, ●● Simplex
Answer: Transmits signals in one direction
●● Half Duplex
Answer: Transmits signals in either direction but only One Direction at a
time
●● Direct current (DC)
Answer: Refers to a study value that does not change the polarity of the
voltage or the direction of the current
●● Frequency
Answer: 1 cycle in 1 s = 1 Hz
●● Full duplex
Answer: Transmit signals in both directions at the same time
●● Capacitance 1
Answer: Properties of conductors that allows storage of electric charges
when potential differences (voltage) exist between the Conductors
●● Capacitance 2
