Serial Arduino Uno

Using Arduino Networking, Protocols, and Devices

Greetings.

Im kind of new at this and I would like to know if my arduino uno has just one or two serial ports.
I mean, I can send data using serial to the PC, but is that the same serial than the one labeled in the pin 0 and pin 1?
and if those are diferent, how can I use them at the same time?

thank you so much.

You have it right, there's just one, that's using pins 0 & 1.
"Send(ing) data using serial to the PC" can take many meanings ("Processing", "Firmata", "Serial Monitor", via MAX232, etc.)

I want to comunicate 2 arduinos with the serial port (pin 1 and 0, of each) and look at what they are recibing in the serial monitor.
Can I do that?, and if that so, how can I?

If you have two arduinos then you need two serial ports, one for each.
The Arduino IDE has a 'button' for Serial Monitor. Once you upload your 'sketch' and it runs, 'click' that Serial Monitor button. That forces a Reset and then you'll see your data in the Serial Monitor window (there's also a baudrate to get right.)

Then you need 2 IDE windows open, so you can open the Serial monitor in each.
Each UNO will be on a different COM port.
