The term refers to written material lacking auditory elements. It is a medium that relies solely on the visual interpretation of text and illustrations, absent of any integrated audio playback or interactive sound components. As an example, a traditional novel or textbook, presented purely in print or digital text format, falls under this classification.
This format possesses enduring value in fostering literacy, encouraging focused reading comprehension, and promoting individual cognitive development. Its historical significance lies in its foundational role in education and knowledge dissemination, predating the integration of multimedia technologies into learning resources. The absence of auditory cues necessitates active engagement with the written content, facilitating deeper processing and retention.
