Masking in Binary

Concept:

What if you’re only interested in the last few bits of a Binary address? How can you extract that?

Steps:

1. Your Address: 0x12345678 (In binary: 0001 0010 0011 0100 0101 0110 0111 1000)
2. Your Mask: 0x0000000F (In binary: 0000 0000 0000 0000 0000 0000 0000 1111)
3. Apply Mask: Perform a bitwise AND between the address and the mask.
   • Result: 0000 0000 0000 0000 0000 0000 0000 1000
