Streamingvignette|Une configuration de pour la télédiffusion. Le (du verbe anglais transitif , « transférer en mode continu »), flux, lecture en continu, lecture en transit, diffusion en continu ou diffusion en mode continu, est un procédé de diffusion d'un flux audio ou vidéo en « direct » ou en léger différé. Très utilisé sur Internet et sur les réseaux de téléphonie mobile, le permet la lecture d'un flux audio ou vidéo (cas de la vidéo à la demande) à mesure qu'il est diffusé.
Wireless network interface controllerA wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi or Bluetooth, rather than a wired network, such as a Token Ring or Ethernet. A WNIC, just like other NICs, works on the layers 1 and 2 of the OSI model and uses an antenna to communicate via radio waves. A wireless network interface controller may be implemented as an expansion card and connected using PCI bus or PCIe bus, or connected via USB, PC Card, ExpressCard, Mini PCIe or M.
2G2G is a short notation for second-generation cellular network, a group of technology standards employed for cellular networks. 2G was commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991. After 2G was launched, the previous mobile wireless network systems were retroactively dubbed 1G. While radio signals on 1G networks are analog, radio signals on 2G networks are digital, though both systems use digital signaling to connect cellular radio towers to the rest of the mobile network system.
Absolute rotationIn physics, the concept of absolute rotation—rotation independent of any external reference—is a topic of debate about relativity, cosmology, and the nature of physical laws. For the concept of absolute rotation to be scientifically meaningful, it must be measurable. In other words, can an observer distinguish between the rotation of an observed object and their own rotation? Newton suggested two experiments to resolve this problem.
