Complete the sentence by using these words: denary, 2, 10, binary, analogue, digital - Answer- analogue digital ...

Transistor correct answers A tiny switch that is activated by electronic signals pixel correct answers Short for "picture element" it is the fundamental unit of a digital image, typically a tiny square or dot which contains a single point of color of a larger image. Why do we use transistors correct answers Transistors have two states to represent on and off Binary correct answers A way of representing information using only two options. (1 = on or true, 0 = off or false) How many ...
