codec

This term is a portmanteau of coder and decoder, reflecting the dual nature of the technology. It is primarily used in technical contexts involving digital media, such as audio and video processing, where the goal is to reduce file size for storage or transmission without losing significant quality.

In professional settings, the word is used as a neutral technical descriptor. Users often distinguish between lossy codecs, which discard some data to achieve higher compression, and lossless codecs, which preserve every bit of the original information.
