There are two types of secondary memories.
- RAM
- ROM
RAM:
- RAM stands for random access memory .
- It is expandable.
- we can do multiple things in it.
- Its erasable.
ROM
- ROM stands for read only memory.
- It is permanent .
- We can only read in it.
- Its permanent hence not removable.

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
Answer:
This is the case of redundancy or the repeated data. It means that the same data is being repeated again and again. And its the wastage of time and memory both. The redundancy must be removed in all circumstances. However, we cannot as without it proper normalization of data is not possible.
Explanation:
The answer is self explanatory.
