Buffer

Definition

Buffer refers to something that lessens or absorbs the impact of a force, shock, or change. In computing, it describes a temporary storage area for data being transferred between two locations. It is also used in chemistry to describe a solution that resists changes in pH when acids or bases are added.

Etymology

The word "buffer" likely originated from the Old French word "bouffer," meaning "to puff," which was used to describe the softening of blows. The term entered English in the early 19th century, first referring to mechanical devices that absorb shock and later broadening in meaning across other fields.

Usage

The noun "buffer" is used across various contexts, from describing devices that absorb shock in transportation to software mechanisms that temporarily store data. For instance, "The railroad uses a buffer to prevent collisions," or "The video was paused due to buffering." In chemistry, a buffer solution is a common example, as it stabilizes pH in reactions.

• Neutralizer: A substance that counteracts the effect of another.

Detailed Definitions

Noun

• A device or material that absorbs impact or shock: Refers to physical mechanisms or materials used to reduce the effects of sudden forces.
  • Example: "The train has a buffer at the end of each car to prevent damage."
• A temporary storage area in computing: Refers to an allocated space in memory for temporarily holding data being transferred between systems.

• A chemical solution that resists changes in pH: Refers to solutions used in chemistry to maintain stable pH levels in reactions.
  • Example: "The laboratory prepared a buffer solution to keep the reaction steady."

Verb

• To lessen the impact or effect of something: Describes the action of softening or moderating a force, change, or influence.
  • Example: "They installed panels to buffer the noise from the factory."
• To temporarily store data in computing: Refers to the process of holding data in a buffer for smoother processing or transfer.
