Front

What does "binary" mean, literally?

Back

two states

Front

In computers, the "on" and "off" states correlate to...

Back

if electricity is flowing or not

Front

One reason computers use binary is because it prevents confusion and crossed signals. Another reason is a branch of math already existed, called...

Back

Boolean Algebra

Front

Which of these is NOT a fundamental operation in Boolean algebra? NOT, AND, OR, YET

Back

YET

Front

A logic table for NOT that has an input of TRUE will show an output for...

Back

FALSE

Front

The AND Boolean operation takes two inputs but still has a single output. What must the inputs be for the output to match?

Back

Both inputs must match to have the output also match.

Front

For the OR operation....

Back

only one of the inputs needs to be TRUE for the output to be TRUE

Front

What is the difference between an Exclusive OR (XOR) and a regular OR?

Back

If both inputs are true, the XOR is false.

Front

When computer engineers are designing processors, they _______ work at the transistor level.

Back
