OR gates
An OR gate, also called a Another name given to the OR gate., uses two Data which is inserted into a system for processing and/or storage. to generate one Data which is sent out of a system.. The output is 1 (TRUE) only if either or both of the inputs are 1 (TRUE).
OR gates are represented diagrammatically as
A represents the first input. B represents the second input. Q represents the output.
A A table to list the output for all possible input combinations into a logic gate. shows, for each combination of inputs, what the output will be. An OR gate is represented in a truth table as seen below.
| A | B | Q |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
| A | 0 |

This OR gate is represented in A form of algebra which works only with two values, TRUE or FALSE. as one of:
- A OR B
- A \/ B
- A+B
