A codec is a device or software that encodes and decodes digital data. The term "codec" is a combination of "coder" and "decoder." Codecs are commonly used for compressing and decompressing audio and video files, enabling efficient storage and transmission. In the context of audio and video, a codec converts analog signals into digital formats (encoding) and the reverse process (decoding). This is crucial for streaming, editing, and playing multimedia content.
