The terminals on a MOSFET are called the "Source", "Drain", and "Gate". Just as with a bipolar junction transistor (BJT) the direction of current flow will be based on the doping configuration of the semiconductor. In a MOSFET, the doping configuration can be either n-channel or p-channel, but with MOSFETS, they also come in a "normally on" or "normally off" configuration, which is specified by being either "depletion mode" or "enhancement mode", respectively.
A shorted output, bad output transistor. need more info.
A transistor acts like a valve or gate that opens and closes, and allows a current to flow. Since the amount of current that flows is controlled by another input, they can be used to make amplifiers. Carbon microphones and vacuum tubes have the same property, and so have also been used to make amplifiers historically.
A transistor used as a switch is operated in saturated mode, where the ratio of base-emitter current over collector-emitter current is far more than hFe, or beta gain. The transistor is either fully on or fully off in this mode. A transistor used as an amplifier is operated in linear mode, where the ratio of base-emitter current over collector-emitter current is equal to or less than hFe, or beta gain. The transistor is partially on in this mode, and is operating as a current controlled current sink.
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.

The terms "source" and "sink" could be used for inputs but are more commonly used for output terminals. If a device has a "source" output, it supplies current to an external device by connecting it to some power source. If the device is a "sink" it supplies current to some other device by draining it away to ground (often -ve). This is where the names "source" and "drain" came from in the naming of Field Effect Transistor terminals. Many devices have both "sink" and "source" capabilities such as most operational amplifiers. Most of the time the "sink" and "source" capabilities of such a device are different because N material conducts better then P material.
usually power source where power comes from logic gates outputs are commonly called source or sink say the power source to the package is positive (VCC is +5) to call the output a source we would use an NPN transistor with the collector connected to +5V the base goes to the logic the emitter is the output terminal the output is the source of +5v sink output would have the emitter grounded base to logic the collector is the output so the output will sink positive voltage to ground A BUFFER usually has two output transistors one for source one for sink and can do either or both

A; Must define the transistor type and its mode of application if you expect an answer. It has the capabilities to conduct both way on either type dueing saturation mode. Hope that helps
sink node is source
In what?this is true in TTL logic ICs because the pulldown drive transistor is strong and the pullup drive transistor is weakthis is false in CMOS logic ICs because both pulldown and pullup transistors are identicalin other devices it varies
