Keyword Definition
AND Gate Logic gate that outputs true only when all of its inputs are true
AND Operator An operator that returns true if both operands are true.
Full Adder Circuit that adds three binary digits and outputs the sum and carry
Half Adder Circuit that adds two binary digits and outputs the sum and carry
Logic Gates Basic components of digital circuits that perform logical operations
Logical Operator An operator that operates on logical values, such as true and false.
NAND Gate Logic gate that outputs true unless all of its inputs are true
NOR Gate Logic gate that outputs true only when all of its inputs are false
NOT Gate Logic gate that inverts the input signal
NOT Operator An operator that returns the opposite of a logical value.
OR Gate Logic gate that outputs true when at least one of its inputs is true
OR Operator An operator that returns true if at least one operand is true.
XNOR Gate Logic gate that outputs true when the number of true inputs is even
XOR Gate Logic gate that outputs true when the number of true inputs is odd
XOR Operator An operator that returns true if exactly one operand is true.
