What does buffering mean?
Buffering is the process of absorbing or moderating a force, shock, or change so that whatever lies behind it feels less impact. Its most visible modern sense belongs to computing and streaming media: data is gathered into a temporary holding area called a buffer before playback, which keeps audio and video running smoothly even when the network delivers information unevenly. When that supply runs short, users see the familiar sign of a video 'buffering' — a small but universally understood frustration of the internet age. The word also appears in engineering, where materials provide buffering against vibration, in chemistry, where solutions resist swings in acidity, and in diplomacy or planning, where buffer zones separate opposing forces or absorb uncertainty. In all its senses, buffering implies patience, protection, and the smoothing out of rough edges rather than outright prevention.
The process of storing data temporarily in a buffer so it can be processed or played back smoothly, especially during streaming or transfer.
"Frequent buffering made the live broadcast nearly unwatchable."
This is by far the dominant modern sense.
The act or effect of protecting something from shock or sudden change, whether physically, chemically, or figuratively.
"Trees planted along the field edge provide buffering against strong winds."
Every time you watch a streaming video, invisible 'buffering' is quietly downloading seconds ahead of your life so the picture never has to catch up.

Etymology of buffering
Buffering derives from the verb 'to buffer,' built on the noun 'buffer,' whose earliest recorded sense was a piece of equipment that deadens a blow, appearing in English around the early nineteenth century. The word's deeper origin is uncertain, though it may relate to 'buff,' meaning leather or a dull thudding sound. From this mechanical sense the term spread naturally to chemistry, engineering, and eventually computing, where the buffer became the standard name for temporary storage that evens out the flow of data.

How buffering is actually used
Most common in technical contexts such as computing, networking, and chemistry, where it carries a neutral register; figurative everyday use ('buffering between two arguing colleagues') is less frequent but natural.
Easily confused with buffering
Buffeting refers to being repeatedly struck or tossed about by wind or waves, whereas buffering describes cushioning a blow or temporarily storing data.
