Around 90% of the data in the world today were created over the past two years (IBM, 2017). This exponential growth has led to the use of increasingly large units of measurement. For example, global annual internet traffic surpassed the exabyte threshold in 2001 and is expected to pass the zettabyte threshold by 2017. (One exabyte is 1 000 000 000 000 000 000 bytes, or 10^18 bytes, and one zettabyte equals 1 000 exabytes, or 10^21 bytes [Figure 1.1].) Internet traffic has tripled over the past five years (Cisco, 2017a).

More than 3.5 billion people, or nearly half the global population, now use the internet – up from only 500 million in 2001 (ITU, 2017). About 54% of households now have internet access at home. In the last five years, global mobile broadband subscriptions increased threefold and surpassed 4 billion active subscriptions in 2017, while mobile phone subscriptions reached 7.7 billion.
