Hacking

Hacking (English verb to hack, singular noun a hack) refers to the re-configuring or re-programming of a system to function in ways not facilitated by the owner, administrator, or designer. The term(s) have several related meanings in the technology computer science fields, wherein a "hack" may refer to a clever or quick fix to a computer programe problem, or to what may be perceived to be a clumsy or inelegant (but usually relatively quick) solution to a problem, such as a "kludege".

DNA Computer

DNA computer uses a form of computing which uses DNA,biochemistry and molecular biology instead of the traditional silicon-based computer technologies. DNA computing, or, more generally, biomolecular computing,is a fast developing interdisciplinary area.

HVD

The Holographic Versatile Disc (HVD) is an optical disc technology. It can hold many times the amount of information of a Blue ray disc. It employs a technique known as collinear holography, whereby two green laser beams are collimated in a single beam.

Grid Computing

Grid computing is the combination of computer resources from multiple administrative domains for a common goal. Grid computing (or the use of a computational grid) is applying the resources of many computers in a network to a single problem at the same time - usually to solve a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data.

SNIFFER

This time i am giving you presentation on SNIFFER a networking component. it is also known as a packet analyzer also known as a network analyzer, protocol analyzer or sniffer, or for particular types of networks, an Ethernet sniffer or wireless sniffer .it is a computer software or computer hardware that can intercept and log traffic passing over a digital network or part of a network. the main task of sniffer is to captures each packet and, if needed, decodes and analyzes its content according to the appropriate RFC or other specification.enjoy this report on latest technology.

GPRS

 General packet radio service (GPRS) is a packet oriented mobile data service available to all users of the 2G cellular communication systems global system for mobile communications (GSM), as well as in the 3G systems. In 2G systems, GPRS provides data rates of 56-114 kbit/second.
GPRS data transfer is typically charged per megabyte of traffic transferred, while data communication via traditional circuit switching is billed per minute of connection time, independent of whether the user actually is using the capacity or is in an idle state. GPRS is a best-effort packet switched service, as opposed to circuit switching, where a certain quality of service (QoS) is guaranteed during the connection for non-mobile users.
 The presentation consist of the main bone structure of the GPRS and the components which it contains.
