Nice. These should be very useful.
Maybe the Admin can make this a 'sticky' for east reference.

I think it would be better if it was actually accurate.

A Servo is a small device that incorporates a three wire DC motor, a gear train, a potentiometer, an integrated circuit, and an output shaft bearing.

We have changed it to read: "A servo is a small device that incorporates a TWO wire DC motor..."
Thank you for pointing this out.
Sincerely,

There's nothing that says that a servo has to be a DC motor, or a particular number of wires.
As stated on the Wikipedia articles I linked to...
What you are describing is a hobbyist RC servo. The qualifications are important!
"Servo" means any actuator drive that has a sensor, feedback loop, and controller. There are lots of servos that don't use a potentiometer, instead using higher-quality sensors (optical, magnetic, etc.) There are lots of servos that don't have a three-wire wiring harness. There are lots of servos that don't come with horns. There are lots of servos that use AC motors.
