Raspberry Pi uses Linux Kernel-Based Operating System. It is capable of performing tasks like word processing, working with spreadsheets, can be used for entertainment purpose like playing videos, surfing internet, playing games etc. Raspberry Pi has Broadcom BCM2835 SoC which contains ARM1176JZF-S 700 MHz Processor, Videocore IV GPU and 512MB of RAM.SD card is a memory device used for booting and storage as it doesnot contain any harddisks. Python is used as main programming language and by default it supports C, C++, Java, Scratch, Ruby are also available .This small computer is gaining its popularity in embedded system design.
There are two models of raspberry pi available called Model A and Model B.The only difference between these two model is that Model A has one USB port, no Ethernet controller,256 Mb RAM,power rating of 300mA and costs $25 while Model B has two USB ports, an Ethernet controller,512Mb RAM, power rating of 700mA which costs $35.The Raspberry Pi has 26 dedicated GPIO pins, a UART, an I2C bus a SPI bus with two chip selects, I2C audio ,3.3V ,5V and a Ground.If the numbers of GPIO are required to increase then we can expand it using SPI and I2C bus.
