I n these days of configuring processes and discovering new computer languages we of the “ C O S C I A N ” have great pleasure in presenting “ INNOVA ” . “ INNOVA ” contains a number of small articles presented by a cross section of individuals from the “Department of Computer Science”. To give you a sneak peak here are some of the articles you would come across: You get a peak into the future of computers that are able to make their own intelligent decision. Super charge your old computer and turn into a number crunching monster. Know about the rising cyber crime scenario. And much more. Wishing you one and all a delightful reading experience. We would like to extend our gratitude to the industrious people came forward with their interesting articles. HAVE INNOVATIVE THOUGHTS !!!

ABOUT US ABOUT THE INSTITUTION Hindustan Engineering Training Center (H.E.T.C) educational society laid the corner stone in the field of Arts and Science with the inception of Hindustan College of Arts and Science to establish an educational institution of exceptional merit. Hindustan College of Arts and Science opened its gates to the student fraternity in 1995. It is a premier institution, which is recognized by the Government of Tamil Nadu and affiliated to the University of Madras . The college campus has been meticulously designed and houses state-of-the-art laboratories, well-stacked libraries, cafeteria, spacious auditoriums, and excellent boarding and lodging are available for both boys and girls. We employ a dedicated team of academicians hand picked to impart the highest quality education. HCAS maintains a cosmopolitan atmosphere with students from all corners of the globe studying in its fold. The college is located at Padur, about 22 kms. South of Chennai city, on

WIRELESS TECHNOLOGY WITH BOOMING Increasing demands of the software industries, rapidly growing needs-bundled with information sharing and data transmission had been the greatest challenge for the network researchers. One of the most daunting projects for a broadband user with no networking experience is switching from a single computer connected to a cable or DSL modem to a wireless network. uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens: A computer's wireless adapter translates data (1s & 0s) into a radio signal and transmits it using an antenna. A wireless router receives the signal and decodes it. It sends the information to the Internet using a physical, wired Ethernet connection. The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sendin

ARTIFICIAL INTELLIGENCE What is artificial intelligence(A.I.)? Artificial Intelligence is the science and engineering of making intelligent machines, especially intelligent computer programs. It is similar to the task of using computers to understand human intelligence, but AI does not have to confine itself to methods that are biologically observable. John McCarthy, who coined the term in 1956,defines it as "the science and engineering of making intelligent machines”. Alexander Kronrod, a Russian AI researcher, said “Chess is the Drosophila of A.I.” He was making an analogy with geneticists' use of the fruit fly to study inheritance. Playing chess requires certain intellectual mechanism and not others. Chess programs now play at grandmaster level, but they do it with limited intellectual mechanisms compared to those used by a human chess player, substituting large amounts of computation for understanding. Once we understand these mechanisms better, we can build h
