Logic Gates (CS 9-1)

What are logic gates?

• Logic gates are the same as logic diagrams
• Logic gates are special circuits built into computer chips
• Logic gates are the automatic doors in buildings.
• Logic gates are theories about logics.

What are the functions of logic gates?

• They receive binary data
• They apply a boolean operation
• They output a binary result
• All of them

Where are logic gates used in real life?

• They are only built into smartphone chips.

• They are built into all digital electronic chips.

What are logic diagrams?

• They are the logic gates.
• They are symbols to represent logic gates and circuits.
• They are the diagrams for electronic designs.
• They are charts that show how computer programs are executed step by step - the flow.
