Functions of Interrupts and system calls
What are the various functions of Interrupts and system calls?
Expert
a. Interrupts allow the CPU to switch back to the kernel mode, as this cannot be done automatically.
b. The CPU consist of many interrupts which can allow certain types of events such as timers, keyboard and output devices to interrupt the CPU.
c. For the events in the form of interrupts that are taking place in the CPU an interrupt handler is being setup to handle it.
d. During the interrupt the CPU stops the working of the currently running program and it switches to the kernel mode.
e. The interrupt handler is being executed to manage the events that are occurring in the system.

Limit the Scope of Data Declarations at the smallest possible level is consistent with the well known principle of data hiding. It stops one module from inadvertently referencing and modifying data values which are only meant to be used by another mod
Heap Abstractions: The class abstractions that we discussed above are obtained by abstracting each field of base type. The number of instances of that particular class still needs to be bounded; this results in an under-approximation that is still use
Out of scope: It is a variable is in scope as long as the program's flow of control is in the variable's defining block. Or else, this is out of scope.
