Question Answer
Why do Computers use Binary Logic? > Can only recognise the presence or absence of current (or voltage in the case of analogue electronics) > The voltage in a computer is measured as high or low - 1 or 0 > Electronic logic gates take these inputs and produce a single output, which can be used in later gates, allowing for complex circuits
What is a NOT Gate and its Symbol? > Inverts the input > Q = ¬A > ¬1 = 0 and visa versa
What is an AND Gate and its Symbol? > Outputs 1 only if both inputs are 1 > Q = A ∧ B > 1 ∧ 1 = 1 > 1 ∧ 0 = 0 > 0 ∧ 0 = 0
What is an OR Gate and its Symbol? > Outputs 1 only if any inputs are 1 > Q = A ∨ B > 1 ∨ 1 = 1 > 1 ∨ 0 = 1 > 0 ∨ 0 = 0
What is an XOR Gate and its Symbol? > Outputs 1 only if only one input is 1 > Q = A ⊻ B > 1 ⊻ 1 = 0 > 1 ⊻ 0 = 1 > 0 ⊻ 0 = 0
