Compare with Definitions
Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output.
Buffer
One that buffs, especially a piece of soft leather or cloth used to shine or polish.
Amplifier
One that amplifies, enlarges, or extends.
Buffer
A buffing wheel.
Amplifier
An electronic device that is used to increase the magnitude of an electrical signal.

Buffer
Something that lessens or absorbs the shock of an impact.
Amplifier
A device that is used to increase the magnitude of an information-carrying signal.
Buffer
One that protects by intercepting or moderating adverse pressures or influences
"A sense of humor ... may have served as a buffer against the ... shocks of disappointment" (James Russell Lowell).
Amplifier
Anything that amplifies, or makes something larger or more intense.
Buffer
Something that separates potentially antagonistic entities, as an area between two rival powers that serves to lessen the danger of conflict.
Amplifier
(linguistics) An adverb that adds intensity, such as "really" or "totally".
Buffer
(Chemistry) A solution that resists a change in acidity when an acid or base is added to it, or a substance that facilitates this resistance.
Amplifier
(electronics) An appliance or circuit that increases the strength of a weak electrical signal without changing the other characteristics of the signal.
Buffer
(Computers) A device or area used to store data temporarily.
Amplifier
(music) A portable encasement that houses a large speaker, used to amplify voices and musical instruments at live performances.
Buffer
To act as a buffer for or between.
Amplifier
A lens that enlarges the field of vision.
Buffer
(Chemistry) To treat (a solution) with a buffer.
Amplifier
One who or that which amplifies.
Buffer
(Computers) To hold or collect (data) in a buffer.
Amplifier
Electronic equipment that increases strength of signals passing through it
Buffer
An elastic apparatus or fender, for deadening the jar caused by the collision of bodies; as, a buffer at the end of a railroad car.
Buffer
One who polishes with a buff.
Buffer
A wheel for buffing; a buff.
Buffer
A good-humored, slow-witted fellow; - usually said of an elderly man.
Buffer
A substance or mixture of substances which can absorb or neutralize a certain quantity of acid or base and thus keep the degree of acidity or alkalinity of a solution (as measured by pH) relatively stable. Sometimes the term is used in a medical context to mean antacid.
Buffer
A data storage device or portion of memory used to temporarily store input or output data until the receiving device is ready to process it.
Buffer
Any object or person that shields another object or person from harm, shock, or annoyance; as, the President's staff is his buffer from constant interruptions of his work.
Buffer
To add a buffer{5} to (a solution), so as to reduce unwanted fluctuation of acidity.
Buffer
An ionic compound that resists changes in its pH
Buffer
An inclined metal frame at the front of a locomotive to clear the track
Buffer
(computer science) a part of RAM used for temporary storage of data that is waiting to be sent to a device; used to compensate for differences in the rate of flow of data between components of a computer system
Buffer
A power tool used to buff surfaces
Buffer
A cushion-like device that reduces shock due to contact
Buffer
An implement consisting of soft material mounted on a block; used for polishing (as in manicuring)
Buffer
Add a buffer (a solution);
Buffered saline solution for the eyes
Buffer
Protect from impact;
Cushion the blow
