I am a Computer Engineering student and found the topic name interesting. I dont know anything about it, and I tried lots to find information on this topic. But, could not get a proper guided knowledge about it.Could anyone kindly inform me where I can find the basic information about the subject ? Also, if I were to investigate into more details of this matter, which books should I refer? My email id is sailee_latkar@yahoo.co.in. Please help. Regards, Sailee.
