9.7. Input and Output (I/O)

Gate A device that performs a basic operation on electrical signals, accepting one or more input signals and producing a single output signal
Circuit A combination of interacting gates designed to accomplish a specific logical function
- Create working circuits Logic.ly
Logic diagram A graphical representation of a circuit; each type of gate has its own symbol
- Review of NOT, AND, OR
- Logic Gate Simulator with descriptions of NOT, AND, NAND, OR, NOR, XOR
- Logic Gate Puzzler
Transistor A device that acts either as a wire or a resistor, depending on the voltage level of an input signal (like a switch)
- Transistors, How do they work? (6:52)
- How Does a Transistor Work? (5:59)

Truth table A table showing all possible input values and the associated output values - Truth Tables
- Truth Table Generator
  - NOT ¬A
  - AND A ∧ B
  - OR A ∨ B
  - IF (material conditional) A => B
- Other Truth Tables
  - XOR A ⊻ B
  - NAND
  - and NOR and
Number systems
- Converting with remainder method
- Binary numbers are usually grouped with 8 digits, oct with 3, and hex with 4, using leading 0s when necessary.
- All number systems could be denoted using a subscript at the end. Hex is often written with a 0x at the beginning. Oct is often written with a 0o at the beginning.
