Children Education Sector
Based on the ICT needs of kids, a group of Cambridge students set a target to revolutionize the world. Availability of cheap processors and huge decrease in hardware cost as well as RAM cost made it possible to offer a complete computer system at abt $35. That's what we call the Raspberry Pi revolution! Although it caters perfectly for the kids' IT needs,

Google Support
Even Google is also helping the RaspberryPi revolution and it is gaining wide popularity in the education sector. In fact 15000 units of such devices have been granted to UK schools by Google.
If Google believe in this foundation, it is a very positive sign for ites evolution.
It is no longer only a kids play. Much more can be done and it is simply a fantastic portable device.

ARM Processor with Broadcom VideoCore IV
The device has the Broadcom-BCM2835 system on a chip with ARM processor which can be clocked to up-to 1GHz, VideoCore4 Graphics processing Unit with 512mb of Random Access Memory. SD Cards are used for the booting up of the computer. It runs on Linux based operating system.s
RaspberryPi Popularity
In 2012, the sales boosted so much that some customers had to wait for more than six months to receive their order. Thousands of units are being delievered every day and the stores are flooded with orders. However, the manufacturer has increased prodcution and there seems to be no more order backlog. So if you want to try this very very affordable computer system, this is the time. Grab one and connect it to your PC Monitor or TV set.
Raspberry Pi Foundation
The Foundation is a British charity organisation, not for profit and it seems every launch they make is so widely received that they have difficulty in handling the orders. This can probably be explained by the fact that they do not have a sufficient margin on their products which finally is curtailing their success. Victim of its own raspberry pi buy success!
The computer can be used to play old Atari 2600 games! yeah, this is a good news for the last era gamers who do not find their place in the current gaming market. Besides, you can use it as a secondary device to browse the internet, do spreadsheets, type a letter, play hd movies, play games or just do some normal PC works. It is simply great for the price being offered.
Hardware
The device comes in 2 versions called Model-A and Model-B each with a different configuration specs. They are fitted with:
RCA-video port
Audio port (3.5mm)
USB port
microUSB port for power
card slot - SD Card
HDMI port
700Mhz Broadcom SoC.
The devices can use various output connectivity by using adapters. The basic ports available are sufficient for all decent connectivity. The device has been design to remain simple and low cost which explains why it is not fitted with all sort of fancy ports.
2 Model Versions
Model A costs about $25 with 128MB RAM but no Ethernet connectivity.
Model B boosts the RAM upto 512MB and include a 2nd USB 2.0 port along with 10/100 Ethernet network port.
Both Models boots a Linux OS using a Sd card. Hard disk can take over once the boot process is done.
The foundation launched its own app store and there are dozens of title already available. It has partnered with IndieCity and Velocix to put in place the raspberry pi buy market. Users can upload content and contribute to this revolution. Other users can download same. This website is not affiliated with Raspberry Pi Foundation. We provide independent reviews and guide.
