noun

1. British informal, offensive a stupid or bumbling man (esp in the phrase old buffer)

n.1835, agent noun from obsolete verb buff “make a dull sound when struck” (mid-16c.), from Old French bufe “a blow, slap, punch” (see buffet (n.2)); hence also “something that absorbs a blow.” v.1894, from buffer (n.). Related: Buffered; buffering. n.

1. A substance that minimizes change in the acidity of a solution when an acid or base is added to the solution.

v.

1. To treat a solution with a buffer.

1. Chemistry A substance that prevents change in the acidity of a solution when an acid or base is added to the solution or when the solution is diluted. Buffers are used to make solutions of known pH, especially for instrument calibration purposes. Natural buffers also exist in living organisms, where biochemical reactions are very sensitive to changes in pH.
2. Computer Science A device or an area of a computer that temporarily stores data that is being transferred between two machines that process data at different rates, such as a computer and a printer.

In chemistry, the components of a solution that can neutralize either an acid or a base and thus maintain a constant pH.
