A NOT gate (also often called Inverter) is a logic gate. It takes one input signal. In logic, there are usually two states, 0 and 1. The gate therefore sends 1 as output, if it receives 0 as input. Alternatively it received 1 as input, and sends 0 as output.
Generally, below 0.5V is 0, and 4–5V is 1.
