Raspberry Pi- An Educational Tool



Raspberry Pi- An Educational Tool

Raspberry Pi is a single-board credit-card-sized computer. It was developed by Raspberry Pi Foundation in UK. The objective behind its development was the introduction of basic computer science in schools. It is so simple to program as well as cheap to tamper during experiments. The idea of Raspberry Pi was proposed in 2006 by Eben Upton and a group of teachers, academics and computer enthusiasts at Cambridge University. The initial slot was manufactured in Chine and Tiwan. It was released on 29th February 2012. About half million units were sold within six months of its release.
Raspberry Pi has two models named as Model B and Model A. Model B came initially and then Model A came in the starting of the year 2013. The device has 5 volt USB. A 1200 mA power supply is more than sufficient to run it. 1 Amp is the maximum power that Raspberry can use. An external powered USB hub is required to connect USB device above 1 Amp. Basically, Model B uses 700-1000mA and Model A uses maximum of 500mA. There are no peripherals attached to Model A.  Primarily, Raspberry uses Linux kernel- based OS. In July 2012, Raspbian was released as a free Operating System for this device. Python is a recommended programming language for Rasberry Pi by Raspberry Pi Foundation. Users are not limited to use Python. C, C++, JAVA, RUBY, etc. are all other languages which come installed in Raspberry Pi by default. NOOBS (New Out Of Box Software) is the new tool for Raspberry Pi which helps in installing Operating Systems easily. A recovery partition is also provided in this device that helps in quick restoration of installed OS.
Raspberry Pi Foundation along with its partners is working on the development of software material. They are also working on its use as a teaching platform for all subjects.
