WHAT IS RASPBERRY PI?
The Raspberry Pi is a small computer about the size of a credit card and costs approximately 2700₹. It was developed in the UK by the Raspberry Pi Foundation with the hope of inspiring a generation of learners to be creative and to discover how computers are programmed and how they function.
This small computer features amazing HD (high-definition) quality video playback, sports high quality audio and has the ability to play 3D games. The device uses the ARM processor which does most of the hard work in order to run this computer.
ARM processors can be thought of as the brains of the device. These processors are mainly used in small devices such as mobile phones, hand held mobile gaming devices and other small digital devices. The reason for this is that ARM processors are extremely efficient and fast when used in small devices. This makes the ARM processor the obvious choice for the Raspberry Pi. Even though the Raspberry Pi is a computer it does not have a hard drive like traditional computers, instead it relies on the MicroSD card for the starting up and storing of information. MicroSD card does the same job as a hard drive does in a traditional computer.
The MicroSD card must contain the operating system, programs and the data needed to run the Raspberry Pi. The operating system tells the Raspberry Pi how to function, how to handle any input from the user and how to manage programs when they are running.
There are several different versions of this board available in market. The current version is Raspberry Pi 3 with built in WiFi and Bluetooth Low Energy.
