Logical and Physical Design of a Network NTC410 Why is it useful to use both a physical and a logical network design? A physical layout of the network shows the physical location of and the connections between devices participating on the network. In such diagrams‚ workstations are usually represented with small computer icons‚ servers with full tower cases‚ and switches. The Logical Design is the IP structure of your network depending on the services that will be provided to clients

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

Several devices having its own cable that connects to a central hub‚ or sometimes a switch‚ or even a Multi-station Access Unit (MAU). Data passes through the hub to reach other devices on the network. Ring Information is passed from one computer to another in either clock-wise direction or counter clock-wise direction and

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

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 vs. Physical Design of a Network In the world of network design‚ there are two common design types; the logical network design and the physical network design. A logical network design can be described as how the network will be structured‚ basically all logical aspects of the network. According to Webopedia‚ "the logical topology is the way that the signals act on the network media‚ or the way that the data passes through the network from one device to the next without regard to the

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

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

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

1. Topology yang saya pilih adalah Hierarchical Star Topology Pros: • Bisa diimplementasikan pada jaringan yang luas. • Switches bisa dikonfigurasikan secara redundancy untuk menghindari satu kegagalan tunggal uplink. Cons: • Ada batasan ukuran besarnya jaringan seperti design IP address dan juga issue masalah timing jika tanpa memperkenalkan technologi routing. Topologi Bintang adalah cara menghubungkan beberapa unit komputer dalam satu jaringan berbentuk seperti bintang/star. Komunikasi
