| Term | Definition |
|---|---|
| Binary form | Represents the flow of electricity in wires and transistors 1 - electricity flowing 0 - electricity absent |
| Transistors | electrical components made from semiconductor materials that can act as electrically-controlled switches can be used to temporarily store data e.g some forms of primary storage Can be used to preform calculations |
| Logic gate explanation | Multiple transistors can be arranged together to form more complex "switches" that only allow electricity to flow through if all or some of the transistors are "on" |
| Logic gates 1 | AND - only outputs 1 if all inputs are 1 (A.B) OR - outputs 1 if there is at least a singular input of 1, otherwise 0 (A+B) NAND - only outputs 0 if all inputs are 1 NOR - outputs 0 if there is at least a singular input of 1, otherwise 1 |
| Logic gates 2 | XOR - outputs 1 if there is only a singular 1 input, otherwise 0 XNOR - outputs 0 only if there is a singular 1, otherwise 1 NOT - inverts the input (Ā) |
| Logic circuits | Made up of multiple logic gates Can preform functions such as adding and storing data |
| Ways of solving Booleans | Evaluation via definition Truth tables (shows each combination) |
