Answer:
Mainframe Computer System 
Explanation:
Mainframe systems or simply mainframes are computers used for critical application, bulk processing and transaction processing. 
They are larger than the basic computers we find around. They are advantageous as they are able to process large data faster. For this reason, large institutions like banks tend to use them for processing of data because of the thousands of transactions they engage in.
They are capable of handling and processing very large amount of data quickly. 
Examples of other large institutions that uses mainframe computers apart from Bank stated in the question are
1. Stock brokerage firms
2. Government agencies 
3. Insurance agencies
4. Fortune 500 companies and so on.
 
        
                    
             
        
        
        
Answer:
by using forms
Explanation:
Most of the database users perform the data searches by using the forms. A form can be used to enter, edit and display the data from the data source. Its a user interface in fact that fetches the data from the database. Reports have used the display the data for a certain type of user, and the viewing table does not look feasible to search from a very large database, and the databases are usually large. No calculation is required for searching the data, and we only need to write queries in the right syntax. Hence, here the correct option is by using forms. 
 
        
             
        
        
        
Answer:
a=4 , b=1
Explanation:
I'm not a computer science major at all but I think I can help you with this code.
Our program wants us to add 2 to a get new a value while also subtracting 1 from b value to obtain new b value. We we want to for for as long b is not 0 and a/b is nonnegative.
One round we get:
New a=0+2=2
New b=3-1=2
Let's see if we can go another round:
New a=2+2=4
New b=2-1=1
We can't go another round because b would be negative while a is positive which would make a/b negative. So our loop stops at this 2nd round.
a=4 , b=1
Other notes:
2nd choice makes no sense because a is always going to increase because of the addition on a and b was going to decrease because of the subtraction on it.
Third choice makes no sense because a/b doesn't even exist.
Fourth choice a/b is negative not nonnegative.
