Fragmentation Definition and Examples

Allogamy, internal fertilization, external fertilization, and autogamy are some of the types of sexual reproduction. This can reduce system performance and make it more difficult to access the file. It is generally best to defragment your hard disc on a regular basis to avoid fragmentation, which is a process that rearranges the blocks of data on the disc so that files are stored in contiguous blocks and can be accessed more quickly. Fragmentation in computers involves storing a single file in several different locations on a hard drive or other storage devices. This often occurs when individuals create, move, make changes, or delete files.

  1. These fragments grow and mature into a whole new generation with identical characteristics to their parents.
  2. The process of fragmentation is one of the most important mechanisms that mostly occur in a multicellular organism (i.e. the organism that is made up of more than a single cell).
  3. Not only does the metal have to be acquired but larger items, such as electronic systems, must also be assembled.
  4. (Ref. 2) In fragmentation, reproduction occurs via the breakage of the parent organism into various fragments that have the ability to grow identical to their parents.
  5. If additional pressure comes along, for instance, a sudden shift in the environment or habitat, the species could struggle even more and eventually could be eliminated and be extinct.

Fragmentation was made possible by improved technology and globalization. Bryophytes (nonvascular plants) are a plant group characterized by lacking vascular tissues. These groups of plants require external water, usually in the form of dew or rain.

The memory allocation scheme determines the fragmentation circumstances. These regions of memory become fragmented when the process loads and unloads from it, making it unusable for incoming processes. In English grammar, a fragment is a group of words that begins with a capital letter and ends with a period, question mark, or exclamation point but is grammatically incomplete. Also known as a sentence fragment, a verbless sentence, and a minor sentence. Though in traditional grammar fragments are usually treated as grammatical errors (or as errors in punctuation), they are sometimes used by professional writers to create emphasis or other stylistic effects.

SSDs allow a finite number of writes (i.e., putting information on the drive). Each and every time a defrag is run on a hard drive, it has to move the files from one location to another, each time writing the file to a new location. This means the SSD would endure constant writing, over and over again, as the defrag process progresses. Defragging is pretty straightforward and all of those tools have similar interfaces.

Asexual reproduction is carried out by a single parent and due to this only its traits, genes and characteristics will be passed on to the new generation. Without much genetic diversity, the next generation tends to be very identical to each other Conversely, in sexual reproduction, two genes from both parents are mixed. The airline industry is one that experienced a great deal of fragmentation. Not only does the metal have to be acquired but larger items, such as electronic systems, must also be assembled. Companies often source these materials in addition to labor in countries where they are cheaper.

What Is a Sentence Fragment in Writing?

When a new file is written, or when an existing file is extended, the operating system puts the new data in new non-contiguous data blocks to fit into the available holes. The new data blocks are necessarily scattered, slowing access due to seek time and rotational latency of the read/write head, and incurring additional overhead to manage additional locations. External fragmentation occurs when a storage medium, such as a hard disc or solid-state drive, has many small blocks of free space scattered throughout it.

Should I Defrag My Solid State Hard Drive?

Product quality may also suffer because of the use of cheaper labor and materials. Going abroad to produce goods can also lead to this problem since laws and regulations vary in different countries. For example, some countries may use items like lead paint in the production java developer job description template of their goods and services while others no longer use them. The term fragmentation refers to a supply chain that is broken up into different parts. Companies spread the production process across different suppliers and manufacturers when they fragment.

From your perspective, this is all happening in one place, but in reality, at least physically on the drive, this is often not the case. Habitat fragmentation takes place when large areas of habitable land are broken up and segmented or destroyed. It is most often related to land development by humans and natural forces (land erosion, climate change, natural disasters). In 2022, supply chains were affected by the COVID-19 pandemic as consumers saw shortages of products on shelves and price increases for those products.

Performance degradation

The result is that, although free storage is available, it is effectively unusable because it is divided into pieces that are too small individually to satisfy the demands of the application. The term “external” refers to the fact that the unusable storage is outside the allocated regions. Apart from this molecular aspect of the use of fragmentation, the term is also used to describe another cellular process wherein cellular parts undergo fragmentation. Apoptosis is the process in which the programmed destruction of cells occurs and it is achieved by a very organized sequence of morphological changes. Moreover, the morphological changes are characterized by cellular and nuclear shrinkage, chromatin fragmentation and condensation, the formation of apoptotic bodies, and the process of phagocytosis of all the available neighboring cells.

Fragments are simply pieces of files that aren’t placed next to each other on the drive. That might be kind of strange to think about, and nothing you would ever notice, but it’s true. While segmentation is a technique that includes breaking a process up into several modules or sections, fragmentation is a situation in which memory chunks are left unused. An industry that is far too fragmented can often be problematic as outlets may find it difficult to reach their target audiences. These entities are often in different countries, especially where labor is plentiful and inexpensive.

Outsourcing the production and manufacturing process takes jobs away from domestic workers, which means an increase in unemployment in the company’s home nation. Free trade agreements may often provide countries with duty-free access to labor and materials. For instance, the USMCA and its predecessor, NAFTA, set this up between the U.S., Canada, and Mexico. These examples are programmatically compiled from various online sources to illustrate current usage of the word ‘fragmentation.’ Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors.
