Introduction to Raspberry Pi?

  • The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. 
  • It is a little device that enables to explore computing, and to learn how to program in languages like Scratch and Python. 
  • It’s capable to do browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. 
  •  The Raspberry pi has been used by students, hobbyist, technical professional as a starter kit to develop applications and control function around it. 
  • It is also being used in industrial control and as a central processing units which integrate and control the overall system. 
  • Raspberry Pi is essentially a bare-bones personal computer with a Linux operating system installed.
  • These are the current models of the Raspberry Pi available: the Pi 2 Model B, and the Pi 1 Model B+ and A+.
