# Lesson 2.1 Key Terms

TermDefinitionSentence
Logic Circuit Any circuit that behaves according to a set of logic gates In order to set up the logic gates you have to use the logic circuits
Logic Diagram A diagram, similar to a schematic, showing the connection of logic gates I didn't understand how the logic gates were connecting so i looked at the logic diagram
Maxterm A sum term in a Boolean expression where all possible variables appear once in true or complement form When a sum term has all the possible variables appearing once it's an example of a maxterm
Most Significant Bit The leftmost bit of a binary number. This bit has the number's largest positional multiplier. The most significant bit has the greatest numerical value
Product-of-Sums A type of Boolean expression where several sum terms are multiplied together. When the sum terms are multiplied together then it's an example of product-of-sums
Product Term A term in Boolean expression where one or more true or complement variables are AND'ed I learned that a product term complements variables that are AND'ed
Sum-of-Products A type of Boolean expression where several product terms are summed together When the sum terms are added together then it's an example of sum-of-products
Sum Term A term in Boolean expression where one or more true or complement variables are OR'ed There is a lot of Boolean expressions such as sum term which complement variables that are OR'ed
Truth Table A list of all possible input values to a digital circuit, listed in ascending binary order, and the output response for each input combination I showed my truth table to my instructor to present him possible input values
Minterm A product term in a Boolean expression where all possible variables appear once in true or complement form When the product terms has all the possible variables appearing once then it's an example of a minterm
DeMorgan's Theorem Theorem stating that the complement of a sum equals the product of the complements and stating that the complement of a product equals the sum of the complements I used DeMorgan's Theorem to see if the sum equals to the product
Distributive Property The property that allows us to distribute across several OR functions Several OR functions allows you to use distributive property
Least Significant Bit The rightmost bit of a binary number. This bit has the number's smallest positional multiplier The least significant bit has the lowest numerical value

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
