Description. "FreeSWITCH is an open source telephony platform designed to facilitate the creation of voice and chat driven products scaling from a soft-phone up to a soft-switch. It can be used as a simple switching engine, a PBX, a media gateway or a media server to host IVR applications using simple scripts or XML to control the callflow.

From Wikipedia's Distributed Computing article: "Distributed computing is a method of computer processing in which different parts of a program run simultaneously on two or more computers that are communicating with each other over a network. Distributed computing is a type of segmented or parallel computing, but the latter term is most commonly us...
Early, significant example: Seti@Home
The Seti@Home is one of the earliest distributed computing public project, which involved letting any user participate in the analysis of sound (high wavelenght, radio signals) coming from space (captured using the Arecibo Radio Observatory) in hope of discovering Alien life evidence. Since the project was lacking results (and still does), computing budgets were cut down; using grid computing let the research go on. A small software application did download samples, perform Fast Fourier Trans...
Concurrent computing is the fact to be able to achieve a task on multiple computing cores. Not any task can be easily multi-threaded. Multiple scale hardware systems are using multiple processors.
Distributed computing is said to achieve better overall energy efficiency than centralized supercomputing. Processors such as the Cell are extremely power sparing.
Ronja (Reasonable Optical Near Joint Access) is an User Controlled Technology (like Free Software) project of optical point-to-point data link. The device has 1.4km range and has stable 10Mbps full duplex data rate. Ronja is an optoelectronic device you can mount on your house and connect your PC, home or office network with other networks.
Switched point-to-point topologies are the basic model of conventional telephony. The value of a permanent point-to-point network is the value of guaranteed, or nearly so, communications between the two endpoints. The value of an on-demand point-to-point connection is proportional to the number of potential pairs of subscribers, and has been ...
Different applications of P2P networks enable users to share the computation power (distributed systems), data (file-sharing), and bandwidth (using many nodes for transferring data). P2P uses an individual's computer power and resources, instead of powerful centralized servers. The shared resources guarantee high availability among peers."
"Nick Carr’s forthcoming (January 2008) book, “The Big Switch: Our New Digital Destiny.” He makes a clear case that computing resources distributed via vast grids will transform economics, business and culture in the 21st century just as electric utilities did in the last century."
Origin of the term According to Kleiner and Gottlieb, the term "Counterantidisintermediation" was coined by Lief Ryge (@wiretapped).This implies "no servers, no admins!" Discussion Dmytri Kleiner: "On her blog, Wendy M. Grossman writes: "Disintermediation” was ...
