The future is all around us

• Computers


  • Personal computers (with monitor, keyboard, mouse)
  • Portable computers (laptops, tablets, smartphones)
  • Games consoles
• Personal computers, games consoles, and portable computers represent less than 2% of the computers in the world
• Embedded computers


  Computers that control a specific device and have been designed to carry out a highly specialised function
• Embedded computers might not fit everyone's definition of a computer, as user interaction with them is tightly constrained
• When using the web, you likely interacted with many more computers that you were unaware of, such as web servers
