About these units
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.
DVD (2 layer, 1 side) (DVD (2L, 1S))
A dual-layer, single-sided DVD stores 8.5 GB using a semi-transparent layer that allows the laser to focus at two depths. This innovation enabled longer movies, higher-quality video, and special editions packed with supplemental content. Dual-layer DVDs became standard for commercial video distribution and professional data storage. Although burning DL DVDs at home was initially slow and expensive, they played a crucial role during the transition to higher-capacity optical storage.
