Full duplex
Simplex
Transmits signals in one direction
Half Duplex
, Transmits signals in either direction but only One Direction at a time
Direct current (DC)
Refers to a study value that does not change the polarity of the voltage or the direction
of the current
Frequency
1 cycle in 1 s = 1 Hz
Full duplex
Transmit signals in both directions at the same time
Capacitance 1
Properties of conductors that allows storage of electric charges when potential
