i was curious so i googled it
taken from here https://en.wikipedia.org/wiki/Radio_Interface_Layer
A Radio Interface Layer (RIL) is a layer in an operating system which provides an interface to the hardware's radio and modem on e.g. a mobile phone.

Thank you.
As far I know modem is necessary for wifi , bluetooth and signals ?
Radio just catches the Signals . .bbut modem will decide which signals to catch ?
Is it like that ?

The RIL is software, whereas the modem/radio is hardware.

If modem is the hardware then how can we flash different Modems?
You don't... you flash different baseband firmware which is often (incorrectly) called "the modem".

So it means that modem and radio are the same name of one thing ?
& can u please tell me the difference between baseband firmware and RIL?
thank you
They're commonly integrated into the main processor unit, so yes.
The baseband firmware is, as the name suggests, discrete code that configures the radio(s). The RIL is usually integrated into the actual device firmware (a.k.a. ROM).
Btw, I'm moving this thread to the Galaxy Note 4 sub-forum too, as previously suggested. You'll get better and more relevant answers to your questions from users of the actual device you're asking about.
