in non-volatile memory, such as ROM (Read-Only Memory), flash memory, or EEPROM (Electrically Erasable Programmable Read-Only Memory). This type of memory retains its contents even when the device is powered off, allowing the firmware to be accessed and executed during the device's boot process. In embedded systems, firmware can also be found on dedicated chips or integrated circuits within the hardware.
Which is the programme inside Rom?
The program inside a ROM (Read-Only Memory) is typically firmware, which is a specific type of software that provides low-level control for a device's hardware. This firmware is embedded within the ROM chip and is not meant to be modified or rewritten during regular operation. It enables the device to boot up and perform its fundamental functions. Examples include the BIOS in computers or the operating system in embedded systems.
What device provides the boot firmware to start the processor?
The device that provides the boot firmware to start the processor is typically the motherboard's Read-Only Memory (ROM), specifically the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface). This firmware initializes hardware components and loads the operating system into memory when the computer is powered on. The BIOS/UEFI is essential for the boot process, as it prepares the system for operation by conducting hardware checks and locating the bootable device.
What electronics run software?
The software is either embedded in a device, such as a hand-held device or appliance, or installed on a computer.
How can you connect embedded Ethernet to device?
To connect embedded Ethernet to a device, you typically use an Ethernet controller or module that interfaces with the device's microcontroller via protocols like SPI or UART. First, ensure the microcontroller has the necessary GPIO pins for the Ethernet module. Then, configure the Ethernet settings (IP address, subnet mask, etc.) in the device's firmware. Finally, establish a physical connection using an Ethernet cable to connect the module to a network switch or router.
What is an operating system that works on a desktop computer and a notebook computer or a mobile computing device?
embedded operating system
What is embedded device?
It is used commonly in todays society A embedded device is a electronic computer that has input, output and process. It sometimes also has storage. Examples are ABS, Washing machines and Mobile phones.
Is firmware software on a non-volatile chip?
Yes, firmware is a type of software that is specifically designed to be embedded in non-volatile memory chips, such as flash memory or ROM. This allows it to retain its functionality and settings even when the device is powered off. Firmware provides low-level control for a device's specific hardware, often serving as the interface between the hardware and higher-level software.
How does the printer communicate with the CPU?
What is often called a printer is simply an output device. The computer communicates with the firmware called printer drivers in the computer. The driver makes the connection with the printing output device.
