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.
4. Concluding remarks. The objective of this paper is to describe, review, and reflect on big data. The paper first defined what is meant by big data to consolidate the divergent discourse on big data. We presented various definitions of big data, highlighting the fact that size is only one dimension of big data.
