Big Data is the latest tech industry buzzword, but what is it and how does it affect us? Well in the simplest terms it denotes a large (very large in fact) amount of data. We’re talking about a classification which deems 30-50 terabytes a “minimum”. To place that into perspective, one terabyte of audio recorded at CD quality will contain around 2,000 hours of audio, while the first 20 years’ worth of observations by the Hubble Space Telescope has equated to more than 45 terabytes of data! This collection of information, which can take a multitude of forms; text, imagery, audio, or even statistics brought about by the number of clicks on one website page, can then be used by organisations to make informed decisions.
