What is the difference between front and back O2 sensors?

Most O2 sensors have an internal heating element so that they can reach the required temperature more quickly and remain there even during idling, when exhaust temperatures can drop below the threshold for oxygen sensor function. Front O2 sensors analyze the exhaust coming directly from the engine.
