We have always seen in Hollywood movies, how a computer system could answer the questions asked by human and we would wonder “Can such things happen in real world ?” .

Well it is no more a wonder, whole world has witnessed this happening when IBM’s Super-computer Watson challenged two all time Jeopardy winner Brad Rutter and Ken Jennings in a special Jeopardy show – “An IBM Challenge “. It was a 3 day challenge where Watson was asked the same question asked to other Jeopardy contestant and the result was, Watson won $1 million and the challenge too .

For those who don’t know what is Jeopardy: Jeopardy! is an American quiz show featuring trivia in history, literature, the arts, pop culture, science, sports, geography, wordplay, and more. The show has a unique answer-and-question format in which contestants are presented with clues in the form of answers, and must phrase their responses in question form.

Watson was named for IBM’s first president, Thomas J. Watson. It is a DeepQA project designed and developed by IBM research team over the last 3 years of time. It is powered using IBM’s power7 servers and has a memory over 15 tera-byte. The big deal here is it gets the answer from this tera-bytes of data stored on its system based on some clues given to it in the form of text file. These clues are in natural language like English.

Watson analyse this query and get the 3 possible answers from its memory, and it does it in a blink. The point to note here is, Watson is not connected to internet, so it has to process the questions asked to him from the data stored in its memory.

In the show Watson was connected to a electronic buzzer which it could press once it is confident about the final answer, at the same time the other contestants who are human can also press their buzzer if they find the answer for the clue before Watson.  First person who have pressed the buzzer get the opportunity to answer the question asked.
