17
Q

RGB or red, green, and blue model is the basic model of representing colors.

18
Q

The most prevalent encoding standard used today.

19
Q

A program that translates source code into machine code.

20
Q

This gate only has ONE input signal. It takes that input signal and outputs a signal with the opposite binary state.

21
Q

This gate involves two input signals. Outputs an “ON” signal only when both inputs are “ON”.

22
Q

This gate involves two input signals. Outputs an “OFF” signal only when both inputs are “OFF”

23
Q

This gate involves 2 input signals. Outputs an “ON” signal when ONLY ONE of the inputs are “ON” (but not both).

24
Q

This gate involves 2 inputs. Outputs an “OFF” signal only when both inputs are “on”.

25
Q

This gate involves 2 input signals. Outputs and “ON” signal only when both the inputs are the same (both “ON” or both “OFF”).

26
Q
