difference between signal and interrupts:
1. signals are asynchronous messages whereas interrupts are
synchronous(in software) and asynchronous(in computing).
2. signals are sent by kernal and handled by user mode program whereas
hardware and software interrupts are sent by hardware and
instructions in instruction set respectively and handled by kernal.
3. signal is a part of inter process communication (ipc) and interrupts
perform context switch to an interrupt handler.
generally signals and interrupts are alike and works on same logic or literally we can say that signal is a kind of interrupt.further synchronous interrupts are called exceptions.
reply me if u have some other differences ...... or any doubts...

Difference between interrupt and subroutine in computer?
interrupt is a signal caused by I/O devices where as subroutine is a part of the program which is excuted rapidly
What is the difference between software and hardware interrupt?
The difference is that a hardware interrupt is a signal relayed to a system's CPU directly because of some piece of hardware, such as a keyboard or mouse. A software interrupt is a signal sent to indicate that something within a piece of software requires attention.
What is the difference between polling and vector interrupt service routine?
polling interrupt is alternative to the vector interrupt , it requires that the interrupt handler poll or send a signal to each device in turn in order to find out which one is sent the interrupt request.....
What is the difference between polling and vectored interrupt system with example?
i need compare between vectored interrupt system and polling
What is the difference between polling and vector interrupt system?
In a computer, a vectored interrupt is an I/O interrupt that tells the part of the computer that handles I/O interrupts at the hardware level that a request for attention from an I/O device has been received and also identifies the device that sent the request. A vectored interrupt is an alternative to a polled interrupt , which requires that the interrupt handler poll or send a signal to each device in turn in order to find out which one sent the interrupt request.
Difference between internal and external interrupt?
internal interrupt is synchronous with the program while external interrupts are asynchronous.
What is difference between vga and lcd display?
The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.
What is the difference between signal processing and signal conditioning?
processing is nothing
Is there a minimum pulse width required for the interrupt signal?
no
What is the difference between signal and wave?
wave is a part of a signal . millions of wave construct a signal .
What is the difference between the modulating signal and the demodulating signal in output of the detector?
Distortion.
What is the exact difference between interrupt handling and exception handling?
interrupt handling is the process of handling a break or interrupt called by a program where as exception handling is for handling some exceptional conditions that'll occur when a program is running
