Media refers to the tools used to store and deliver information or data. The term media can refer to advertising, digital media, electronic media, hypermedia, mass media and multimedia, among many others. Digital media is an electronic medium where data is stored in digital form. It refers to the technical aspect of the storage and transmission of information, or to the end product consumed by a user, such as digital video, digital art or virtual reality.
Transformation of an analog signal to digital information through an analog-to-digital converter is called sampling. The majority of digital media is based on translating analog signals to digital data and vice versa. Digital media can be processed in a number of ways using standard computer hardware and software, where the performance is critical in high-performance digital hardware such as an application-specific integrated circuit (ASIC). The processing process involves editing, content creation and filtering. Electronic media use electronics or electro-mechanical energy to enable end users to access content. This is different from static media, which is often accessed by end users in printed form. Broadcasting is the distribution of audio and video content to a dispersed audience via radio, television, or other methods. Receiving parties may include the general public or a relatively large subset thereof. Electronic broadcasting includes telephone broadcasting, radio broadcasting, television broadcasting, cable radio, satellite television and webcasting.
