Name and describe the six boolean gates that can be incorporated into circuits and can be combined to form more sophisticated operations:
- NOT - one input; inverts the input value
- AND - true only if both inputs are true
- OR - true if either (or both) operands are true
- NAND - true UNLESS both inputs are true (opposite of AND)
- NOR - true only if both inputs are false (opposite of OR)
- XOR - true only if ONE AND ONLY ONE input is true
What is a transistor?

A transistor is a relatively inexpensive mechanism for implementing boolean operators in circuitry.
Describe how to create a NOT gate using transistor(s).
Describe how to create a NAND gate using transistor(s).
Describe how to create a AND gate using transistor(s).
Describe how to create a NOR gate using transistor(s).
Describe how to create a OR gate using transistor(s).
Describe how logic gates can be used to perform simple bit addition.
- When adding binary digits there are 2 sets of two possibilities; the sum of the two digits can be 0 or 1, and the digit carried can be 0 or 1.
- Note that the sum bit can be determined using the XOR operation, while the carry bit can be determined using the AND operation.
- Multiple bit addition can be implemented by extension of this concept.
