Computers are being used for various purposes today like weather forecasting, machinery operations, guidance of spacecraft and technology. Apart from these in the medical sector, it provides a great helping hand in storing information that could be referred later, in space technology, automation in banks, ticket booking through the net, traffic control, and even games could be played in computers on and many more. All these are possible only because of the characteristics that a computer posses like speedy, accuracy, reliability and integrity. It could executive over a billion instructions per second without committing any mistakes is completely reliable. The memory of the computer is so vast that it could hold in a large amount of data.
While the technology has been developed primarily by companies in proprietary settings, there has been a new focus on improving it through open-source platforms. New players in the market, such as the startup venture LightSide and edX , the nonprofit enterprise started by Harvard University and the Massachusetts Institute of Technology, are openly sharing their research. Last year, the William and Flora Hewlett Foundation sponsored an open-source competition to spur innovation in automated writing assessments that attracted commercial vendors and teams of scientists from around the world.
