| We cannot
understand how a bird flies by only studying |
||||||
| its wings, but
need, in addition, an aerodynamic theory |
||||||
| of lift
generation by the flow patterns around the wings. |
||||||
| We cannot
understand how a computer works by only |
||||||
| studying the
transistors on the circuit boards and their |
||||||
| connections, but
need, in addition, concepts of operating |
||||||
| system, data structure, and
application programs. |
