Sisendiks

Sisendiks is the translative form of the Estonian noun sisend, meaning input or data fed to a system. The word designates the role of something as input to a process, device, or algorithm, typically indicating what is to be used or processed by the system.

In Estonian grammar, the translative case expresses a change of role or state, and sisendiks answers questions such as “milleks?” or “kelleseks?” For example, “Fail võetakse sisendiks arvutiprogrammis,” meaning the file is used as input in the computer program. Another common construction is “Sisendiks tuleb anda kasutajanimi ja parool,” which states that a username and password must be provided as input.

In computing and data processing, sisendiks is widely used to refer to data supplied to a program, device, or procedure. It can describe user input, sensor readings, or data contained in a file that serves as the input to an operation. The term appears in technical documentation, software interfaces, and instructional material to specify what data should be used as input.

Relation to related terms: sisend refers to the general concept of input, while sisendiks is the grammatical form used when the input is stated as the role or purpose of something within a sentence. In contrast, väljund or output denotes the data produced by a system after processing the input.
