•Programs are stored the same
way, as a buffer of numbers. A program that reads someone’s last name and repeats it to
them is compiled into a series of instructions that Norman understands. Each instruction has a unique number. For example,
–23 = “Copy the number from the next mailbox and hold
that piece of paper in your left hand.”
–188 = “Put the piece of paper in your left hand into the
mailbox with the box number written on the
piece of paper in your right hand.”
