"Can you describe the steps involved in initializing a device through its driver when the system boots up? Please provide an example, such as initializing a network card, detailing the processes and configurations involved."
When the system boots up device drivers initialize the hardware with resetting the device, setting default operational parameters and configuring the device to work in tandem with other system components.
e.g. Network driver would initialize the chip loading its firmware and setting configurations for the card for data transmission.
