Short for single instruction, multiple data. A type of parallel computing architecture that is classified under Flynn’s taxonomy. A single computer instruction perform the same identical action (retrieve, calculate, or store) simultaneously on two or more pieces of data (Charles Belov, 1997). * Typically this consists of many simple processors, each with a local memory in which it keeps the data which it will work on. Each processor simultaneously performs the same instruction on its local data progressing through the instructions in lock-step, with the instructions issued by the controller processor. The processors can communicate with each other in order to perform shifts and other array operations. [* Source: EPCC]
)Acronym for single in-line memory module, a small circuit board that can hold a group of memory chips. Typically, SIMMs hold up to eight (on Macintoshes) or nine (on PCs) RAM chips. On PCs, the ninth chip is often used for parity error checking. Unlike memory chips, SIMMs are measured in bytes rather than bits. […]
Short for Session Initiation Protocol (SIP) for Instant Messaging and Presence Leveraging Extensions, an application of the SIP protocol for server-to-server and client-to-server interoperability in instant messaging. SIMPLE is a step in bringing standardization to instant messaging.
A high level programming language designed specifically for use in simulation environments for building large scale simulation and modeling applications. The syntax of SIMSCRIPT is English-like allowing for long identifiers, and the capability for users to tailor the appearance of the source code. SIMSCRIPT was first produced by Harry Markowitz of Rand Corp in 1963.
(pronounced “shock”) Short for Semantically Interlinked Online Communities SIOC is a project that proposes a method for interconnecting blogs, forums and mailing lists to each other on the Semantic Web. SIOC started with the development of the SIOC core ontology, which is used to describe the domain of online communities and what they consist of […]
(1) Short for Session Initiation Protocol, it is an application-layer control protocol; a signaling protocol for Internet Telephony. SIP can establish sessions for features such as audio/videoconferencing, interactive gaming, and call forwarding to be deployed over IP networks, thus enabling service providers to integrate basic IP telephony services with Web, e-mail, and chat services.
