The MAC address or the physical address of an interface is essential for CSMA/CD communication over a network

MAC addresses are in a 48bit Hexadecimal value.  The key to converting from hex to decimal is know your place values

163 162 161 160

Remember anything to the power of 0 is always 1

4F6A = (4 x 163)+ (F[15] x 162)+ (6 x 161)+ (A[10] x 160) = 20330 (decimal)

Converting Decimal to Hex is a little more complicated it requires long division.  Each Hex value is based on the remainder of the division problem. Not the answer to the problem!

For example if the remainder of a division problem is 3 then your far right digit is 3.  I.e. _ _ _ 3

To start your problem you take the decimal number and divide it by 16.

24032/16 = 1502, with a remainder of 0
1502/16 = 93, with a remainder of 14 or E
93/16 = 5, with a remainder of 13 or D
5/16 = 0, with a remainder of 5

all of the remainders gives us the hex value of 5DE0
