The Buffer,
A buffer is often used in digital logic to condition a signal, and also to buffer a signal up to the level needed to drive the next stage, basically you can think of it as simply a hopped up amplifier who's output is either all the way ON or completely OFF,

The NOT Gate,
also called an Inverter, or Inverting Buffer,
The NOT Gate does exactly the same thing as the Buffer except its output is inverted,

The NAND Gate,
the NAND Gate is simply an AND Gate with its output inverted, so its output goes low when both its inputs are high,
