What is the difference between file compression and decompression?

What is decompression and how does it work?

  • Decompression generates an exact replica ofthe original object. Text compression is a good example of lossless compression. The repetitive nature of text, sound and graphic images allows replacement of repeated strings of characters or bits by codes.

What are compcompression algorithms?

  • Compression algorithms, in general, aim to convert some source data at the compression end into a compressed message, and to convert it back from the compressed message at the decompression end. This requires making certain assumptions about the source before the conversion takes place.

What is decompression (altitude)?

  • Decompression (altitude). the reduction of pressure and the related physiological effects due to increase in altitude or other equivalent reduction of ambient pressure below normal atmospheric pressure Uncontrolled decompression, catastrophic reduction of pressure in accidents involving pressure vessels such as aircraft
