In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband

transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.

ll the above listed methods are used in storing sequential files

#include<stdio.h>
int main(){

  int s,temp,i,j,a[20];

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

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

  //Bubble sorting algorithm
  for(i=s-2;i>=0;i--){
      for(j=0;j<=i;j++){
           if(a[j]>a[j+1]){
               temp=a[j];
              a[j]=a[j+1];
              a[j+1]=temp;
           }
      }
  }

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

  return 0;
}

Insert image into a table

Create the following table:

      create table pics_table (

      bfile_id number,

      bfile_desc varchar2(30),

      bfile_loc bfile,

      bfile_type varchar2(4))

      TABLESPACE appl_data

      storage (initial 1m next 1m pctincrease 0) 

Insert Query:

      INSERT INTO pics_table

      VALUES(4,'test image',bfilename('GIF_FILES','Test.JPG'),'JPEG');
