2. Now, give it a try by converting the binary number 01110110 to decimal by filling in the same table in step 1 r of 2 Pov 128 64 32 16 Cumulative Amount 4. Now, you give it a try by converting the decimal number 131 to binary by filling in the table Power of 2 128 32 16 Bit Amount Remaining 6. Use the binary to hexadecimal table to convert the binary number 01101111 to hexadecimal 0001 31 0010 32 0011 33 0000 30 0100 4 0101 35 0110 36 0111 37 1001 9 1000 8 1100 C 1011 B 1101 D 8. Try it yourself now by converting the hexadecimal number A2 into binary 3- 0011 1 30001 0 300000 2 0010 4 0100 7 0111 5 0101 8 1000 9 1001 D 1101 A E 1010 10. Now, give it a try yourself with this full 48-bit address, by converting each hexadecimal digit to 4 bits, and then concatenating all the groups of bits. D9:87:3A: BE:F2:15 12. What would the OUI be for the address given in step 10 (D9:87:3A:BE:F2:15) in both the enhanced hexadecimal representation and in binary? List them both out.

Answer 1

2nd question:

128 64 32 16 8 4 2 1
   0     1   1    1 0 1 1 0
---------------------------------
0    64 32 16 0 4 2 0

so 64+32+16+4+2=118

so for binary number 01110110   the decimal number is 118

4th question:

dividing           remainder

2)131(65            1

2)65(32          1

    2)32(16          0
  
   2)16(8          0
  
   2)8(4          0
  
   2)4(2                   0
  
   2)2(1        0
  
   2)1(          1

so the binary number is 10000011 for decimal number 131

6th question:

given binary number is 01101111 and the hexadecimal number according to table is
   0110 is '6' and 1111 is'F' so the heaxdecimal number is 6F

7th question:

given hexdecimal number is A2 according the given table
   A=1010 and 2=0010 so the binary number is 10100010
