An endec (encoder/decoder) is a agnate yet altered abstraction mainly acclimated for hardware. In the mid 20th century, a "codec" was accouterments that coded analog signals into Pulse-code accentuation (PCM) and decoded them back. Late in the aeon the name came to be activated to a chic of software for converting a part of agenda arresting formats, and including compander functions.
A modem is a abbreviating of modulator/demodulator (modem was alleged dataset by telcos) and converts agenda abstracts from computers to analog for buzz band transmission. On the accepting end the analog is adapted aback to digital. Codecs do the adverse (convert audio analog to agenda and again computer agenda complete aback to audio).
An audio codec converts analog audio signals into agenda signals for manual or storage. A accepting accessory again converts the agenda signals aback to analog application an audio decompressor, for playback. An archetype of this are the codecs acclimated in the complete cards of claimed computers. A video codec accomplishes the aforementioned assignment for video signals.
