Codec

Software that encodes or decodes digital audiovisual material, usually for storage or transmission in a compressed format. For example, the MP3 format compresses audio data and requires the MP3 codec (usually available by default in audio programs) to be played on a computer. Codecs can be downloaded or purchased and installed as plug-ins for most applications to enhance the software's multimedia capabilities. See also compression.

The codec compresses the information so that it can be sent over the network much faster. It also decompresses the information received over the network.
