compression ratio

compression ratio
Danh từ
Số nhiều: compression ratios

This term is a technical specification used across two distinct fields: mechanical engineering and data science. In thermodynamics, it describes the physical pressure increase within a combustion chamber, where a higher ratio typically correlates with greater efficiency but increases the risk of engine knocking.

In computing, the term refers to the efficiency of a data encoding algorithm. It is expressed as a proportion (e.g., 10:1), indicating how much the original file size has been reduced. While the mechanical sense refers to physical volume, the digital sense refers to binary data volume.
