What is worm?

What Does worm Mean

There are different theories about the etymological origin of the term worm that we are now dealing with. However, there are two theories that are the most relevant. On the one hand, there is the one that indicates that it could derive from a pre-Roman term such as "gusarapo". On the other, there is the one that establishes that it comes from Latin, specifically from "cossus", which, in turn, emanates from the Sanskrit "kusu", which can be translated as "worm".

A worm is an invertebrate animal characterized by its soft body without feet or appendages. The term is used as a generic name for various metazoan species (they have numerous differentiated cells that are grouped into apparatus, organs and tissues) that can be parasitic or have free life.
Other of the most significant characteristics of worms are that they have cutaneous respiration, that is, through the skin and that their bodies usually have hairs or bristles that cover them.

The worms are elongated and can belong to the phyla of nematodes , annelids or flatworms , among others.
Nematodes, in the first place, are identified because they have a cylindrical shape and because they are quite long. To all this we must add that they do not have visible segments. Among the worms that are included in this group is, for example, Trichina.
Annelids, secondly, are worms that are characterized because their body is shaped and divided into clearly visible rings and because they tend to grow and live in very humid spaces. Among the most significant of this type are leeches and earthworms.
The flatworms, thirdly, we have to establish that they are the worms that have the peculiarity of presenting a flattened shape. Likewise, it is highlighted the fact that in order to survive it is necessary for them to choose to parasitize. Among those that are included in this group we can highlight the tapeworm.
The worms and leeches , for example, are among the best known worms.
The long, cylindrical, soft-bodied larvae of insects are also called maggots . These worms can be cresas (the larvae of flies) or caterpillars (the larvae of butterflies).
In the field of computing , a malicious program ( malware ) that has the ability to duplicate itself is known as a worm . Called worms in English, worms usually install themselves in sectors of the operating system that are invisible to users, from where they spread without the need for a human intervention.
Housed in memory, the worm does not modify files, unlike viruses . In general, its main damage is the consumption of bandwidth to cause problems in a network.

Finally, in colloquial language, a mean individual is called a worm who is despicable because of his behavior or attitudes: “Get away from Javier! The only thing that worm knows how to do is harm ” , “ A worm cheated my grandmother and stole all her savings ” , “ I work for a worm that exploits and mistreats me: I would love to find another job ” .
