Chapter 3 MIS

• "3D Printing Our Own Drones Isn't Going to Save Us Enough Money."
• Investigating using 3D-printed parts to make drones in-house

  1. Cost-savings

  2. Greater flexibility updating current fleet
• Not enough parts can be replicated
• Nonprintable component parts
• Maybe not compatible with internal systems
• Passive recharging platform using 3D-printed parts a huge success
• Frustrating, costly to be on "bleeding edge"
• Central processing unit (CPU)

  The brain
• CPUs

  • Vary in speed, function, cost
• CPU

  Works in conjunction with main memory (RAM)<|>Reads data and instructions from memory<|>Stores results of computation in memory

  Altering of reality by overlaying digital information on real-world objects
• Mixed reality (MR)


  Combination of the real physical world with interactive virtual images or objects
• Virtual reality (VR)


  Completely computer-generated virtual world with interactive digital objects
• Self-driving cars may make things easier, cheaper, safer
• Self-driving cars may eliminate need to have multiple cars
• Self-driving cars may avoid costly traffic tickets, parking tickets, DUI citations
• Businesses disrupted by self-driving cars

  • Auto sales
  • Auto loans
  • Insurance
  • Collision repair shops
• More jobs for engineers, programmers, systems designers with self-driving cars
• More computer hardware, sensors, and cameras in self-driving vehicles
• New from CES 2017
