Network Design: Logical and Physical Design In networking terminology‚ the term network topology refers to the entire structure of the network. There are two primary parts to the topology definition: the physical design‚ which is the actual layout of the wire (media)‚ and the logical design‚ which defines how the media is accessed by the hosts. The physical designs that are commonly used in networks are the Bus‚ Ring‚ Star‚ Extended Star‚ Hierarchical‚ and Mesh. A bus topology uses a single backbone

Physical vs. Logical Network Design Bob Jones NTC 410 Fernando Casafranca April 11‚ 2006 How is your network designed? This is a simple question. But‚ like many things in the information technology field‚ not a question with a simple answer. The definition of network design to a customer or user can be completely different than to an information technology professional. Even inside of the information technology field‚ there are several definitions of network design. We use the words Logical

Logical vs. Physical Network Design The typical Top-Down approach to network design uses a systematic method to plan‚ design‚ and implement a new network. Generally‚ the Top-Down methodology involves analysis of the business requirements and goals‚ development of the logical design based on such goals‚ development of the physical design‚ and a phase for testing‚ optimizing‚ and documenting the network design. This paper focuses on the activities performed to create a logical design of a network

A strong topology control of the network is important. A wireless sensor network is formed using the amalgamation of wireless powered sensors. Control of the topology through every node for the transmission power adjustment is efficient in increasing the time of the network and raising the capacity of the network. With a decreased transmission

The Physical Data Model (PDM) describes how the information represented in the Logical Data Model is actually implemented‚ how the information-exchange requirements are implemented‚ and how the data entities and their relationships are maintained. There should be a mapping from a given Logical Data Model to the Physical Data Model if both models are used. The form of the Physical Data Model can vary greatly‚ as shown in Figure 31. For some purposes‚ an additional entity-relationship style diagram

Logical and Physical Network Design Logical and Physical Network Design Network design is a process that begins from the first thought on how to connect to computers together in order for them to communicate and pass needed data to each other. The process may seem simple on this level and may require little consideration‚ but in fact‚ there are many areas of the network that need to be examined before the process of networking should be undertaken. For the small network‚ these considerations

assume that what they do in cyberspace is private if no one in physical space is watching them (Regan‚ 384). Mostly they continue to behave like this until they face with a privacy violation. In order to act in cyberspace properly‚ understanding the difference between physical space and cyberspace privacy is crucial. Crowded streets‚ enclosed malls‚ thin walls and gated mansions are examples of different level of private places. In physical space it is possible to set privacy level easily because of

CONTENT The difference of culture impacts so much to the way to living‚ the way of thinking and the way of doing business. America and Vietnam have a big difference in culture‚ religion and business. However‚ we live in a world where it is called flat world‚ where there is no restriction between countries. It requires us to integrate in order to

The Logical and Physical Design of a Network When a network is being designed‚ the architect must first think about the logical layout and that should be enforced. When he figures out what devices need to communicate and how‚ a physical design of the network can be implemented. A logical design is the reasoning of a network‚ with no particular devices or locations chosen. The physical design of the network is when the devices are picked and their actual location determined. When the logical design
