When a user process is interrupted or causes a processor exception, the x86 hardware switches the stack pointer to a kernel stac

k, before saving the current process state. Explain why. Anderson, Thomas. Operating Systems: Principles and Practice (Volume 1 of 4) . Recursive Books. Kindle Edition.

Answer and Explanation

In x86, different stacks are used for kernel & user processes because of security purposes.

The kernel assigns the interrupt dispatch to a common kernel interrupt entry/exit

mechanism which saves pre-interrupt register state before summoning the registered handler(s).

When sending out an interrupt might launch a privilege and/or stack switch,

interrupts that occur while executing user process will switch to use the kernel stack in place at that point, without saving current state.

densk [106]

Answer:

hello your question is incomplete attached below is the complete question

answer : attached below

Explanation:

let ; x(t)  be a real value signal for x ( jw ) = 0 , |w| > 200\pi

g(t) = x ( t ) sin ( 2000 \pi t )

x_{1} (t) = \frac{1}{2}  x(t)  sin ( 4000\pi t )

next we apply Fourier transform

attached below is the remaining part of the solution

How are speed and acceleration related
erica [24]
R = distance

dr/dt speed or with a direction, velocity

d(dr/dt)/dt = the time derivative of the velocity is called acceleration.

Speed is a scalar. Acceleration is a vector.
