Current authentication systems suffer from many weaknesses. With all the means of technology developing, it can be very easy for ‘others’ to fabricate or to steal identity or to hack someones password. Users nowadays are provided with major password stereotypes such as textual passwords, biometric scanning, tokens or cards (such as an ATM).
BitTorrent is a protocol that enables fast downloading of large files using minimum Internet bandwidth. It costs nothing to use and includes no spyware or popup advertising. Because of the nature of this protocol, large files can be handled more efficiently than thetypical client/server method. The protocol was designed in April 2001 and implemented in Summer 2002 by programmer BramCohen, and is now maintained by BitTorrent.
Abstract : Major recent developments by the Engineers in the underwater construction of locks and dams include the in-the- wet construction method. Underwater Concreting uses precast concrete modules as the in situ form into which concrete is placed directly underwater. The underwater concrete is designed to work in composite with the precast concrete. In depth studies have shown that… Read More »
Recent advancements in data intensive computing for science discovery are fueling a dramatic growth in use of data-intensive iterative computations. The utility computing model introduced by cloud computing combined with the rich set of cloud infrastructure services offers a very attractive environment for scientists to perform such data intensive computations. The challenges… Read More »
Micro-Electro-Mechanical Systems or MEMS technology can be defined as miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of micro fabrication. The critical physical dimensions of MEMS devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters. Likewise, the types of… Read More »
A Storage Area Network is a high-speed sub network of shared storage devices. A SAN’s architecture works in a way that makes all storage devices available to all servers on a LAN or WAN. A Storage Area Network can be anything from two servers on a network accessing a central pool of storage devices to several thousand servers accessing many millions of megabytes of storage.
