An operating system support communication between applications through regions of memory shared between the applications. For example, a computer's RAM (random access memory) allows each running application to use a portion of the computer's memory.

• Describe the steps in detail that the operating system performs to handle interrupts, including ISRs, the stack, and hardware?

sdas [7]

Answer:

Operating system is the software that is used to control different hardware of computers and handle scheduled tasks.

It also handles the interrupts from some external devices, or from some software. The interrupts are handled through Interrupt service routine. When some external event occurs the following steps has been taken by OS to perform the operation

In first step, an external event has been occurred, and request to the cpu to perform operation.
This request invoke ISR (Interrupt service routine), to perform the operation.
The interrupts are stored in stack on the priority basis.
The CPU performs the operation on Interrupt as per request of ISR.
After Completing operation, CPU return to its initial task.

We use a cubic equation in which the variables and coefficients all take on values in the set of integers from 0 through p - 1 a

dezoksy [38]

Answer:

We use a cubic equation in which the variables and coefficients all take on values in the set of integers from 0 through p - 1 and in which calculations are performed modulo p for a __Prime Curve_ over Zp.

Explanation:

Two families of elliptic curves are used in cryptographic applications

Binary curves over GF(2m):
Prime Curves over Zp.
