Unfragmented

Unfragmented is an adjective describing something that has not been separated into fragments; it denotes continuity, integrity, or wholeness. The term combines the prefix un- with fragment, and is widely used across disciplines to indicate that components exist in a single, cohesive unit rather than as discrete pieces. The precise meaning depends on the domain, but the common thread is the absence of fragmentation.

In ecology and conservation, an unfragmented habitat or landscape refers to a contiguous area of suitable environment without major breaks such as roads, urban development, or large clearings that impede movement and gene flow. Unfragmented ecosystems support larger populations, more resilient species interactions, and better biodiversity. Fragmentation is reduced by maintaining habitat connectivity, implementing ecological corridors, and limiting land-use changes that split habitats.

In information technology, unfragmented memory or storage describes a state where free space is contiguous, or files are stored without scattered blocks, enabling efficient allocation and faster access. Fragmentation occurs as data are written and deleted over time. Defragmentation tools reorganize memory or storage to restore contiguity; however, memory management in modern systems and the use of solid-state drives can lessen the relevance of fragmentation for performance.

Usage of unfragmented can also be metaphorical, applied to ideas, narratives, or identities described as coherent or cohesive rather than disjointed. In scholarly writing, the term is typically qualified by the domain to specify what is unfragmented and why continuity matters.
