Transaction of information on internet is not a new; it has gone through a lot of transformation. But how much is this transaction secured especially when it comes to critical information related to defense, financial organizations etc. Cyber crooks, network hackers, cyber pirates, internet thieves is an emerging crime category of criminals and threat to online information transactions of data and information. Not only the Banks and financial institutions but almost every organization who have some critical data have put much effort into internet security measures to protect customer and even themselves from fraud. You’re probably familiar with the “two-factor authentication security method” – the bank provides you with a security token, which generates a pseudo-random number for you to use at login, along with other credentials. What if fraudsters managed to over-rule this security measure during your attempt to log into your online bank account. Some of the techniques used by c

One of the basic usage of the TIMER peripheral on every microcontroller is to provide the accurate timing mechanism. Using the TIMER peripheral as the basic timing, we could easily develop a stopwatch and display it to the 8-Digit seven segment numeric LED display. Thanks to the Maxim MAX7219 chip which enable us to interface this 8-Digit seven segment LED display much easier using just three wires of the SPI (serial peripheral interface) to display the hour, minute, second, and hundredth of seconds to the 8-Digit seven segments LED display. The following is the list of hardware, software, and references used to build this project: 1. One Maxim MAX7219: Serially Interfaced, 8-Digit LED Display Drivers 2. Two common cathode 4-Digits seven segment LED display 3. One Resistor: 10K Ohm 4. One Capacitors 0.1uF 5. AVRJazz 28PIN development board from ermicro which is based on the AVR ATmega328P microcontroller. 6. Atmel AVR Studio 6.0 for coding and debugging environment 7.

Let me ask you a question; what according to you is the main reason, the USP (in this case UPP, Unique popularity point) for the immense growth and popularity of the internet/web in the past few years??? Its simplicity, ease of use; what is the underlying factor that has been boosting the internet culture. Internet nowadays is not just a technological achievement; it’s a cult, a living cult whose existence we cannot deny. Remember the days of "Dada-Dadi ki Kahaniyan (Stories by Grandparents)”. There are hundred reasons why you loved them, but the most important out of them is the interaction. When we inquired them about anything there always was a certain answer and that lead to another story. This interactivity was the part that leads to their success and interactivity is the reason I suppose the cause for internet popularity. I agree, you agree, we all agree, but while giving 'Interactivity' a thumbs up aren't we ignoring one important thing like we hav

‘There can be no keener revelation of a society’s soul than the way in which it treats its children ’-Nelson Mandela     A Child is wet clay, one can mould them in any shape or in any forms. It is clay in a potter's hand. From the time immemorial, the concept of 'Age' has always been an unexplored topic in the theoretical aspect of a child in relation to his criminal responsibility. Recognizing the rightful place of a child from a need-based approach to a right-based approach was an apogee in the past years. Child-centric human rights jurisprudence has become one of the vital issues under the plethora of laws in the chauvinist society of today. In present times, there are alarming growths, impatience, intolerance and other negative vibes can be found in a child which needs a holistic development. Historically, in India, children hold an integral position with their family and society as a whole. The main upbringing has always been the immediate family is it joint fami

INTRODUCTION Grid computing is a processor architecture that associates computer resources from various areas to reach an objective. In grid computing, an individual computer can connect with networks of computers that can perform the task together, thus working as a super processor. It is a form of interconnected computer systems where the machines utilize the same resources collectively. The concept of grid computing invented in the early 1990s as a symbol for making powerful computers as easy as to work with power grid. A computational grid is a collection of mixed type of computers and the resources spread across numerous administrative fields with the resolute of providing users easy access to these resources. Speaking technically, Grid computing enables the virtualization of distributed computing and data resources such as processing, network bandwidth and storage capacity to create a single system image, granting users and applications seamless access to vast information tec

The Guru-Disciple tradition is a unique feature of our Indian culture. We celebrate this tradition on the occasion of Guru-purnima which helps us to understand the importance of the Guru in our life. The Guru is the one who takes out ignorance from us. Our teachers are our Guru. That is why, 'Teacher's Day' should be celebrated on the auspicious day of Guru-purnima to offer gratitude at the feet of our teachers. 'Guru' is a term in which 'Gu' means 'darkness' (hidden) and 'ru' means 'removal'. Guru is the one who removes the ignorance of disorder from our life and teaches us how to live a blissful life. The Two Gurus in our life 1. Our Parents are our first Guru, who inculcate good values in us and help us to blend with our society. Our parents teach us everything in our childhood stage. They make us aware what is right and what is wrong. They inculcate good habits in us – for example – Why and how to pay respect to our elders

A Special Class of Capacitors Class-X and Class-Y capacitors are safety-certified capacitors generally designed and used in AC line filtering in many electronic device applications. These safety capacitors are also known by other names, including  EMI/RFI suppression capacitors  and  AC line filter safety capacitors . (EMI stands for electromagnetic interference and RFI stands for radio-frequency interference; RFI is simply higher-frequency EMI.) An example of a Class-Y capacitor  Class-X and Class-Y capacitors help to minimize the generation of EMI/RFI and the negative effects associated with received EMI/RFI. In order for these capacitors to perform their EMI/RFI filtering tasks, they are directly connected to the AC power input, that is, the AC “line” and the AC “neutral” (see Figure 2 below). And because of this direct connection to the AC voltage, the capacitors may be subjected to over voltages and/or voltage transients—lightning strikes, power surges. Thus, capacit
