Sharing of knowledge has been a mainstay of human interaction from our very beginnings and we have developed methods of transferring information far beyond face-to-face oral tradition. From using visual and audio signals across distances via smoke signals as well as drums and wind instruments, to developing telegrams, radio, televisions and the internet, humans have harnessed our imagination and innovation to develop new ways in which to share critical data with each other. As progress drives forward, the amount of data we need to share has grown exponentially and, thus, the capacity required for storing and sharing such information must also grow.
