An editor gives thought an address. Before a system can build itself, it needs a place where its own instructions can be inspected, changed and composed.

An editor gives thought an address. Before a system can build itself, it needs a place where its own instructions can be inspected, changed and composed.
The assembler crosses the semantic boundary: names become opcodes, addresses become bits, and a symbolic description becomes something the processor can execute.
The kernel owns the privileged boundary. It schedules execution, maps memory, receives interrupts and mediates devices—turning bare hardware into a place where other programs can exist.
