i want to difference between following three things.
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..........
I moved your question to Embedded.
Here are how I would personally describe them:
How does that sound?
One more to the view:
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".
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.
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.
A few electric appliances normally use embedded software, while some others rely on firmware. I would recomend to see the detailed comparison of both with real-life examples here https://www.reviewsed.com/firmware-vs-embedded-software/
