Explanation / Answer

Question -1 :-

-------------------------------

Convert Decimal Numbers to 8 Bit Binary

(Result of division will be taken to next step for division)

X = Input Decimal Value

while(X > 1)

{

nthBit = X%2;

  print nthBit

X = X/2

}

}

95 wll be represented by Binary as 01011111

241 wll be represented by Binary as 11110001

Question -2:-

-------------------------------

Convert Biary to DEcimal

Use below formula

Decimal value += (2n  * nth bit )

where n is index of bits (n == 0...7)

   nth bit is either 1/0

11110011 ______243______________

10010101 _____________149

Question -3:-

-------------------------------

Represent Binary in Hexa decimal values

Hexa Decimal digits are 15 ( 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F)

Calculate decimal value for each 4 bit set (It will be a value between 0 to 15)

Represent the Decimal value in Hex

( if it is 0...9 use same , if greater than 9 use 10 ->A , 11->B , 12->C, 13->D,14 -> E, 15->F)

0101.1101.0111.1001 5.D.7.9

1111.0110.1000.1011   F.6.8.B

Question -4:-

-------------------------------

Convert IP Address to Binary

Conver Each IPV4 value (seperated by . into Binary )

152.75.109.81 10011000.01001011.01101101.01010001

65.98.225.248 01000001.01100010.11100001.11111000

Question -5:-

-------------------------------

Compressed IPV6 is represented in Hexa Decimal format and remove leading 0's

for example 00FF represented by FF

000F represented by F

FE80:F1:5C1:BA::6D  -------> FE80:00F1:05C1:00BA::006D

2001:E7B::A60:FC9:0:B -----------> 2001:0E7B::0A60:0FC9:0000:000B
