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.
Today big data is generated by machines, networks and human interaction on systems like social media, and the volume of data to be analysed is massive. Variety. Variety refers to the increasingly diversified sources and types of data requiring management and analysis. We used to store data from sources like spreadsheets and databases.
