Is an operating system call an interrupt?
So I know an operating system call is a demand to the OS to receive some type of resource. What i don't know is whether or not the operating system call is an interrupt or not? Or are all operating system calls interrupts? I know a device interrupts the OS for a resource, but are operating system calls just instructions from a program and not an interrupt? Or is an interrupt just a special instruction?

In an operating system, what is the difference between a system call and an interrupt? Are all system calls interrupts? Are all interrupts system calls?

I'm confused with system calls.
The question is: Is there a system call service routine, which is always called, in order to find a specific system call, like write, read, etc. ?

since we know that operating system works in protected mode
and BIOS works in a Real mode ( 16 bit). so when an interrupt is called from
either Operating System or application program, does CPU swi...

We may place operating system in either low memory or high memory. The major factor affecting this decision is the location of interrupt vector. Since the interrupt vector is usuall...

Per my understanding, a system call is serviced when a software interrupt is triggered, so I think it can't interrupt a hardware ISR because local CPU irq is disabled inside ISR, but it looks possi...

System calls are implemented using software interrupts(interrupt vector 128). In roberts love book "Linux Kernel Development" its written that interrupt handle happens at interrupt context. Its also

I saw in an article that the operating system is interrupt-driven. Is the operating system interrupt-driven or event-driven?
Thank you.

This question may seem slightly vague, however I am researching upon how interrupt systems work and their latency times. I am trying to achieve an understanding of how architecture facilities such ...
