Binary file handling operates on the principle that non-text data must be accessed in 'rb' mode to retrieve byte string objects rather than text strings, as binary formats lack inherent newline delimiters. The core theoretical mechanism for managing large-scale binary data involves chunked reading via fixed-size blocks to prevent excessive memory consumption, distinguishing this approach from the line-by-line iteration used in text processing. This concept belongs to computer science file I/O theory, specifically within the domain of data serialization and low-level storage manipulation, where abstract byte manipulation supersedes high-level text interpretation for arbitrary binary formats.
