Compression is a process that is based on subjecting a body to the action of two opposing forces, in such a way that its volume is reduced.
Compression , from Latin compressĭo , is the action and effect of compressing . This verb refers to narrowing, squeezing, oppressing or reducing to a lower volume . For example: “The suitcases entered the trunk under compression so we are going to have to travel carefully” , “The doctor recommended that I use wider pants since the compression of the stomach is not good” , “The compression of the file has not yet has ended.”
Compression can be a physical or mechanical process that consists of subjecting a body to the action of two opposing forces so that its volume decreases. The result of these tensions is known as compressive stress .
A pillow filled with foam rubber can be compressed if we exert force with both hands to shrink it. Due to its characteristics, once we stop using the force, the cushion will recover its usual shape and size. However, if when it is compressed we place it in a small space that prevents it from growing again or we tie it up, we will have managed to reduce its volume.
spinal cord compression
Within the field of medicine, we would have to highlight the existence of the term spinal compression . It is a serious health problem for the neurological system and results in consequences such as loss of sensitivity in the body, paralysis of the body or a complete lack of control of the sphincters.
Pain is the main symptom of this ailment that urgently needs to be diagnosed, since it is the way it can be stopped or eliminated. It must also be emphasized that people who suffer from it must undergo treatment that, based on the advanced stage of the disease, may consist of surgery, medications such as corticosteroids or even oncological and radiotherapy treatment.
Cancer is what usually gives rise to the aforementioned spinal cord compression, which was discovered in 1925 and currently affects 2% of the population that suffers from it. Specifically, it most commonly appears in adults between 40 and 60 years old and who are facing prostate or breast cancer.
In the field of computing, data compression is used to refer to the reduction in the size or weight of a digital file.
Nerve root problem
Likewise, within this sector, we would have to highlight the existence of what is known as nerve compression. As its name indicates, it is the compression of a nerve root and is basically identified because it results in overwhelming pain.
The extremities, such as the hands, are the ones that can usually be most affected by this type of health problem.
data compression
In the field of computing , data compression consists of reducing the weight of a digital file by reducing the volume of processable data. This means that the file in question, after compression, will take up less space.
Compression is carried out based on three types of information: basic (which must be transmitted so that the signal can be reconstructed), redundant (repetitive information) or irrelevant (its elimination does not affect the content). The compression typology, therefore, can be truly lossless, subjectively lossless, or subjectively lossy.
