Codec

A codec is a technology used to compress and decompress digital audio or video files, making them easier to store and transmit. Think of it as a specialized tool that reduces the file size without significantly losing quality, allowing for efficient streaming or storage. When you play the file, the codec decompresses it so you can view or listen to it normally. Popular codecs include MP3 for music and H.264 for videos. Essentially, codecs help balance quality and file size, ensuring smooth playback and efficient use of bandwidth.
