The distance over which data moves within a computer may differ from a few thousandths of an inch, as is the case within a one IC chip, to as much as lot of feet along the backplane of the main circuit board. Over these small distances, digital data might be transmitted as direct, two-level electrical signals over simple copper conductors. Except for the fastest computers, circuit designers are not very concerned about the shape of the conductor or the analog characteristics of signal transmission.
- Light source is LED (light-emitting diode) or a laser - LEDs are cheaper however not as precise (unfocused) limited to short-distance use - Lasers is able to have a narrow
What is Frequency borrowing In the simplest case, frequencies are taken from adjacent cells by congested cells. The frequencies can also be assigned to cells dynamically.
