HOW MUCH DATA DOES THE WORLD NEED? We’re connected – with the whole world. We can share the newest holiday photos on social networks. We communicate with friends all around the world. We listen to music from the cloud. We shop online. We allow ourselves to be guided by our smartphones. 2,800,000,000,000,000,000,000 bytes of data. That’s enough to fill 660 billion DVDs. According to a study, the volume of date will have increased to 40 zettabytes by 2020. A zettabyte, that is 1, 000,000,000,000,000,000,000 Bytes – one number with 21 zeroes. 2,800,000,000,000,000,000,000 Bytes of dataThe advantages of virtual drives and cloud computing are, at first glance, quite evident. The products are becoming more affordable and our whole life is immediately within reach regardless of where we are. Does anyone really have an overview of what happens with this data? The fact is that at the moment, only three percent of this data has been assigned keywords and even less has been analysed. It is a big challenge for us in terms of how we deal with this data. For just as with every technological advance, this technology is a double-edged sword. For example, we leave behind daily a virtual footprint but complain in the next breath about our increasing exposure.
