Technical Questions

Distributed systems work in a network. They can share the network resources,communicate with each other.

It is the transfer of sufficient amount of the state of process from one machine to the target machine.

In microprocessor more op-codes, few bit handling instrucitons. But in Microcontroller. fewer op-codes, more bit handling Instruction, and also it is defined as a device that includes micro processor, memory, & input / output signal lines on a single chip.

the basic architectual difference is that microcontroller has an programmable memory while it is not the case with mivroprocessors.

Prefix Notation:

^ - * +ABC - DE + FG

TRUTH TABLE FOR HALF ADDER

A    B  SUM  CARRY

0    0    0         0

0    1    1         0

1    0    1         0

1    1    0         1

INPLEMENTATION:

For SUM, The two inputs A and B are given to XOR gate.

For Carry, The two inputs A and B are given to AND gate.

Hardware device that maps virtual to physical address. In MMU scheme, the value in the relocation register is added to every address generated by a user process at the time it is sent to memory.

->The user program deals with logical addresses; it never sees the real physical addresses

include<stdio.h>
int main(){

  int s,i,j,temp,a[20];

  printf("Enter total elements: ");
  scanf("%d",&s);

  printf("Enter %d elements: ",s);
  for(i=0;i<s;i++)
      scanf("%d",&a[i]);

  for(i=0;i<s;i++){
      for(j=i+1;j<s;j++){
           if(a[i]>a[j]){
               temp=a[i];
              a[i]=a[j];
              a[j]=temp;
           }
      }
  }

  printf("After sorting is: ");
  for(i=0;i<s;i++)
      printf(" %d",a[i]);

  return 0;
}

Output:
Enter total elements: 5
Enter 5 elements: 4 5 0 21 7
The array after sorting is:  0 4 5 7 21

An interrupt that can be turned off by the programmer is known as Maskable interrupt.
