10 Facts About Data transmission
1.
2.
In most textbooks, the term analog Data transmission only refers to the Data transmission of an analog message signal by means of an analog signal, either as a non-modulated baseband signal or as a passband signal using an analog modulation method such as AM or FM.

10.
However, electrical wire parallel data transmission is therefore less reliable for long distances because corrupt transmissions are far more likely.
