Explanation:
The Hexa-decimal numbers have base 16 and includes numbers:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F
The given steps are performed to convert a decimal number to hexa-decimal number, here to convert decimal number 35 to hexa-decimal number:
- Divide 35 by 16
- Note the remainder, r which is 3 here and quotient which is 2
- Again divide 2 (quotient) by 16 and note the remainder, r' which is 2 and quotient is 0
- We will stop here as the quotient is now 0. Usually division by 16 is repeated until we get quotient = 0
- Now arrange the remainder in reverse order to get the hexa-decimal number as r'r
- The hexa-decimal number is
Answer:
When a programmer tries to access an item in an array cell whose index is greater than or equal to the array's logical size, this data element or item is garbage. This means that currently, the item is not the part of the program's useful data. Garbage contains objects or data which will not be used by a program running on it. So the value returned could be either of the two:
- Value would be an arbitrary or random number if it is an array of numbers. Arbitrary means that the value is not predefined or specified in advance.
- Value returned would be null if it is an array of objects.

Explanation:
40. External Peripherals of a Computer systems are the following:
-> Keyboard – this is an input device
-> Mouse – This is an input device also
-> Printer – this is an output device
-> Flashdrive – This is a storage device
-> Monitor – this is an output device
-> external hard drive – this is a storage device
Output device are those devices that communicate the results of the data processing to the user
Input device are those device that communicate the results of the data processing to the computer system
Storage device are those device that stores data.
