Digital media can exist in several forms including text, audio, images, video, and animations. It is digitized through various methods like scanning text and images or using a CCD sensor to capture video frames. The digitized data is converted to binary numbers using analog to digital converters and encoders. This allows digital media to be manipulated, stored, and transmitted on computer networks and broadband systems. To be viewed or played, the digital media needs to go through a decoding and reconversion to analog process using a decoder and digital to analog converter. Common file formats for digital media include text documents, photos, movies and music files.
