Codename
A code name, call sign or cryptonym is a Code word (figure of speech), code word or name used, sometimes clandestinely, to refer to another name, word, project, or person. Code names are often used for military purposes, or in espionage. They may also be used in industrial espionage, industrial counter-espionage to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names. Military origins During First World War, World War I, names common to the Allies of World War I, Allies referring to nations, cities, geographical features, military units, military operations, diplomatic meetings, places, and individual persons were agreed upon, adapting pre-war naming procedures in use by the governments concerned. In the British case n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Media DRM
Windows Media DRM or WMDRM, is a Digital Rights Management service for the Windows Media platform. It is designed to provide delivery of audio or video content over an IP network to a PC or other playback device in such a way that the distributor can control how that content is used. WMDRM includes the following components: * Windows Media Rights Manager (WMRM) SDK for packaging content and issuing licenses * Windows Media Format SDK (WMF SDK) for building Windows applications which support DRM and the Windows Media format * Windows Media DRM for Portable Devices (WMDRM-PD) for supporting offline playback on portable devices (Janus) * Windows Media DRM for Network Devices (WMDRM-ND) for streaming protected content to devices attached to a home network (Cardea) Windows Media DRM was replaced in Windows 10 Anniversary Update in favor of Microsoft PlayReady. How it works In May 2007 Microsoft published the network protocol behind its license acquisition mechanism. According to the ...

Computer Networking
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications protocols ...

Electronic Device
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small el ...

Janus (DRM)
Janus was the codename of a version of Windows Media DRM primarily for portable devices, whose marketing name was Windows Media DRM for Portable Devices (or in short form WMDRM-PD). It was introduced by Microsoft in 2004 for use on portable media devices which store and access content offline. Napster To Go was the first online music store to require the Janus technology. Supporting Janus often implies that the device also makes use of Media Transfer Protocol (MTP). Janus initially required supporting devices to ''not'' support non-Microsoft audio formats such as Ogg Vorbis, but this requirement was later removed. Characteristics To support Janus, devices must support: * Secure time * License storage for content items * Meters All of these are supported by way of challenge–response authentication commands. Stores that required Janus on portable devices Devices that used Janus * Most BlackBerry OS devices * Audiovox SMT 5600 smartphone * Toshiba Gigabeat S * Cowon iAudio X ...

Portable Electronics
Mobile computing is human–computer interaction in which a computer is expected to be transported during normal usage, which allows for the transmission of data, voice, and video. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats, and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications. Main principles * Portability: Devices/nodes connected within the mobile computing system should facilitate mobility. These devices may have limited device capabilities and limited power supply but should have a sufficient processing capability and physical portability to operate in a movable environment. * Connectivity: This defines the quality of service (QoS) of the network connectivity. In a mobile computing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
