To be able to store large amounts of data, a huge amount of storage space is required. When the space is at some point full, a new storage space is usually made available. Mainly in the form of new hard drives, server systems or the like. But there is another way to store more data: data compression.<\/p>\n

\"Lossless<\/p>\n

Data compression works like a pillow you squeeze
\nFiguratively speaking, data compression works the same way as when you squeeze a pillow. Not all air is required between the pillowcase and the feathers. By squeezing the pillow, you compress it by removing the air (as much as you can); the pillow becomes smaller, that is, more compressed than before.<\/p>\n

It is similar with data compression. Here also items that are not absolutely necessary, in this case data, are removed and the storage space still required by the remaining data is reduced.<\/p>\n

\"Lossy<\/p>\n
