characteroriented

Characteroriented refers to systems, interfaces, or data processing that treat input and output as a stream of individual characters rather than as lines, blocks, or pages. In a characteroriented approach, each keystroke or character is processed as soon as it is received, enabling immediate feedback and per-character handling.

Historically, characteroriented I/O was common with early teletype machines and video terminals that transmitted and reacted to single characters. In such environments, users could see and edit text in real time, and applications often needed to respond to special characters (like control codes) as they arrived. Today, characteroriented behavior is still relevant in interactive programs, though it is often implemented within broader operating-system mechanisms that control buffering and input modes.

The main contrast is with line-oriented or canonical I/O, where input is buffered until a line terminator (such as a newline) is encountered. In many modern systems, terminal or console settings provide a choice between canonical (line-oriented) and non-canonical or raw (characteroriented) modes. Non-canonical mode delivers input per character, which is essential for responsive command shells, text editors, games, and applications that require immediate processing of keystrokes and special keys.

Applications of characteroriented design include interactive command interfaces, real-time text editing, and any user-facing component that benefits from per-character feedback. While line-oriented processing remains common for batch input and network protocols, characteroriented considerations continue to influence how interfaces are designed and how input handling is implemented at the software level.
