Fragmentation can refer to different things depending on the context. Here are some definitions and examples of fragmentation:

  • Fragmentation in reproduction: Fragmentation is a form of asexual reproduction or cloning, where an organism is split into fragments upon maturation and the split part becomes a new individual. This process is observed in multicellular or colonial organisms such as spirogyra, filamentous cyanobacteria, molds, lichens, sponges, acoel flatworms, some annelid worms, sea stars, and some plants).

  • Fragmentation in computing: Fragmentation is a phenomenon in which storage space, main storage or secondary storage, is used inefficiently, reducing capacity or performance and often both. This can occur in different ways, such as external fragmentation, where free space is broken into small pieces, or internal fragmentation, where allocated space is larger than necessary. Fragmentation can cause performance degradation and even system failure).

  • Other uses of fragmentation: Fragmentation can also refer to the breaking into smaller parts, the disintegration, collapse, or breakdown of norms of thought, behavior, or social relationship. In biology, it may refer to a step in certain cellular activities, such as apoptosis and DNA cloning. In addition, fragmentation can be seen in various algae.

In summary, fragmentation can refer to a process of asexual reproduction in some organisms, a phenomenon in computing that can cause performance degradation and system failure, or the breaking into smaller parts or the disintegration of norms of thought, behavior, or social relationship.
