In the time of digital world, there are many part of the world which still do not know what is a computer and how to operate it? The main reason is many people cannot afford it.

I have developed a computer system which includes: 
- Broadcom BCM2835 700Mhz ARM1176JZFS Processor
- 1 GB RAM
- 1 TB USB Hard Disk

So you can prepare the complete computer system within $100-$130. In this computer system the operating system used is Linux which is open source so there is no need to pay for a license.

Even in countries where the poverty level is high they can afford this solution.
This solution also gives more knowledge and learning as Linux is the growing OS in the market. It is highly impactive for the future digital world.
