GRID COMPUTING

Image
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...

Importance of the Guru in our life

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...

Safety Capacitors First: Class-X and Class-Y Capacitors

Image
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, pow...
