Mobile phones becoming a basic part of life, the recharging of mobile phone batteries has always been a problem. The mobile phones vary in their talk time and battery stand by according to their manufacturer and batteries. All these phones irrespective of their manufacturer and batteries have to be put to recharge after the battery has drained out. The main objective of this current proposal is to make the recharging of the mobile phones independent of their manufacturer and battery make.Now we will explain it by using induction principle.This is based on Inductive charging uses an electromagnetic...

Bluetooth Technology
Bluetooth technology, developed by Ericsson Mobile Communications, a worldwide telecommunications company based in Sweden, is fast becoming the worldwide standard for short-range wireless communication. The technology was originally developed to easily connect cell phones with peripheral devices such as personal computers. However, other potential applications for home and office quickly emerged.Bluetooth is growing so rapidly that Merrill Lynch predicts that by 2005 there will be more than 2.1 billion Bluetooth compatible devices on the market.
Bluetooth uses Radio Frequencies to...
Google's Driverless Car
A car with a top speed of
25 meters per hour, two seats and no steering wheel might not make much of an
impression at a motor show. But Google, in the US, sent a shock through the car
and taxi industries as it unveiled the latest version of its driver-less car.The electrically powered
vehicle, which Google has started testing around its headquarters in Mountain
View, California, dispenses with all the normal controls, including foot
pedals. Instead, it has a smart phone app that calls it and tells it the
destination, and a single STOP button between the two front-facing...
What Is GPS
The
Global Positioning System (GPS) is a system of satellites maintained by the US department of defence for navigation and security purposes. These satellites, which are located the earth is approximately 11,000 miles, follow known orbital paths and broadcast radio
signals communicating their location at a given point in time. GPS receivers are able to determine location by tracking and comparing
signals from multiple satellites.The receiver is able to determine
how long each signal took to travel from the satellite to the receiver and translate this time
interval to a...
Solar Inverter
Solar energy is free and clean. There is enough for everyone, and
we will never run out of it. Solar energy is renewable. The sun will keep making energy for millions of years .Why don’t we use the sun for all our energy needs? We don’t
know how to yet. The hard part is capturing the sunlight. It shines all over
the earth and only a little bit reaches any one place. On a cloudy day, most of
the light never reaches the ground at all.Lots of people put solar
collectors on their roofs. Solar collectors capture the sunlight and
turn it into heat. People can heat their houses and their water using...
Tidal Energy
Tidal means structure changing in a planet,
caused by the gravitational interaction with another planet.The gravitational pull of the moon and the sun cause the changing of the
sea-level twice a day on
the Earth.The period from the smallest water-level, to the highest sea-level
called upstream tides, while the period between the highest and the smallest sea-level is called
downstream tides.The sea-level changing between the rising and the falling of tides is called tidal range. These work rather like a hydro electric scheme, except that the dam is much bigger.
A...
Nano Technology
Nano technology is a latest trend in technologies.It has been demonstrated that nano scale materials exhibit properties which are vastly different from their bulk counterparts. Nanotechnology
is the study of understanding and controlling matter on molecular scale. Generally, nanotechnology deals with dimensions of 100 nano meters or smaller in at least one dimension, and involves developing materials or devices
within that size. Nanotechnology is very diverse, ranging from extensions of
conventional device physics to completely new
approaches based upon molecular...

WI-FI Working
Wi-Fi, also, WiFi, WI-fi or wifi, is a brand originally licensed by the Wi-Fi Alliance to describe the underlying technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications.Wi-Fi was developed to be used for mobile computing devices, such as laptops, in LANs, but is now increasingly used for more applications, including Internet and VoIP phone access, gaming, and basic connectivity of consumer electronics such as televisions and DVD players, or digital cameras.A person with a Wi-Fi device, such as a computer, telephone, or personal digital assistant (PDA) can...
Super Computer
A supercomputer is a
computer that leads the world in terms of processing capacity, particularly
speed of calculation, at the time of its introduction. (The term Super
Computing was first used by New York World newspaper in 1920 to refer to the
large custom built tabulators IBM had made for Columbia University.)
Supercomputers are
used for highly calculation-intensive tasks such as weather forecasting,
climate research (including research into global warming), molecular modeling
(computing the structures and properties of chemical compounds, biological
macromolecules, polymers, and crystals),...

Virtual Servers
Virtual server is a highly salable
and highly available server built on a cluster of real servers. The
architecture of server cluster is fully transparent to end users, and the users
interact with the cluster system as if it were only a single high-performance
virtual server. Please consider the following figure.
The real servers and the load
balances may be interconnected by either high-speed LAN or by geographically
dispersed WAN. The load balancres can dispatch requests to the different
servers and make parallel services of the cluster to appear as a virtual
service on a single IP address,...
Ethical Hacking
Ethical is the discipline dealing with what is good and bad and with moral duty and obligation." More simply, it is the study of what is right to do in a given situation what we ought to do. Alternatively, it is sometimes described as the study of what is good and how to achieve that good. To suggest whether an act is right or wrong we need to agree on an ethical system that is easy to understand and apply as we consider the ethics of computer break-ins.
And Ethical hacking deals with the computer security.This defines the protection of computers the unwanted attacks.
