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.
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.
