Digital InnovationThe 4 horsemen of digital innovation: Mobile, Social, Data, CloudMobile: not just smartphones, all kinds of mobile technologySocial: Social media (facebook, reddit, linkedin); tons of opportunities for these social platforms.Data: we have tons of data/information (data is just unprocessed information, like a fact; information is when data is processed data)Cloud: Backs up super-computers, not just one center place, where “internet” came from.Computer Architectures1st generation of first architecture was mainframe architecture/perimeter security (first IBM)2nd generation of architecture client servers (PC’s), wide area networks and local area networks.
