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
Difference Between Logical and Physical Network Design Abstract Connecting computers together to create a network greatly increases the communication capabilities and can even save a company substantial amounts of time and money. A well thought out network design from a small home network to a large corporate intranet can be a deciding factor in the success of a network. Two important steps in the designing of a successful network are the logical designing phase and physical designing phase. The difference
Difference between Logical & Physical Design of a Network When we look at the differences between logical design and physical design of a network it is easy to think of it as the logical as the functional part and physical as the seeing it part. With that stated there is more to this than just the functional and seeing parts. In order to understand the differences from one to the other, we need more information. In the following paragraphs I will try to outline what makes up the differences between
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 and then
Abstract This paper will explain several differences between a logical network design and the physical design of a network. Most people tend to think of it as the logical meaning the functional part and the physical as the seeing it part. With saying that one must understand that there is more to the logical and physical design of a network than just the functional and seeing parts. In order for one to understand the differences of how the two operate and work from one to the other, one would
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 of a network
Introduction Have you ever listened or sat in on a concept or network design meeting and been fed an alphabet soup of acronyms and words or technical jargon that just didn’t make sense to you? Well, the chances are that Ethernet, Token Ring, FDDI, and Wireless were among some of those being spoken. In this writing, the author plans to help one understand, in simple terms (where possible), what exactly these technologies are and where they may belong. He provides an overview of each, explains the
is intended to be an introductory technical article; certain details have been excluded in the interests of space and clarity. Network design examples are presented to illustrate specific technical points and are not intended to fully complete. Historically WAN’s (Wide Area Networks) and LAN’s (Local Area Networks) have relied on independent technologies. At a physical layer WAN technologies today continue to be based largely on legacy TDM systems that were built initially to support voice, video
Magnetic Disks (Hard Disk) The topic of magnetic disks is one that involves many physics related phenomenon. The intricate structure and design of “Magnetic Disks” (or hard disks) in computers include the principles of Fluid Flow, Rotational Motion, Electromagnetism, and more. This paper will focus mainly on the previously listed physics occurrences, and the design that goes into engineering the magnetic disk to include them. These physics principles are utilized in such a way that makes the hard disk
Thin Client vs. Fat Client & Network Design Considerations Introduction Network computing was created in an effort to allow users of a computer application to share data more easily than using stand alone computers. Clients on a client/server network store their application data on a central server. There are two categories of clients on a network. They were originally categorized by their hardware design, but today clients are categorized by the software application design and where the bulk of the
Difference Between Logical Design and Physical Design (Graphics Not Available) Understanding network topology can tell one a great deal about installing or expanding a network. At its basic level, the topology of a network refers to the way in which all its pieces have been connected. That is, it refers to the layout of the computers, printers, and other equipment hooked to the network (TechTarget 2006). Because cables connect computing resources together for a network, network's topology is also
In designing a network, it is essential to first determine the scope of the project by asking key questions that will aid in the design and build. Questions such as how many servers and computers will be connected, what is the intended purpose of the network, and how much money is available are basic questions that come immediately to mind. Other questions such as security considerations, and how will the physical architecture of the building affect the design are often ignored but are equally
Existing network analysis in an important step when designing a new network as it establishes relevant information about the current network infrastructure and its bottlenecks. It is also a tool that helps to establish the needs and requirements of the company. Requirements of the networks in terms of the application and services are what drive the design of the network. This chapter reports on the outcome of the network analysis, giving details on the existing network design, hardware, protocols
services to the layers below it. The three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process. This presentation will provide you with an understanding of each of the seven layers, including their functions and their relationships to each other. This will provide you with an overview of the network process, which can then act as a framework for understanding the details of computer networking
The Basics of Network Management In the computer world, networks are the primary means of inter-computer communications. The building and maintenance of a network is the responsibility of the network manager. The network manager must have the expertise to design and implement an appropriate network for his client. The proper design of a network is based on more than a few principles. However, the job of the network manager encompasses more than simply building a useable network, although that
Physical Health and Community Design (Allison & Battisto, 2005) The Centers for Disease Control has correlated the incidence of heart disease, diabetes, cancer, and stroke with physical inactivity. By encouraging walkable neighborhoods for children, teens, adults, and elders, we have the opportunity to reverse this trend and create healthy communities by design. There is growing evidence that our physical health is directly tied to our physical activity. Although people
the precise amount of network capacity in the right place at the right time is no simple task. Network Planners cannot afford to overbuild, as this would consume scarce investment resources that could be better used elsewhere. They also cannot delay expansion as this may result in poor service to customers and under-utilize other network assets. A balanced approach is needed in order to meet the rapidly growing and changing traffic demands. Advanced network planning and design software provides benefit
What would you do if you felt that there were no equal opportunities for you to learn? All learners are unique and require different needs and scenarios to succeed. Universal Design for Learning increases access opportunities for every student. With the increasing amount of disabled students inside current schools, Universal Design for Learning should be a change that every school seeks to find. In 1975, the Individuals with Disabilities Act also known as IDEA, mandates that children and youth ranging
