Explanation:
Answer:
Option C
Explanation:
All of the following are true about data science and big data except No digital data is stored in traditional databases
Reason -
Data generated in current time is of large size and is also complicated. Traditional data bases such as SQL databases etc. are not capable to store data that is changing at a fast pace and has huge volume, veracity, variety and velocity. But big data platforms such as Hadoop can store big data and process it speedily and easily.
Solution:
Users of an access point share the transmission capacity of the access point. The throughput a user gets is called the bits per seconds.
Thus this is the required answer.
Answer:
1.
class TIME
{
int hour , min , sec ;
public :
TIME()
{
hour=min=sec=0;
}
TIME( int h , int m , int s )
{
hour = h;
min = m;
sec = s;
}
void change ( int Hour)
{
hour = Hour;
}
void stdtime()
{
if(hour>12)
cout<<"The Standard time is"<<(hour-12)<<":"<<min<<":"<<sec<<"P.M\n";
else
cout<<"The Standard time is"<<hour<<":"<<min<<":"<<sec<<"A.M\n";
}
void miltime()
{
cout<<"The Military time is"<<hour<<":"<<min<<":"<<sec<<" hours\n";
}
};
void main()
{
TIME A , B(13,25,30);
A .stdtime();
A.change(23);
A.miltime();
B.stdtime();
B.change(9);
B.miltime();
}
2.
class elevator
{
int CurrentFloor;
int GoingUp;
int GoingDown;
public:

{
CurrentFloor=0;
GoingUp=1;
GoingDown=-1;
}
elevator(int floor)
{
CurrentFloor=floor;
GoingUp=1;
GoingDown=-1;
}
void goUp(int y)
{
if( CurrentFloor>3)
cout<<"\nNO MORE FLOORS\n";
else
CurrentFloor=CurrentFloor+y*GoingUp;
}
void goDown(int x)
{
if(CurrentFloor<0)
cout<<"\nNO MORE FLOORS";
else
CurrentFloor=CurrentFloor+x*GoingDown;
}
};
void main()
{
elevator A(1);
A.goUp(1);
A.goUp(1);
A.goUp(1);
