About these units
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.
Bit (b)
A bit is the most fundamental unit of digital information, representing a binary value of 0 or 1. In physical systems, a bit corresponds to two distinguishable states—such as high/low voltage, magnetic polarity, or light/dark in optical systems. Bits form the basis of all digital computation: CPUs manipulate bits through logic gates, memory stores bits in capacitors or magnetic cells, and communication networks transmit bits as electrical pulses or photons. Although extremely small in size, bits accumulate into vast structures—from kilobytes of text to petabytes of cloud storage. Every digital phenomenon—files, images, videos, software—ultimately reduces to sequences of bits. The bit is the "atom" of information.
