It is called fragmentation to the act and the result of fragmenting : make something divide into fragments (parts, pieces). According to the context, the notion has different uses.
Fragmentation can be a asexual division mechanism . In this case, an individual is divided into different parts, each with the ability to develop the reconstruction of a complete organism. Such reconstruction can take place before or after the cleavage .
When reconstruction takes place before fragmentation, we talk about paratomy . Certain worms reproduce in this way. However, if the reconstruction is done after fragmentation, the process is known as architomy , as worms can reproduce land And the starfish.
Fragmentation reproduction also appears in the vegetables . Yes one person decides to propagate a plant by stakes or layers What it does is fragment it (taking branches or portions of them) to produce new roots and obtain other individuals.
In the field of ecology , the idea of habitat fragmentation It refers to the emergence of discontinuities in areas that previously had continuous vegetation. With fragmentation, the habitat becomes a set of fragments that appear isolated from each other and disconnected.
The fragmentation of habitats, which can be generated by natural mechanisms (such as wind action) or by human intervention, threatens the biodiversity , since the original flow of energy and matter is modified.
It is known by the name of fragmentation pump , cluster or of cluster to a directed or free fall that can be launched from air, sea or land. The characteristic of this bomb What gave it its name is that when it opens it releases many, but smaller ones, which can be used with various objectives: to cause harm or death to a large number of people indiscriminately; cause fires; cross armored vehicles.
The origin of the fragmentation bomb has not been fully defined: while some researchers say it was created in Nazi Germany, others point to a Chilean businessman named Carlos Cardoen , who manufactured a fragmentation bomb class during the 70s. The truth is that its presence in the field of cinema and video games is very wide, since it is ideal to cause explosions spectacular; Unfortunately, its almost "humorous" representation in the entertainment world has little to do with the consequences of its use in reality.
In the field of computing Finally, fragmentation is called blank space generation that cannot be used on disk. This occurs when files are stored in fragments that are not contiguous. Fragmentation makes access to such files inefficient.
As a counterpart to the fragmentation, the defragmentation , a process that aims to accommodate files within storage memory so that all parts are contiguous and more efficient to use. Fragmentation occurs "naturally", through the daily use of files: with the continuous writing and deletion of files on the hard drive, it is normal that their fragments are not stored together and this makes access to them slower .
It is important to note that solid state disks (known simply by his acronym SSD ) work in a very different way than hard drives , and do not produce file fragmentation. In fact, if we run a defragmentation tool in an SSD we put its longevity at risk, since its technology allows a much smaller number of readings and writes than traditional disks.
