Lecteur de disque optiquethumb|Lecteur de CD-ROM. Le lecteur de disque optique est un appareil électronique permettant de lire des disques optiques comme les disques compacts (ou CD) et DVD.

New mediaNew media are communication technologies that enable or enhance interaction between users as well as interaction between users and content. In the middle of the 1990s, the phrase "new media" became widely used as part of a sales pitch for the influx of interactive CD-ROMs for entertainment and education. The new media technologies, sometimes known as Web 2.0, include a wide range of web-related communication tools such as blogs, wikis, online social networking, virtual worlds, and other social media platforms.
Electronic mediaElectronic media are media that use electronics or electromechanical means for the audience to access the content. This is in contrast to static media (mainly print media), which today are most often created digitally, but do not require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and online content. Most new media are in the form of digital media.
