Yes we are referring to Raspberry Pi Low In Cost (Less than Rs.3000/=), Tiny In Size (Credit Card Size) Yet capable Like Desktop!
As defined on their website https://www.raspberrypi.org The Raspberry Pi is a low-cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. You can buy it online in India at https://www.crazypi.com
What an amazing computer it is! Though bit technical when it comes to setting up but; comes with their very own Free Operating System Raspbian (You need to follow certain steps to make it install and RUN); Welcome to the world of Open-source & affordable computing.
Can you use it as smooth as you are using Rs.25,000/= + Software Cost desktop; difficult but not impossible; if you are already a person who loves to play around with technology; ready to research on Internet and has very limited need such as Internet connection, Email, word-processing & spreadsheet you are all set to go.
If this is the case then where's the real adoptability to Raspberry? Ideally at the learning and experimenting stage of computing. Visit https://www.raspberrypi.org/resources/make/ to see the kind of projects you can make it work using Raspberry PI; its learn with FUN! Perfect computing machine for school and college project.
Having said that; Don't just take it as kids' electronics toy; we have seen implementation of the device in real world too; check this site http://e-gyaan.in/ which is working on implementing powerful server at school level and suggesting student to carry Raspberry pi which is then connected on school's desk with Monitor, keyboard & Mouse; Student need not carry loads of bag-pack! Their interactive learning, course material stored on power packed machine which they can carry in their pocket!
The other environment where it can work too is client-server environment; where in powerful server installed with client / actual users given only a dump terminal to view data from server; processing is getting done at server-end and results displayed at client end. Normally client required to start and get Login access and then it completely use resources of server. Though raspberry PI can act as semi smart machine as it also has its own storage and if needed user can carry it easily and plug-in any standard computer monitor or even TV which gives them full mobility.
It's all about finding alternate way of computing low in cost but yet as powerful as branded computer. Mission is making computing affordable to masses. Lets start with Raspberry PI!
