The user needs to complete the entire disk surface first before starting another surface.
Explanation:
When you are using a multiple disk storage system to write the data the disk automatically writes the disk based on the algorithm for better efficiency and availability of the disk space.
hence when you are recording a data on a multiple disk storage system, it is recommended to fill the complete disk surface initially before you start the another surface to record the data.
 
        
             
        
        
        
Answer:
Sorted array will be:-
3 5 5 9
Explanation:
In Selection Sort algorithm it sorts the array by repeatedly finds the minimum in the array form the array that is unsorted and swaps it with the value at the first position.
The unsorted array:- 5 3 9 5
In first iteration 
minimum is 3.
3 will be swapped with 5.
Now the array is 3 5 9 5
sorted array 3
In second iteration
unsorted array is 5 9 5
sorted array 3 5
and the minimum from it is 5
No swapping will occur.
In third iteration
unsorted array is 9 5
minimum is 5
sorted array 3 5 5
swap it with 9.
Now the array is sorted.
 3 5 5 9

Security systems are detrimental to usability and can make IT systems less functional, and therefore less attractive to the customer.
There is pressure to reduce the time it takes to get a new IT product or system onto the market, so security systems are sacrificed in order to reduce the time-to-market.
Explanation:
