1. PWM stands for:

   1. Pin Work Mode.

   2. Pulse Weight Modulation.

   3. Pulse Width Modulation.

2. In the Intel Galileo Gen 2 board, the pins labeled with the following symbol as a prefix for the number can be used as PWM output pins:

   1. Hash sign (#).

   2. Dollar sign ($).

   3. Tilde symbol (~).

3. A 100% duty cycle (always signal in the ON status) in a PWM pin will generate a steady voltage equal to:

   1. 0 V.

   2. The voltage specified in the position in which the IOREF jumper is located.

   3. 6 V.

4. A 0% duty cycle (always signal in the OFF status) in a PWM pin will generate a steady voltage equal to:

   1. 0 V.

   2. The voltage specified in the position in which the IOREF jumper is located.

   3. 6 V.

5. A 50% duty cycle in a PWM pin with a LED connected to it will generate the same result as a steady voltage equal to:

   1. 0 V.

   2. Half the voltage specified in the position in which the IOREF jumper is located.

   3. 6 V * 0.5 = 3 V.
