In the mid-20th century, a codec was a device that coded analog signals into digital form using pulse-code modulation (PCM). Later, the name was also applied to software for converting between digital signal formats, including compandingfunctions.
An audio codec converts analog audio signals into digital signals for transmission or encodes them for storage. A receiving device converts the digital signals back to analog form using an audio decoder for playback. An example of this is the codecs used in the sound cards of personal computers. A video codecaccomplishes the same task for video sig...
In addition to encoding a signal, a codec may also compress the data to reduce transmission bandwidth or storage space. Compression codecs are classified primarily into lossy codecs and losslesscodecs. Lossless codecs are often used for archiving data in compressed form while retaining all information present in the original stream. If preserving t...
Two principal techniques are used in codecs, pulse-code modulation and delta modulation. Codecs are often designed to emphasize certain aspects of the media to be encoded. For example, a digital video (using a DVcodec) of a sports event needs to encode motion well but not necessarily exact colors, while a video of an art exhibit needs to encode col...
Fake codecs are used when an online user takes a type of codec and installs viruses and other malware into whatever data is being compressed and uses it as a disguise. This disguise appears as a codec download through a pop-up alert or ad. When a user goes to click or download that codec, the malware is then installed on the computer. Once a fake c...

From Wikipedia, "a codec is a device or computer program capable of encoding and/or decoding a digital data stream or signal." In general, codecs are utilized by multimedia applications to encode or decode audio or video streams. In order to play encoded streams, users must ensure an appropriate codec is installed.
