Invoer

Invoer is a Dutch term meaning input or data entry, referring to the act of providing information to a system, device, or process. In computing and information technology, invoer denotes the data that a program, service, or hardware component receives from users, other programs, or external sources. The concept is contrasted with uitvoer (output).

Common sources of invoer include keyboards, mice, touchscreens, microphones, scanners, sensors, and file uploads. In software, input may be read from keyboards via input prompts, from files, or from network streams. In programming, input data is typically parsed, validated, and transformed before it is used by algorithms or stored.

Quality and format are important aspects of invoer. Input validation and sanitization help prevent errors and security issues; normalization ensures consistency for downstream processing. Typical input formats include JSON, XML, CSV, and domain-specific structures, while interfaces may specify schemas or validation rules.

Invoer also appears in contexts such as data entry tasks in business processes, where operators enter data into forms or databases. The Dutch term integrates into user interfaces and technical documentation as the counterpart to uitvoer, and is part of common terminology for describing data flow in systems.
