AllJoyn. AllJoyn. AllJoyn is a system that allows devices to communicate with other devices around them.


A simple example would be a motion sensor letting a light bulb know no one is in the room it is lighting, so it can shut itself off. The AllJoyn software framework and core system services let compatible devices and applications find each other, communicate and collaborate across the boundaries of product category, platform, brand, and connection type. Target devices include those in the fields of Connected Home, Smart TV, Smart Audio, Broadband Gateways, and Automotive.[6] Qualcomm is working on providing OEM solutions. Currently, the communication layer (and thus hardware requirements) is limited to wi-fi.[7] Though the protocol started at Qualcomm, they have signed over the source code to the Linux Foundation. Technology[edit] The system uses the Client–server model to organize itself.

The system also has technology for audio streaming to multiple device sinks in a synchronized way.[15] APIs[edit] Hyperlink. Internet of Things, IoT. ACPI - Advanced Configuration and Power Interface. Advanced Configuration and Power Interface. In computing, the Advanced Configuration and Power Interface (ACPI) specification provides an open standard for device configuration and power management by the operating system.

Advanced Configuration and Power Interface

First released in December 1996, ACPI defines platform-independent interfaces for hardware discovery, configuration, power management and monitoring. Advanced Configuration and Power Interface. Da Wikipedia, l'enciclopedia libera.

Advanced Configuration and Power Interface

La specifica Advanced Configuration and Power Interface (ACPI) è uno standard industriale aperto reso disponibile per la prima volta nel dicembre 1996 e sviluppato da HP, Intel, Microsoft, Phoenix e Toshiba. Essa definisce interfacce comuni per il riconoscimento dell'hardware, la configurazione e la gestione energetica di scheda madre e periferiche. Secondo la sua specifica, "L'ACPI è l'elemento chiave nella configurazione e gestione energetica controllata dal Sistema Operativo (OSPM)".

L'ultima revisione della specifica ACPI è la 5.0, diffusa il 23 novembre 2011. What is ACPI? Webopedia. ADSL. Asymmetric digital subscriber line. VDSL. Very-high-bit-rate digital subscriber line. This VDSL modem used in Taiwan provides 4 Ethernet ports and an internal filter for voice-data separation.

Very-high-bit-rate digital subscriber line

Second-generation systems (VDSL2; ITU-T G.993.2 approved in February 2006) use frequencies of up to 30 MHz to provide data rates exceeding 100 Mbit/s simultaneously in both the upstream and downstream directions. The maximum available bit rate is achieved at a range of about 300 meters; performance degrades as the loop attenuation increases. Development[edit] The concept of VDSL was first published in 1991 through a joint Bellcore-Stanford research study. The study searched for potential successors to the then-prevalent HDSL and relatively new ADSL, which were both 1.5 Mbit/s. VDSL standards[edit] A VDSL connection uses up to seven frequency bands, so one can allocate the data rate between upstream and downstream differently depending on the service offering and spectrum regulations.

Application programming interface

Caratteristiche[modifica | modifica sorgente] Le API sono essenziali per i computer come gli standard elettrici lo sono per una casa. Chiunque può inserire la spina del tostapane nella presa a muro della sua casa o dal vicino perché entrambe le case sono conformi ad uno standard. Se non ci fosse una interfaccia standard, occorrerebbe avere una centrale elettrica per fare un toast. Public vs Private vs Internal APIs. This week saw Kin Lane post an interesting piece over at API evangelist on the Public v’s Private API distinction that drew a rather animated response from David Berlind at ProgrammableWeb.

Public vs Private vs Internal APIs

Both pieces make some interesting points, but they seem to talk past each other a little. Forgiving brevity for both, Kin’s point: “This is a reality that plays out in conversations between people who don’t fully understand the world of API management—aka the tech blogosphere. If it has an in front of the address, it is a public API—sorry. ASCII. Da Wikipedia, l'enciclopedia libera.

Assembly language. Assembly language is converted into executable machine code by a utility program referred to as an assembler.

Assembly language

The conversion process is referred to as assembly, or assembling the source code. Assembly time is the computational step where an assembler is run. Different. Machine code. Machine code or machine language is a set of instructions executed directly by a computer's central processing unit (CPU). Each instruction performs a very specific task, such as a load, a jump, or an ALU operation on a unit of data in a CPU register or memory. Every program directly executed by a CPU is made up of a series of such instructions. Numerical machine code (i.e., not assembly code) may be regarded as the lowest-level representation of a compiled or assembled computer program or as a primitive and hardware-dependent programming language. While it is possible to write programs directly in numerical machine code, it is tedious and error prone to manage individual bits and calculate numerical addresses and constants manually.

It is thus rarely done today, except for situations that require extreme optimization or debugging. Hyperlink. M, acronimi informatica.
