Computer Architecture and Design Question:

Answer #1
65 to decimal
65/16=4
remainder=1

==41 decimal
decimal to binary
101001

Answer #2
65Hex= 101 decimal = 1100101 binary

Answer #3
A hex digit can range from 0-A (0-15 in decimal). Thus each hex digit requires 4 bits.
6(Hex)=6(Dec)=0110
5(Hex)=5(Dec)=0101
Therefore 65(Hex)=01100101

Answer #4
A hex digit can range from 0-F (0-15 in decimal). Since 15(Dec)=1111(Bin), each hex digit requires 4 bits.
6(Hex)=6(Dec)=0110
5(Hex)=5(Dec)=0101
Therefore 65(Hex)=01100101

Answer #5
5 => 0101
6 => 0110
we can directly convert each digit individually.
so 65 => 01100101

Answer #6
Each digit in hex can represent up to 4 binary bits (nibble).
So, a hex number with multiple digits can be converted into its binary equivalent by converting each hex digit to its binary equivalent and concatenating the bits in the same order as the digits in the hex number appear.
6 hex = 0110 in binary
5 hex = 0101 in binary
Hence:
65 hex in binary is
= \\"0110\\" concatenated with \\"0101\\"
= 0110_0101
= \\"01100101\\"
= 1100101 (removing leading zeroes)

Answer #7
0x65
0x60 + 0x05
0110 0000 + 0000 0101
0110 0101
41 decimal is
0010 1001
0x29

Answer #8
Shortcut:
One hex digit is 4 bit binary.
And you can directly concatenate the binary representation of each digit in the hex to get bin representation.
So.. 5 ==> 0101 && 6 ==>0110
hence 65 ==> 01100101

Answer #9
65 hex is 0110 (6) 0101 (5) == 1100101
65 hex = 101 decimal

Answer #10
0x65 = 0110 0101
0x6 0x5

Answer #11
6(Hex) = 0110
5(Hex) = 0101
65(Hex) = 0110 0101

Answer #12
01101010

Answer #13
01100101
