Raspberry Pi is a small, card sized computer manufactured and designed in the United Kingdom by the Raspberry-pi foundations with intention of teaching basic computer science to school students and every other person interested in learning computer hardware, programming and DIY-Do-it Yourself projects.
The Raspberry Pi have Broadcom BCM2835 system on a chip (SoC), including an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU and was originally shipped with 256 MB of RAM, further upgraded (Model B & Model B+) to 512 MB. It does not include any type of built-in hard disk or solid-state drive, but it …show more content…
While operating at 700 MHz by default, the Raspberry Pi provides a real world performance roughly equivalent to the 0.041 GFLOPS. On the CPU level the performance is similar to a 300 MHz Pentium II of 1997-1999, but the GPU, however, provides 1 Gpixel/s, 1.5 Gtexel/s or 24 GFLOPS of general purpose compute and the graphics capabilities of the Raspberry Pi are roughly equivalent to the level of performance of the Xbox of 2001. The Raspberry Pi chip operating at 700 MHz by default, will not become hot enough to need a heatsink or special cooling.
2) Power source
The Pi is a device which consumes 700mA or 3W or power. It is powered by a MicroUSB charger or the GPIO header. Any good smartphone charger will do the work of powering the Pi.
3) SD Card
The Raspberry Pi does not have any on board storage available. The operating system is loaded on a SD card which is inserted on the SD card slot on the Raspberry Pi. The operating system can be loaded on the card using a card reader on any computer.
4) GPIO
GPIO – General Purpose Input Output
General-purpose input/output (GPIO) is a generic pin on an integrated circuit whose behaviour, including whether it is an input or output pin, can be controlled by the user at run
