What does unbuffered mean?
Unbuffered means without a buffer, or without an intermediate holding area used to manage differences in the timing, speed, or arrival of data. The word is most common in computing and electronics, where it describes processes, interfaces, or modes that pass data directly from one component or system to another. An unbuffered stream, for example, may reach its destination as soon as it is produced rather than being collected in a temporary queue. This directness can improve immediacy and reduce memory use, but it may also expose the system to timing irregularities or make handling less flexible. Outside technical writing, unbuffered can more generally suggest something immediate, direct, or not moderated by a holding stage. The word is uncommon in everyday speech, and its use usually signals a specialized or deliberately technical context.
adjectiveNot buffered; lacking an intermediate buffer or holding area. In computing and electronics, it describes data or a process handled or transmitted without a buffer, often without smoothing differences in timing, speed, or delivery.
- Lacking a buffer or intermediate storage area, especially in computing, electronics, or data transmission.
"The application writes the incoming data in unbuffered mode so that each record is processed immediately."
"The application writes each incoming record in unbuffered mode."
"The display controller receives video data through an unbuffered interface."
Unbuffered data skips the holding pen: it moves straight from its source to its destination without waiting in a queue.

Where does unbuffered come from?
Unbuffered is a modern English formation made by combining the prefix un- with buffer and the adjective-forming suffix -ed. Its base word, buffer, was borrowed into English from French; in English it developed meanings associated with cushioning impacts and, later, temporarily holding data for processing.
How unbuffered is actually used
Chiefly a technical term in computing, electronics, and data transmission. It normally indicates that data is passed or processed directly without an intermediate holding area; in other contexts, it can imply a lack of delay or smoothing.
