Logical and Physical Network Design

Hello everyone. My name is Randi Griffin. I live in St. Croix on the Virgin Islands. Now I know what you are thinking: Because I live in paradise, my life must be a cake. It's not. I am my wife, mother, and employer. I also like my church very much. Whether I live here or not, life is still life, it is much warmer than the province. My main e-mail address is bear@vipowernet.net and my reserved e-mail address is rgrif@email.uophx.edu. My work and my home phone are the same. (340) 772-6049.

What is a topology? In a LAN, an organization can be represented by a physical topology and a logical topology. The physical topology of a network refers to the placement of cables, computers, and other peripherals. Therefore, it is necessary to avoid confusion between physical topology and logical topology Logical topology is that the actual data transfer method in the network is different from the design. Therefore, the logical topology of the LAN is the signal flow between the connected device and the connected device. The topology can be measured as a virtual shape or placement of the network. However, the shape does not actually match the actual physical design of the device on the computer network. The various topologies that can be used for the LAN are described below. There are five types of topology networks: star, bus, ring, tree, and grid.

The interconnection network topology is the layout of the various elements (links, nodes, etc.) of the computer network. The network topology can be physical or logical. This is the physical topology of the device, including the physical design, location, and wired network. A logical topology is not a physical design but a way in which data is actually transmitted over a network. Forming a network connection, it can use one or more of several interface types, network interface card (NIC) and / or serial device PPP network interface device, multiple computer types etc. . Each computer support network software provides server functions or client functions. Hardware used to transfer data over a network called media. It can include copper, fiber or wireless transmission. Standard wiring is the use of the 10Base-T category 5 Ethernet cable in this document. This is a twisted pair copper wire similar to the surface TV coaxial cable. Answer to Question 1
