1. Introduction With the rapid development of new communications technology and network technology‚ some industries such as information industry show significant network externality characteristics. Network externality has been defined as "a change in the benefit‚ or surplus‚ that an agent derives from a good when the number of other agent consuming the same kind of good changes" (Liebowitz & Margolis‚ 1996). In other words‚ the product will be more valuable if more people use it. For example

Network Topologies Network topologies are an important part of the network. Without the proper topology‚ the network may not meet the needs of the organization. The layout of a network is referred to as the topology. How nodes in a network are connected to each other and communicate is determined by the topology. There are three basic topologies with several typical variations‚ or combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first topology discussed

volumes and video data‚ especially in real-time applications‚ the use of classic encryption methods like DES‚ AES‚ ...‚ is not efficient in terms of being time cosuming. In this article‚ a new method is proposed to encrypt digital images‚ using chos systems and utilizing DNA patterns. A central idea in the method suggested is to produce a pseudo-random DNA strand using chaos functions‚ which an encrypted strand is created‚ using the random strand and the strand produced from the main image. Also‚ in

Computers and Society Evaluating the Impact of Technology Chris Brooks Department of Computer Science University of San Francisco Evaluating Technological Impact It can be useful to think about the ways in which technology impacts the way we live our lives. Most computer scientists have a pretty positive view of technology. Is that view justified? How do we defend that view to other‚ more skeptical points of view?

Network Hardening Unit 8 Assignment 1 It is very important to go through the process of hardening. Hardening is where you change the hardware and software configurations to make computers and devices as secure as possible. I picked the network layout 1-the workgroup . First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. I would also have some good anti-virus software on the workstations. You also need a hardened image for
