​KembaraXtra-Computer Terms – bipolar:
The term bipolar refers to a system or condition that has two opposite states or polarities. In general usage, it describes something that can operate with two contrasting conditions, such as positive and negative. This concept is often applied in electronics and computing where signals or devices function using two opposing states.
In data transmission and digital processing, a bipolar signal uses opposite voltage polarities to represent binary values. For example, a positive voltage may represent a logical value of one while a negative voltage represents zero. In electronics, the term also describes certain transistors that use two different types of electrical charge carriers in their operation.
