A normal configuration for a BJT is Class A Common Emitter. In this configuration, the BJT operates as an inverting amplifier. Driven into saturation, it is a inverting switch, hence the designation NOT gate.
Transistor can act as a gate. But its not a gate. In BJT(Bipolar Junction Transister) type transisters there are two P-N juntions. That means if we need we can use it as a NOT gate. Actually gate ICs (Intergrated circuits) are also build using transistors. (Example : TTL(transister-transister logic))

MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
The storage element of EEPROM is a floating gate transistor. This transistor can trap or release electrons, which alters the conductivity of the transistor and determines whether a binary value (0 or 1) is stored in a specific memory cell.
The input of a transistor is typically referred to as the "gate" in a field-effect transistor (FET) or the "base" in a bipolar junction transistor (BJT). In both cases, the input controls the flow of current through the transistor, allowing it to function as a switch or amplifier in electronic circuits. The gate or base receives the input signal that modulates the transistor's operation.
A transistor acts like a resistor when Gate is connected to Source.

For a BJT transistor the three basic elements are collector, base and emitter. For a FET transistor are drain, gate and source which are analogous for the BJT parts mentioned before.

Field Effect Transistor A: basically a silicon bar where the conduction is controlled by a field since there is no connection to the gate the impedance is very high
The source resistor in a transistor circuit helps to stabilize the operating point by providing negative feedback, which reduces distortion and improves linearity by controlling the amount of current flowing through the transistor. The gate resistor, on the other hand, is used to limit the input current to the gate terminal of a field-effect transistor (FET) or to reduce oscillations in amplifier circuits, ensuring stable operation and protecting the gate from voltage spikes. Together, these resistors enhance circuit performance and reliability.
A thyristor or silicon controlled rectifier (SCR), as they are sometimes known, consists of two transistors. A pulse on the gate turns on the second transistor which then turns on the first transistor in the combination. Turning on the first transistor enables anode current to flow and maintains a base current for the second transistor which keeps it on.See the Related link for an equivalent circuit for an SCR or thyristor.
