Explanation:
RAID is a data storage technology that is used to store the data virtually. It keeps a copy of all data so that the data can be recover when it lost from the physical storage. Generally, logical storage is also physical for the computer system. It means that the disk is divided into two parts some parts of the system are physical and some are logical.
The question asked about the technology which solves the problem of interrupting the service. The technology can be RAID as described above . hence Option b is the correct answer while other is not because--
- Option 'a' states about RFID technology which use in an electromagnetic field.
- Option c states about WPA which is a protection mechanism.
- Option d states about OnTrack which is not a technology.

Explanation:
#include <iostream>
using namespace std;
int costdays(int);
int costhrs(int,int);
int main()
{
int dd,hh,mm,tmph,tmpd,tmpm=0;
int pcost,mcost=0;
cout<<"Enter Parking time" << endl;
cout<<"Hours: ";
cin>>hh;
cout<<"Minutes: ";
cin>>mm;
if (mm>60)
{
tmph=mm/60;
hh+=tmph;
mm-=(tmph*60);
}
if (hh>24)
{

}
if ((hh>4)&&(mm>0))
{

}
else

}
cout<<"Total time: ";
if (dd>0)
{

cout<<"Total Cost :"<<pcost<<"Won";
return 0;
}
int costdays(int dd)
{
return(dd*25000);
}
int costhrs(int hh,int mm)
{
int tmpm, tmp=0;
tmp=(hh*6)*1000;
tmp+=(mm/10)*1000;

if (tmpm>0)
{

}
