hi all,
i want to difference between following three things.
i)Firmware
ii)Bootloader
iii)Driver.
in my view
Firmware - used to control one particular chip or used to transfer the data from one protocol to other type protocol.
Bootloader - used to allow the downloaded code from particular memory address.
Driver - used to access particular device.
pls help me.
thanks in advance..........
One more to the view:
Firmware
Messed up term, that these days mean anything from programmable logic configuration to any embedded SW.
They even speak of an Android distribution in a smartphone as "the firmware".
Boot loader
As the name says - loads a system to be booted. Usually at least part of the (lowest level) boot loader is PROMed into the system, but sometimes (like in case of JTAG) could be external. Summa summarum: a piece of code that allows loading of a bootable system into a device's core somehow, and booting it there.
Driver
Usually OS-dependent piece of code that knows how to handle a device, like MMU, USB-chip, HDD, ... and that the OS uses for operating that device. Sometimes even bare metal code module that offers a simple interface is called a driver.
