network topology Thus, a tree network is a bus network of star networks. Logical (or signal) topology refers to the nature of the paths the signals follow from node to node. In many instances, the logical topology is the same as the physical topology. But this is not always the case.

2 Overview of Logical Design Logical vs. Physical. If you are reading this guide, it is likely that your organization has already decided to build a data warehouse. Moreover, it is likely that the business requirements are already defined, the scope of your application has been agreed upon, and you have a conceptual design.

Encyclopedia Definition of:logical vs. physical. High-level versus low-level. Logical implies a higher view than the physical. Users relate to data logically by data element name; however, the actual fields of data are physically located in sectors on a disk. For example, to find out which customers ordered how many of a particular product, the logical view is customer name and quantity.

Topology In mathematics, topology (from the Greek τόπος, place, and λόγος, study) is concerned with the properties of space that are preserved under continuous deformations, such as stretching and bending, but not tearing or gluing.

What is a Topology? The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations.Logical topology was discussed in the Protocol chapter.he physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations.

Network topology In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch. The switch is the server and the peripherals are the clients. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph with the topology of a star.

Types of Network Topology STAR Topology. In this type of topology all the computers are connected to a single hub through a cable. This hub is the central node and all others nodes are connected to the central node.

Logical volume management Logical volume management - Design. 1  Most volume-manager implementations share the same basic design. 2  Normally, PEs simply map one-to-one to logical extents (LEs). 3  The system pools LEs into a volume group (VG).

Media and Topologies for the Network+ Exam The mesh topology is not commonly implemented. In a bus topology, each device is connected to the network through a single connection. In a ring topology, each device is connected to the network through a single connection. In a star topology, each device is connected to the network through a single connection. Answer D. The layout of the network is referred to as the topology. The logical topology defines how the devices connected to the network see it, and the physical topology defines how the network is actually laid out.

Network topology The simplest topology is a permanent link between two endpoints (the line in the illustration above). Switched point-to-point topologies are the basic model of conventional telephony. The value of a permanent point-to-point network is the value of guaranteed, or nearly so, communications between the two endpoints.

Network topology Network topology is the layout of the connections (links, nodes, etc.) of a computer network. There are two main types of topology. Network topologies may be physical or logical. Physical topology means the physical design of a network including the devices, locations and cables.

- Hi. Look here; http://www.freepatentsonline.com/6816915.html. I/O Topology refers to the relative arrangement and communication within the input /output (the I/O of course stands for input/output) pathway used for input and output devices to communicate with the computer processor. In layman terms, it is a logical roadmap of how the CPU communicates with the PCI bus in a computer.

What are Conceptual, Logical and Physical Data Models? A logical data model is a fully-attributed data model that is independent of DBMS, technology, data storage or organizational constraints. It typically describes data requirements from the business point of view.

Tree Topology: Advantages and Disadvantages Tree Topology integrates the characteristics of Star and Bus Topology. Earlier we saw how in Physical Star network Topology, computers (nodes) are connected by each other through central hub. And we also saw in Bus Topology, work station devices are connected by the common cable called Bus.

Physical and Logical Databases This section distinguishes between the logical and the physical database. For this topic, the logical database is the structure of the data and the relationships between different pieces of information. There is no information about how these structures and relations are implemented.

High-availability cluster The terms logical host or cluster logical host is used to describe the network address that is used to access services provided by the cluster. This logical host identity is not tied to a single cluster node. It is actually a network address/hostname that is linked with the service(s) provided by the cluster.

- In computer networking, topology refers to the layout of connected devices. This article introduces the standard topologies of networking. Topology in Network Design. Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network.

What is a Topology? Star. A star topology is designed with each node (file server, workstations, and peripherals) connected directly to a central network hub, switch, or concentrator (See fig. 2). Data on a star network passes through the hub, switch, or concentrator before continuing to its destination.

- 1 In a bus topology, the computers are connected in a linear fashion on a single cable. 2  Bus topologies require a terminator on each end of the cable. 3  In a star topology, the computers are connected to a centralized hub. 4  Mesh topologies connect all computers in a network to one another with separate cables. The physical layout of computers on a network is called a topology. 2  There are four primary topologies: star, bus, ring, and mesh. 3  Topologies can be physical (actual wiring) or logical (the way they work). 4  In a bus topology, the computers are connected in a linear fashion on a single cable.

- Essentially, it is the topological structure of a network and may be depicted physically or logically. Physical topology is the placement of the various components of a network, including device location and cable installation, while logical topology illustrates how data flows within a network, regardless of its physical design.

- A: The basic examples of network topologies used in local area networks include bus, ring, star, tree and mesh topologies. A network topology simply refers to the schematic description of how connecting lines and nodes are arranged in a network. A topology can either be described as physical or logical.
