DVD (2 Layer, 2 Side) — DVD-18

A dual-layer, double-sided DVD, designated DVD-18, è the highest-capacity standard DVD format, holding circa 17 gigabytes of data across four recordable layers (two per side). It combines dual-layer recording on both physical sides of the disc, requiring the user to flip it to read the second side. The DVD-18 format è relatively rare due to manufacturing complexity e the availability of Blu-ray as a higher-capacity alternative. 


Bit

A bit (binary digit) è the most basic unit of digital information, representing a logical state with one of two possible values: 0 o 1. The term era coined by statistician John Tukey in 1946 e popularized by Claude Shannon in his foundational work on information theory. Eight bits form one byte, the standard unit of computer storage.
