Definition:- Li-fi is a technology used for wireless communication. The communication between devices using light as a medium to transmit data at a very high speed. Introduction:- The term Li-Fi was first introduced by Harald Hass at TED Global talks. Professor Harald Hass belongs to Germany and is a Professor of Mobile communication in the University of Edinburgh . Overview:- The working of Li-Fi is pretty similar to Wi-Fi. The only difference being Wi-Fi used radio frequency to transmit data whereas Li-Fi used light to transmit data. The advantage of using Li-Fi over Wi-fi is that it has higher bandwidth and has greater speed on comparison. Technological Stacks:- The optical communication used LED's (light emitting diode) as a medium to transmit data for communication at a very high speed. Visible Light Communication works by switching current to LED's to turn on and off at a high speed. The process is too quick to be identified by the naked human eyes. In oth...

BIOMETRICS:-                Biometrics is an automated methods of recognizing a person based on a physiological or behavorial characteristic.

Child Labour has been a major area of concern for all the developing countries. But for a country with second largest population in the world it remains a key area to be looked upon to improvise the country’s future. ·         The 1998 national census of India estimated the total number of child labourers, aged 4 to 15, to be at 12.6 million, out of a total child population of 253 million in the 5 to 14 age group. However, in 2009–10 a nationwide survey found the prevalence of child labour had reduced to 4.98 million children (or less than 2% of the children in the 5 to 14 age group). ·        The 2011 national census of India found the total number of child labourers, aged 5–14, to be at 4.35 million,] and the total child population to be 259.64 million in that age group. The child labour problem is not unique to India; worldwide, about 217 million children work, many full-time. Guidelines for Child Labour...
