The process of obtaining data from various sources and converting it into a format that a computer can use is a fundamental operation in numerous fields. This process transforms raw information, which can exist in analogue or digital form, into a machine-readable representation. For example, scanning a document and saving it as a PDF file, or using sensors to record temperature readings, are both instances of this critical procedure.
This acquisition of structured or unstructured information is essential for analysis, decision-making, and process automation. Its accuracy and efficiency directly impact the reliability of subsequent operations. Historically, this was a labor-intensive manual task, but technological advancements have led to automated methods, significantly increasing speed and reducing errors. The ability to efficiently obtain information provides competitive advantages, enabling organizations to respond quickly to market changes and customer needs.
