Diskas

Diskas is a Lithuanian noun meaning disc or disk. It refers to a flat, circular object that can store information and is used in technology to name both physical media and, in some contexts, software representations of storage. In everyday language, diskas can denote data storage devices such as a hard disk (kietasis diskas) or a floppy disk (disketė), and it is also applied to optical media like CDs, DVDs, and Blu-ray discs.

In computing, diskas designates hardware components that store digital information. Hard disks are magnetic storage devices that spin while data is read or written. Solid-state drives store data on flash memory and have no moving parts. Optical disks—CDs, DVDs, and Blu-ray discs—are used to distribute software, media, and archival data.

Etymology traces diskas to the Latin discus, via European languages, reflecting the original meaning of a flat, round object. The term forms compound expressions such as kietasis diskas (hard disk) and optinis diskas (optical disk), while diskas by itself remains a general term for a round storage medium or, more loosely, for a round flat object used to hold information. The word is common in technical documentation, educational texts, and everyday speech when discussing storage technology.
