A voltage buffer is a circuit that will buffer a source from an output.
the common collector can use as voltage buffer
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level.If the voltage is transferred unchanged (the voltage gain Av is 1), the amplifier is a unity gain buffer; also known as a voltage follower because the output voltage follows or tracks the input voltage. Although the voltage gain of a voltage buffer amplifier may be (approximately) unity, it usually provides considerable current gain and thus power gain
Common collector amplifier can be used as a voltage buffer and in impedance matching
Do you mean 'battery'
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.

A buffer is merely a temporary storage used in conjunction with computation.

Voltage is
A voltage buffer, also known as a voltage follower, is an electronic circuit that provides high input impedance and low output impedance, effectively isolating the input from the output. It is commonly implemented using operational amplifiers (op-amps) configured in a specific way where the output directly connects to the inverting input, while the non-inverting input receives the input signal. This configuration allows the buffer to maintain the same voltage level at the output as at the input, while preventing the input source from being loaded down. Voltage buffers are often used in signal processing to prevent distortion and to drive heavy loads.
A buffer state is generally interpreted as a state that lies between two hostile states
The mean load voltage, in other words the average voltage, is zero in an ac system.
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
BDT means "Buffer Descriptor" in the USB jargon
it means storage is full.
