An input routine is a set of programmed instructions that govern the collection and processing of data or information from an external source, such as a user, a device, or a file, into a computer system or program. Its primary purpose is to facilitate the efficient and accurate transfer of data into a computer program for further processing or analysis.
The input routine typically starts by establishing a communication link or interface between the external source and the computer system. It then initiates the process of data collection by prompting or requesting the necessary information from the user or device. This may involve presenting questions or options for selection, accepting keyboard or mouse inputs, or reading data from a file or database.
Once the data is received, the input routine performs validation checks to ensure the data's integrity, accuracy, and conformity to specified rules or formats. It may verify that the input is within acceptable range, contains valid characters, or adheres to predefined patterns.
After the data passes the validation stage, the input routine transfers or stores the collected information in appropriate memory locations, variables, or data structures within the program or system. This allows subsequent processing or manipulation of the input data to produce desired results or outcomes.
In summary, an input routine is a critical component of computer systems and software programs that governs the collection, verification, and storage of data from external sources, enabling efficient and accurate data input for further processing or analysis.
The etymology of the term "input routine" can be understood by analyzing its two constituent words.
1. Input: The word "input" originated from the combination of the Latin prefix "in-" meaning "into" or "in" and the Latin noun "putare" meaning "to reckon" or "to assess". Eventually, in English, "input" came to represent the notion of providing data, information, or commands into a system or a device.
2. Routine: This word originated from the Middle French word "routine", which referred to a customary course of action or a regular, habitual procedure. The French term was derived from the Latin word "routine" or "rutina", meaning "a regular course" or "a mundane task".
Combining these two words, an "input routine" refers to a procedure or set of actions that involve providing data or information into a system or program in a regular, habitual manner.
