Beowulf
Beowulf is an approach to building a supercomputer as a cluster of commodity off-the-shelf personal computers, interconnected with a local area network technology like Ethernet, and running programs written for parallel processing. The Beowulf idea is said to enable the average university computer science department or small research company to build its own small supercomputer that can operate in the gigaflop (billions of operations per second) range. Beowulf can be implemented with typical personal computers. It is easy to expand for increased performance.
BitTorrent
BitTorrent (often abbreviated to 'BT') is a protocol that allows you to download files quickly and efficiently. It is a peer to peer protocol, which means you download and upload to other people downloading the same file. BitTorrent is often used for distribution of large files or popular content as it is a cheap, fast, efficient way to distribute files to users like you.Using a server and several clients on a network, BitTorrent is clocked alongside two traditional protocols to determine which takes the least amount of time. From its inauspicious start in 2001, bittorrent has grown to one of the major forces on the internet. BitTorrent prevents tampered or broken files from being shared.
Cloud computing is the phrase used to describe different scenarios in which computing resource is delivered as a service over a network connection (usually, this is the internet).
Cloud computing is therefore a type of computing that relies on sharing a pool of physical and/or virtual resources, rather than deploying local or personal hardware and software. It is somewhat synonymous with the term ‘utility computing’ as users are able to tap into a supply of computing resource rather than manage the equipment needed to generate it themselves; much in the same way as a consumer tapping into the national electricity supply, instead of running their own generator.
Hyper Wiser
In virtualization technology, hypervisor is a software program that manages multiple operating systems (or multiple instances of the same operating system) on a single computer system. The hypervisor manages the system's processor, memory, and other resources to allocate what each operating system requires. The first hypervisors were introduced in the 1960s to allow for different operating systems on a single mainframe computer. However, its current popularity is largely due to Linux and Unix. Around 2005, Linux and Unix systems started using virtualization technology to expand hardware capabilities, control costs, and improved reliability and security that hypervisors provided to these systems.
OpenFlow
OpenFlow is a protocol that allows a server to tell network switches where to send packets. In a conventional network, each switch has proprietary software that tells it what to do. With OpenFlow, the packet-moving decisions are centralized, so that the network can be programmed independently of the individual switches and data center gear. It is used for applications such as virtual machine mobility, high-security networks and next generation ip based mobile networks. Several established companies including IBM, Google, and HP have either fully utilized, or announced their intention to support, the OpenFlow standard.
Surface computing is the term for the use of a specialized computer GUI in which traditional GUI elements are replaced by intuitive, everyday objects. Instead of a keyboard and mouse, the user interacts directly with a touch-sensitive screen.It is a natural user interface. Surface computer was created by Microsoft with surface. The term "surface" describes how it's used. There is no keyboard or mouse. All
interactions with the computer are done via touching the surface of the computer's screen
with hands or brushes, or via wireless interaction with devices such as smartphones, digital
cameras or Microsoft's Zune music player.
Voice Morphing
Voice morphing (also known as voice transformation and voice conversion) is the software-generated alteration of a person's natural voice. The purpose may be to add audio effects to the voice, to obscure the identity of the person or to impersonate another individual. There are basically three inter-dependent issues that must be solved before building a voice morphing system. Firstly, it is important to develop a mathematical model to represent the speech signal so that the synthetic speech can be regenerated and prosody can be manipulated without artifacts. Secondly, the various acoustic cues which enable humans to identify speakers must be identified and extracted. Thirdly, the type of conversion function and the method of training and applying the conversion function must be decided.
FogScreen
The FogScreen is a new invention which makes objects seem to appear and move in thin air! The FogScreen is a suspensible device that creates a thin, smooth fog surface almost instantly when it is switched on. It can be used for image projection just like a conventional screen. FogScreen is, however, a screen you can walk through! The fog, made of ordinary water with no chemicals whatsoever, dissolves in seconds by itself, leaving no trace behind when you switch it off. The viewer can walk through the screen – walk directly into the picture! People and things can be brought into view through the screen. There are numerous other ways to use the FogScreen.
Microsoft Silverlight
Microsoft Silverlight is a cross-browser, cross-platform implementation of the .NET Framework for building and delivering the next generation of media experiences and rich internet applications (RIA) for the Web. Silverlight uses the Extensible Application Markup Language (XAML) to ease UI development (e.g. controls, animations, graphics, layout, etc) while using managed code or dynamic languages for application logic. Silverlight is a browser plug-in approximately 4MB in size, it is client side free software for easy and fast less than 10 sec one time installation available for any client side browsers. Silverlight supports the display of high-definition video files, and sending them over the Net.
Blade server
A blade server is a compact, self-contained server that consists of core processing components that fit into an enclosure with other blade servers. A single blade may consist of hot-plug hard-drives, memory, network cards, input/output cards and integrated lights-out remote management. The modular design of the blade server helps to optimize server performance and reduce energy costs. Each blade typically comes with one or two local ATA or SCSI drives. For additional storage, blade servers can connect to a storage pool facilitated by a network-attached storage (NAS), Fiber Channel, or iSCSI storage-area network (SAN).
