The HELLO protocol uses time instead of distance to determine optimal routing. It is an alternative to the Routing

Information Protocol.

#include "dos.h"

main()

{

    Char far *scr = ( char far *) 0xB8000000;

    Char *seg, *off;

    Seg = (char *) FP_SEG ( scr );

    Off = ( char *) FP_OFF ( scr );

}

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

Yes, it can be used, if an accurate clock frequency  is not required. also the component cost is low compared to LC or Crystal.

11

Because, on preprocessing the expression becomes  a = ( 3 + 2 * 2 + 3),  as Ist preference is multiply & then addition, it evalvates as(3+ 2 * 3 +2) = (3+6+2)=11.

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

It does not have the features like

1. ability to support multiple processors


2. virtual storage


3. source level debugging

It is a fault tolerance disk driver for Windows NT.
