What is decompress?

What Does decompress Mean

Decompress is a verb that refers to minimizing or eliminating compression in a closed place or in a body. The process and result of decompressing is called decompression.

Compression is the pressure to which a body is subjected by the action of opposing forces that develop a tendency to reduce its volume. The action of decompressing involves the opposite procedure, since it implies reducing said compression.
The interior of an airplane, for example, is pressurized : it has a system to preserve normal atmospheric pressure beyond the outside pressure that is registered by altitude. A failure, however, can decompress the cabin. It is called uncontrolled decompression to unplanned reduction in pressure of a given system .

The idea of ​​decompressing is also used in a symbolic sense with respect to social pressure . When people are angry or upset about something, they can push for an answer or solution. Such pressure can even lead to episodes of violence. That is why it is important that the authorities or those responsible for this tension take care of decompressing the situation. Let us suppose that, in a city, there is a massive march demanding greater security. Faced with this demonstration, the government tries to decompress by announcing that it will increase the number of police in the streets and that it will present a bill to increase the penalties applied to criminals.
In computing , files can be compressed to smaller size or weight by removing bits . To open an unzipped file, it must first be unzipped.
Thanks to compression , it is possible to store and transmit large files in a more agile way, either taking up less disk space, consuming less data when transferring over a network or speeding up the process. Broadly speaking, we can generalize that text files are the ones that occupy the least space and, therefore, the ones that are not usually compressed; Of course, it is also possible to do it, and in fact it does not involve great complications.
The types of files that are most often compressed are photographic, audio, and movie; the latter are a fusion of the first two types, since they are made up of a large number of images combined with sound files. In order to save money on storage media, companies are also turning to compression to distribute their products such as music discs and movies; As mentioned before, the respective players must unzip the files before reading them.

Of course, this process can be carried out through several methods , each with its own pros and cons. First of all, we must understand that the ideal of compression is to make a file occupy less space without losing its essence , so that it is possible to recover it when decompressing it.
Simply put, there are two possible ways to compress a file: with and without data loss . To remove data considered unnecessary or to make it take up less space, various mathematical methods are applied (in more technical terms, we are talking about algorithms , that is, series of steps that are repeated as in a recipe).
Decompressing a heavy file at runtime, that is to say at the moment in which it must be reproduced, requires a great deal of processing power. This is very common today, and for this the components of devices such as video game consoles and blu-ray players are custom made, thinking about this function so that it can be carried out without the need to run a separate program. .
