Computer As a Tool

• Many computers today are embedded
  • Fixed functionality
  • Appliance-like
  • Not really programmable by end user
• Not the focus of this course!
  • Instead, programmable computers
  • Learn to think of computer as a tool
• Program?
  • Algorithm or set of steps that computer follows
  • Human brains wired to work this way
