Signal is a form of Inter process communication between in a multiprocessing environment. Interrupts are of two types- Software and Hardware. Both these forms stops what the CPU is currently doing and executes the interrupt service routine (handler).

example of Hardware interrupt : Trap, Interrupt from an I/O device.
Software Interrupt : System call, exception etc.

Hope this helps,
