Logic Gates

For the AND Boolean operation, the output is only true if _____

• one input is true

• one input is false

• both inputs are true

• both inputs are false

Two transistors connected in series, with two inputs and one output, act like ______

• a NOT gate

• an AND gate

• an OR gate

• an IF statement

Which Boolean operator is built from two transistors in parallel?

• NOT

• AND

• OR

• IF

Using an OR gate, it one transistor is on and the other is off, the output is ________

• off

• on

• indeterminate

• negated

Which logic gate is commonly represented by a "Letter D" symbol?

• NOT

• AND

• OR

• XOR

The only time an XOR is true is when _______

• both inputs are false

• both inputs are true

• one input is true and the other input is false

• the output is grounded

When we use symbols for logic gates, rather than transistors, we are moving up _____

• a row on a logic table

• a layer of abstraction

• the ladder of complexity

• the trophic pyramid

With a single transitor, if we turn the input on, ______

• the output is also on

• the output is off

• the input is negated

• it doesn't do anything

Which logic gate is commonly represented by a "spaceship with a smile"?

• NOT

• AND

• OR

• XOR

When an input to a logic chip has no connection to positive or negative, the logic gate will freak out. That condition, not being connected is called:

• Pulling Down

• Drifting

• Floating

• Lifting
