A compressor is a machine that, by appealing to an increase in pressure, manages to move a compressible fluid.
Compressor is something that compresses (squeezes, presses, reduces to a lower volume). The term, which comes from the Latin compressor , is used to name a machine that, through an increase in pressure , manages to displace compressible fluids, such as gases .
The compressor not only displaces fluids, but also modifies the density and temperature of the compressible fluid. Compressors are used in various areas, such as air conditioning equipment, refrigerators, turbojets and in certain electrical generation systems.
Types of compressors
According to the method of energy exchange, compressors can be divided into different types, such as reciprocating compressors (which open and close valves to suck or compress the gas), rotary compressors (with rotating screws) or rotodynamic compressors (which use to an impeller with blades), among others.
In addition to everything stated above, we would also have to highlight the existence of what is known as a compressor cylinder . We can say that this is a roller that is used with the clear objective of being able to carry out what would be not only the leveling of the earth but also being able to tighten it as desired.
In computing, a compressor allows you to reduce the size of a file.
The notion in computing
A compressor, on the other hand, is the computer program ( software ) that allows you to reduce the size of a digital file . To perform compression , these programs look for redundancies in the files and eliminate them, allowing information to be deleted to reduce weight but without loss of quality.
There are many compressors that are used in the field of computing to be able, for example, to send a file with photographs to a person without it weighing too much and without the relevant email platforms encountering the fact that they are not capable to send an email with such volume.
However, among the most common and frequent compressors used is WinRAR, which has the following hallmarks:
- It is used both to compress and decompress.
- It is developed by RarLab.
- It gives the possibility of compressing a wide variety of files and documents.
- It has the advantages that it is very easy to use and that it performs its functions very quickly.
- In the same way, we must not forget that another of the most significant hallmarks of WinRAR is that it is more powerful than other of its competitors on the market.
- It is very secure and also has the facility to even work with files up to 9000 PetaBytes.
Its economical price, its versatility and its usefulness for carrying out all types of backups are other of the most significant features of this compressor.
audio compressor
An audio compressor , finally, is an electronic sound processor that reduces the dynamic range of a signal. These compressors work by attenuating the electrical signal by a certain amount of decibels to protect certain equipment from possible signal peaks or to hide the error of a saturated sound.
These compressors are used in concerts (with direct sound) and in music recordings. If a bassist hits the strings with a finger at a live show, the effect generated could damage the amplifier if a compressor is not used.
