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.
Volume, velocity, and variety: Understanding the three V's of big data. For those struggling to understand big data, there are three key concepts that can help: volume, velocity, and variety. These three vectors describe how big data is so very different from old school data management.
