Cache Serveur. Serveur. Protocole SIP - Tout savoir sur le protocole SIP. Difference between Speed Class, UHS Speed Class, and Speed Ratings (performance) for SD/SDHC/SDXC cards. Difference between Speed Class, UHS Speed Class, and Speed Ratings (performance) for SD/SDHC/SDXC cards What is the difference between Speed Class and Speed Ratings for SDTM/SDHCTM cards? The speed rating measures maximum transfer speed for reading and writing images to and from a memory card, expressed as megabytes per second. However, video doesn't need as big a data pipe because the video format is a smaller "fixed stream" that uses only a portion of the data pipe.

Cache? Crack the code for the code. BitTorrent. Programmer Bram Cohen, a former University at Buffalo graduate student in Computer Science,[4] designed the protocol in April 2001 and released the first available version on July 2, 2001,[5] and the final version in 2008.[6] BitTorrent clients are available for a variety of computing platforms and operating systems including an official client released by Bittorrent, Inc.


As of 2009, BitTorrent reportedly had about the same number of active users online as viewers of YouTube and Facebook combined.[7][8] As of January 2012[update], BitTorrent is utilized by 150 million active users (according to BitTorrent, Inc.). Based on this figure, the total number of monthly BitTorrent users can be estimated at more than a quarter of a billion.[9] Description[edit] The middle computer is acting as a seed to provide a file to the other computers which act as peers. Digital Living Network Alliance. The Digital Living Network Alliance (DLNA) is a nonprofit collaborative trade organization established by Sony in June 2003, that is responsible for defining interoperability guidelines to enable sharing of digital media between multimedia devices.[3] These guidelines are built upon existing public standards, but the guidelines themselves are private (available for a fee).

These guidelines specify a set of restricted ways of using the standards to achieve interoperability and include almost no free audio formats and only the most common (free or otherwise) video formats, meaning that DLNA servers generally have to support transcoding in order to produce a useful service.[4] Detexify LaTeX handwritten symbol recognition.

Started in May 2002 as an alternative to eDonkey2000, eMule now connects to both the eDonkey network and the Kad network. The distinguishing features of eMule are the direct exchange of sources between client nodes, fast recovery of corrupted downloads, and the use of a credit system to reward frequent uploaders. Géolocalisation. HDMI. HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transferring uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device.[1] HDMI is a digital replacement for analog video standards.


HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed, uncompressed, and LPCM audio, auxiliary data, and implementations of the VESA EDID.[2][3] CEA-861 signals carried by HDMI are electrically compatible with the CEA-861 signals used by the digital visual interface (DVI). Several versions of HDMI have been developed and deployed since initial release of the technology but all use the same cable and connector. History[edit] Specifications[edit] Audio/video[edit] Internet protocol suite.

The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks.

Internet protocol suite

It is commonly known as TCP/IP, because its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP), were the first networking protocols defined in this standard. Often also called the Internet model, it was originally also known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense.

TCP/IP provides end-to-end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination. Localhost. In computer networking, localhost means this computer.


It is a hostname that the computer's software and users may employ to access the computer's own network services via its loopback network interface. Using the loopback interface bypasses local network interface hardware. The local loopback mechanism is useful for testing software during development independent of any networking configurations. If a computer has been configured to provide a website, directing its web browser to may display its home page. The name is also a reserved top-level domain name (cf. .localhost), set aside to avoid confusion with the narrower definition as a hostname.[1] The IETF standards restrict domain name registrars to assign the name in their normal registration procedures, such as for second-level domains, e.g.,

Lulz. Napster. Later systems successfully followed and elaborated on Napster's file-copying methods, including Gnutella, Freenet, Bit Torrent and many others.


Some systems, like LimeWire, Grokster, Madster and the original eDonkey network, were shut down or altered under similar circumstances. Origin[edit] Napster was co-founded by Shawn Fanning, John Fanning, and Sean Parker.[2][3][4][5][6][7][8][9] Initially, Napster was envisioned as an independent peer-to-peer file sharing service. The service operated between June 1999 and July 2001.[10] Its technology allowed people to easily share their MP3 files with other participants.[11] Although the original service was shut down by court order, the Napster brand survived after the company's assets were liquidated and purchased by other companies through bankruptcy proceedings.[12] History[edit]

OpenVPN. OpenVPN has been ported and embedded to several systems. For example, DD-WRT has the OpenVPN server function. SoftEther VPN, a multi-protocol VPN server, has an implementation of OpenVPN protocol. Architecture[edit] Encryption[edit] Open-source software. Open-source software (OSS) is computer software with its source code made available and licensed with a license in which the copyright holder provides the rights to study, change and distribute the software to anyone and for any purpose.[1] Open-source software is very often developed in a public, collaborative manner.

Open-source software is the most prominent example of open-source development and often compared to (technically defined) user-generated content or (legally defined) open-content movements.[2] A report by the Standish Group (from 2008) states that adoption of open-source software models has resulted in savings of about $60 billion per year to consumers.[3][4] Definitions[edit] The Open Source Initiative's (OSI) definition is recognized[who?] As the standard or de facto definition. OpenSSL. History of the OpenSSL project[edit] The OpenSSL project was founded in 1998 to invent a free set of encryption tools for the code used on the Internet. As of 2014 two thirds of all webservers use it.

The OpenSSL project management team consists of 4 Europeans. The entire group consists of 11 members, of which 10 are volunteers, with only one full-time employee, Stephen Henson, the lead developer. The project has a budget of less than $1 million a year and relies in part on donations. Peer-to-peer file sharing. Peer-to-peer file sharing is the distribution and sharing of digital documents and computer files using the technology of peer-to-peer (P2P) networking. P2P file sharing allows users to access media files such as books, music, movies, and games using a specialized P2P software program that searches for other connected computers on a P2P network and locates the desired content.[1] The nodes (peers) of such networks are end-user computer systems that are interconnected via the Internet.

Several factors contributed to the widespread adoption and facilitation of peer-to-peer file sharing. These included increasing Internet bandwidth, the widespread digitization of physical media, and the increasing capabilities of residential personal computers. Users were able to transfer either one or more files from one computer to another across the Internet through various file transfer systems and other file-sharing networks.[1] Post-WIMP. PolarSSL. Radio-frequency identification. Da Wikipedia, l'enciclopedia libera. SAN non è NAS letto al contrario. Di Roberto Mazzoni · 1 dicembre 2008 La creazione di una Storage Area Network comporta complessità che possono frenarne l’adozione specialmente in organizzazioni di piccole e medie dimensioni che non dispongono di personale qualificato al proprio interno e che hanno un budget di spesa IT risicato.

E’ difficile percepire di primo acchito le differenze esistenti tra una SAN e un più semplice sistema NAS (Network Attached Storage) che possiamo acquistare per poche centinaia di euro e che possiamo usare immediatamente dopo averlo collegato alla rete elettrica e alla rete locale. Eppure le differenze sono profonde e si traducono in benefici di business percepibili. Server-side language. SHA-2: le risposte alle sue domande  Trol (Internet) URL = Uniform resource locator. URN.
