| electricity | FUNDAMENTAL PROPERTY OF MATTER CAUSED BY THE MOTION OF ELECTRONS, PROTONS, OR POSITRONS AND MANIFESTING ITSELF AS ATTRACTION, REPULSION, LUMINOUS AND HEATING AFFECTS. |
| electro static disc warge | A FLOW OR SPARK OF ELECTRICITY THAT ORIGINATES FROM A STATIC SOURCE SUCH AS A CARPET AND ARCS A GAP TO ANOTHER OBJECT. |
| electrons | PARTICLES WITH A NEGATIVE CHARGE. |
| protons | PARTICLES WITH A POSITIVE CHARGE. |
| digital signal | LANGUAGE OF COMPUTERS COMPRISING ONLY TWO STATES, ON AND OFF WHICH ARE INDICATED BY A SERIES OF VOLTAGE PULSES. |
| impedance | EQUIVALENT TO RESITANCE BUT FOR AC AND PULSED CIRCUITS. |
| frequency modulation | MODULATION TECHNIQUE IN WHICH SIGNALS OF DIFFERENT FREQUENCIES REPRESENT DIFFERENT DATA VALUES. |
| analog transmission | SIGNALS TRANSMISSION OVER WIRES OR THROUGH THE AIR IN WHICH INFORMATION IS CONVEYED THROUGH VARIATION OF SOME COMBINATION OF SIGNAL AMPLITUDE, FREQUENCY, AND PHASE. |
| attenuation | LOSS OF COMMUNICATION SIGNAL ENERGY. |
| phase modulation | BEGINNING AND ENDING POINTS OF A GIVEN CYCLE. |
| direct current | ELECTRICAL CURRENT THAT TRAVELS IN ONLY ONE DIRECTION. |
| neutrons | PARTICLES WITH NO CHARGE. |
| propagation | TIME REQUIRED FOR DATA TO TRAVEL OVER A NETWORK. |
| circuit | COMMMUNICATONS PATH BETWEEN TWO OR MORE POINTS. |
| amplitude modulation | MODULATION TECHNIQUE WHEREBY INFORMATION IS CONVEYED THROUGH THE AMPLITUDE OF THE CARRIER. |
| alternating current | ELECTRICAL CURRENT THAT REVERSES ITS DIRECTION REGULARLY AND CONTINUALLY. |
| oscilloscope | ELECTRONIC DEVICE USED TO STUDY ELECTRICAL SIGNALS. |
| multimeter | TEST EQUIPMENT FOR MEASURING VOLTAGE, CURRENT, RESISTANCE, AND POSSIBLY OTHER ELETRICITY QUANTITIES AND DISPLAYING THE VALUE IN NUMERIC FORM. |
| conductor | MATERIALWITH A LOW RESISTANCE TO ELECTRICAL CURRENT |
| latency | DELAY BETWEEN THE TIME A DEVICE REQUESTS ACESS TO A NETWORK AND THE TIME IT IS GRANTED PERMISSION TO TRANSMIT. |
