IPA: /ˈkoʊdɛk/

The video codec compressed the file size without losing quality.
Codec → It is formed from "code" (from Latin *codex*, meaning a book or manuscript) and "-ec" (a suffix used in technology to denote a specific type or category). The word "codec" refers to a device or program that encodes or decodes a data stream or signal, essentially a tool for handling coded information.
Think of a 'code' as a way to represent information, and the '-ec' helps you remember that a codec is a tool for encoding and decoding that information.
