Does GPIOs means "usable with Out/In/InterrruptPort" ?

I have seen in the description of the netduino that it has 20 GPIOs with SPI, I2C, 2 UARTs (1 RTS/CTS), 4 PWM and 6 ADC channels. My question may seems obvious, but I'm really new to this field. (Electronics in general) Does each of these pin can be used with OutputPort/InputPort/InterruptPort ? Or does each pin have its own job and must be used only for its jobs (pin 0-1 can only handle serial etc...)

Hi Nicolas, All of the digital and analog I/O pins may be used for GPIO (general purposes input/output = InputPort/InterruptPort/OutputPort). Almost all of the pins have specialized secondary functions that you can use as well (serial, I2C, SPI, analog inputs, etc.) Welcome to the Netduino community, Chris
