With the explosion of the public Internet and e-commerce, private computers and computer networks, if not adequately secured are increasingly vulnerable to damaging attacks. Hackers, viruses, vindictive employees and even human error all represent clear and present dangers to networks. And all computer users from the most casual Internet surfers to large enterprises could be affected by network security breaches. However, security breaches can often be easily prevented. How? This presentation provides you an overview of the most common network security threats and its solution which protects you and your organization from threats, hackers and ensures that the data traveling across your networks is safe.

Some history of networking is included, as well as an introduction to TCP/IP and internetworking. We go on to consider

Artificial Intelligence (AI) is a field of computer science that explores computational models of problem solving, where the problems to be solved are of the complexity of problems solved by human beings. Artificial Intelligence is the study of how to make computers do things, which, now, people do better. The central problems of AI include such traits as reasoning, knowledge, planning, learning, communication, perception, and the ability to move and manipulate objects. This paper elaborates the new approaches to AI. Artificial intelligence in the future will churn out machines and computers, which are much more sophisticated than the ones that we have today. It is expected that the robots in future, will take on everybody's work.Whether it is office work or the work at home, robots will accomplish it even faster and efficiently than human beings will.
