Five Generations of Computing The history of computer development is often referred to in terms of five distinct eras‚ or "generations" of computing devices. Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate‚ resulting in increasingly smaller‚ cheaper‚ more powerful and more efficient and reliable devices. The First Generation: 1946 to 1955 The first computers used vacuum tubes for circuitry‚ magnetic drums

Computer Crime Computer crimes need to be prevented and halted thought increased computer network security measures as well as tougher laws and enforcement of those laws in cyberspace: Computer crime is generally defined as any crime accomplished through special knowledge of computer technology. All that is required is a personal computer‚ a modem‚ and a phone line. Increasing instances of white-collar crime involve computers as more businesses automate and information becomes an important

Computer Crime This type of crime is the illegal exploitation of computer technologies‚ usually involving the Internet‚ to support crimes such as fraud‚ identity theft‚ sharing of information‚ and embezzlement. Exactly what is illegal varies greatly from state to state. Consequently‚ the growth of international data communications and in particular the Internet has made these crimes both more common and more difficult to police. Luckily there are people fighting computer crime and it is taken very

History of generations of Computers The computers that you see and use today hasn’t come off by any inventor at one go. Rather it took centuries of rigorous research work to reach the present stage. And scientists are still working hard to make it better and better. But that is a different story. First‚ let us see when the very idea of computing with a machine or device‚ as against the conventional manual calculation‚ was given a shape. Though experiments were going on even earlier

undoubtedly the computer‚ arguably the single most complex device ever created by humanity. The computer is the ultimate tool‚ replacing inanimate objects like typewriters‚ notepads‚ calculators‚ photo-albums‚ televisions‚ books; running complex models of attractors‚ road networks‚ the weather‚ the stock market and the universe; and replicating human bank tellers‚ porters‚ telephone operators‚ pilots‚ teachers‚[4] even doctors [5] and artists.[6] Analogies have been drawn between mind and computer‚ but the

Wireless Network Security Partha Dasgupta and Tom Boyd Dept. of Computer Science and Engineering Fulton School of Engineering Arizona State University partha@asu.edu‚ tboyd@asu.edu Abstract Wireless networking is inherently insecure. From jamming to eavesdropping‚ from man-inthe middle to spoofing‚ there are a variety of attack methods that can be used against the users of wireless networks. Modern wireless data networks use a variety of cryptographic techniques such as encryption and authentication

COMMUNICATION NETWORK Communication network are large system distributed in wide area which are designed to send and receive information from one computer to another computer and this computers are called host. Network achieves this providing a set of rules which in terms of networking are called protocols. This protocols are set for communication which every host should follow and participate. The network is made up of two types of components: Nodes and

The LAN configuration is the best option for a productive Small Office/Home Office (SOHO) where periphery contraptions‚ for instance‚ printers and scanners may be bestowed to different PCs on the framework. Making usage of this preferred standpoint makes using a framework more calm than
