- 1Why 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 - 2What is a NOT Gate and its Symbol?> Inverts the input
> Q = ¬A
> ¬1 = 0 and visa versa - 3What 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
- 4What 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
- 5What 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
