How many O2 Sensors are in my car?

I'm wondering how many O2 Sensors are in my 2000 Taurus w/ 24 valve, DOHC and where they are located. Also, are the sensors for this vehicle all the same in regard to the sensor itself with just different wiring lengths?

I'm replacing (1) O2 sensor that is issuing a code. As I've looked a little farther into information on O2 sensors, given the mileage of my Taurus & the fact that none of them have ever been replaced, it seems that it would be an excellent idea to replace them all. I have heard/read that there are (3) total, but have also been told that there are four.

Also, as I have shopped for them it appears that even though there are differnt part numbers, that any of them seem ultimately to be both upstream & downstream with only the length of the wires actually being different--varying with different source sites and purchasing information. Thank you for your timely assistance.
