# 4 Input Logic Gate
Below is a list of all 16 possible input combinations for a 
4-input logic circuit (A, B, C, D). For each row, determine 
what the output should be based on your logic design, and 
enter either 0 (off/false) or 1 (on/true) in the Output column.

A |	B	| C	| D	| Output
----------------------
0	| 0	| 0	| 0	| 
0	| 0	| 0	| 1 | 
0	| 0	| 1	| 0	| 
0	| 0	| 1	| 1	| 
0	| 1	| 0	| 0	| 
0	| 1	| 0	| 1	| 
0	| 1	| 1	| 0	| 
0	| 1	| 1	| 1	| 
1	| 0	| 0	| 0	| 
1	| 0	| 0	| 1	|

# Reflection Questions
Answer the two reflection questions below

1. What did this project help you understand about how computers 
   or electronics ‘think’?

2. How do logic gates help us understand how semiconductors work 
   in modern technology?
