 No matter how a program was originally written, it eventually needs to execute
 on a [[CPU_architecture|CPU]] as a series of machine language instructions.
+
+## Example machine instruction
+
+The following machine instruction is an instruction that would be understood by
+an [[Instruction_set_architectures| ARM ISA]]. It moves the number `4` into the
+`r7` register:
+
+```
+11100011101000000111000000000100
+```
+
+This 32bit line of binary has a series of instructions embedded within it. We
+partition each part of the sequence below, from left to right, mapping it to the
+instruction:
+
+| Binary sequence | Instruction | Action |
+| --------------- | ----------- | ------ |
+| 1110            |             |        |
+| 00              |             |        |
+| 1101            |             |        |
