Understanding memory addresses and endianness
When looking at the memory, the data is represented in hexadecimal characters 0 - F, each of which represents a value of 0 - 15. For example, the value 0 in hexadecimal would be represented as 0000 in binary and the representation of F would be 1111 in binary.
Using hexadecimal makes it easier to read memory addresses and easier to write them as well. Since we have 32-bit memory addresses, there would be 32 positions for specific bits. Since each hexadecimal value represents four bits, the equivalent representation can be done in eight hexadecimal characters. Keep in mind these hexadecimal characters are paired so that they represent four pairs.
Intel x86 platforms use a little endian notation for the ...
