How did Boole expand the field of logic to create Boolean algebra. |
Boole devised a set of symbols and formal rules which brought logic into the realm of mathematics. |
|
|
What is AND?
|
Only outputs 1 if both inputs are 1. (eg input A and input B are both 1) . |
|
|
What is OR? What is the written OR gate character usually used in computing? |
Outputs 1 if input A or input B are 1. (ie, if B is 1 A is 0, or A is 1 B is 0, or both are 1) + |
|
|
What is NOT? What is used in computing to represent not? |
Returns the output that the input is not. A line/bar is drawn above the value. |
|
|
What is XOR? How is XOR written in computing? |
The same as an OR gate except returns 0 if both inputs are 1. ⊕ |
|
|
What is NAND? |
Not and |
|
|
What is NOR ? |
Not or |
|
|
