Mercury is the only common metal which is liquid at ordinary temperatures. Mercury is sometimes called quicksilver. It is a heavy, silvery-white liquid metal. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. It alloys easily with many metals, such as gold, silver, and tin. These alloys are called amalgams.
describe big data, so that you can speak intelligently about it when asked. So probably the main thing to recognize is this notion of the three V's of big data, which are volume, velocity and variety.
By Klarity In Big Data. What is âbig dataâ? Given its widespread usage across mass media environments, it is not surprising that the precise meaning of the term is often vague. Big data can be understood as the convergence of four dimensions, or the four Vâs: volume, variety, velocity and veracity. The 4Vâs is a data management trend that was conceived to help organisations realise and cope with the emergence of big data. Volume. This dimension refers to the quantity of data, as big data is frequently defined in terms of massive data sets with measures such as petabytes and zettabytes commonly referenced. And these vast amounts of data are generated every second. This used to be employee-created data.
