Digital media can exist in several forms including text, audio, images, video, and animations. It is represented using binary numbers and involves digitization through the use of technologies like scanners, cameras, and microphones. During digitization, analog signals are converted to digital data through processes like analog-to-digital conversion. This digital data can then be encoded, transmitted over computer networks and the internet, stored, manipulated, and played back on various devices through decoding and digital-to-analog conversion processes. Common file formats for different types of digital media include text documents, audio files, image files, and video files.
