About these units
DVD (2 layer, 2 side) (DVD (2L, 2S))
The dual-layer, double-sided DVD provides the maximum DVD capacity: 17.1 GB. With two layers on each side, these discs offered exceptional storage for large software packages, high-definition video masters (before Blu-ray), and professional archival applications. However, they were rarely used in consumer markets due to cost, complexity, and the inconvenience of double-sided handling. They remain an interesting pinnacle of DVD engineering—pushing the medium to its physical limits.
Character (character)
A character is not a fixed quantity of bytes but rather a conceptual unit representing a single textual symbol. Historically, characters corresponded to one byte under ASCII, allowing for 256 distinct values. With the rise of Unicode, characters now require variable-length encoding—from 1 to 4 bytes in UTF-8, or fixed widths in UTF-16 and UTF-32. This flexibility allows representation of all human writing systems, mathematical symbols, emojis, and historic scripts. Characters are the foundation of text processing, natural-language computing, and human-computer communication. Software engineering, databases, and web technologies must carefully distinguish between characters and bytes to avoid encoding errors and data loss.
