Endianness

Let's say a hex string: 0x1122334455667788

In Little Endian: 0x8877665544332211

In Big-Endian: 0x1122334455667788

x86 and x86-64 both use Little-Endian formats

Example

We can now jump to next instruction and examine rax

This concludes that the CPU I am using is little endian in nature.
