The world’s information is doubling every two years. In 2011 the world created a staggering 1.8 zettabytes. By 2020 the world will generate 50 times the amount of information and 75 times the number of "information containers", while IT staff to manage it will grow less than 1.5 times. This session introduces students to various storage networking, & business continuity terminologies.
