The Raspberry Pi

What is this Raspberry Pi truly ?

Raspberry Pi is a credit card or ATM card size small computer. Even though this device is small in size tasks this device could perform is not small.like typical computer, the Raspberry Pi could be connected with a computer monitor, a key board and mouse. also it could be program to run a small program. It could configure to run services such as MySQL server, Apache web server etc. Also the operating system include common applications such as Word processor, Spread sheet and web browser to browse Internet. the unit contain a powerful video processor to play high definition video.

who invent this Raspberry Pi?

around 2006 number of student to Computer science department and their knowledge in computer science of Cambridge university of UK was declining. As a solution, Eben Upton, Rob Mullins, Jack Lang and Alan Mycroft who served in Computer Science Lab of Cambridge University of UK, think of producing a small, low cost computers for teaching and learning. The team come up with few designs but eventually have to give up, due to non availability of low power microcontrollers and high manufacturing cost.
Later the team, teamed up with CEO of Norcott Technologies, Pete Lomas and Co-inventor of Computer game 'Elit', David Barben to form Non profitable organization, 'Raspberry Pi Foundation'.
after three years the foundation come up with the initial design of Raspberry Pi. After initial tests and corrections, The organization Launched and began selling of 'Raspberry Pi Model A' on February 29th 2012 6 O'clock in the morning of Greenwich Mean Time. after two years the sales count of unit exceeds 2 Millions.
Since then the Raspberry Pi foundation has launched 11 models and according to the magazine 'MagPi' published, total sales count exceeds 12.5 millions.

The released models are,

Raspberry Pi 1 Model A
Raspberry Pi 1 Model A+
Raspberry Pi 1 Model B
Raspberry Pi 1 Model B+
Raspberry Pi 2 Model B
Raspberry Pi 3 Model B
Raspberry Pi ZERO
Raspberry Pi ZERO W
Raspberry Pi Computer Module 1
