Network design: logical design and physical design In networking terms, the term network topology refers to the overall structure of the network. There are two main parts of the topology definition: physical design, the actual layout of the line (media), and logical design that defines how the host accesses the media. Common physical designs in the network are bus, ring, star, extended star, hierarchy, and mesh. The bus topology uses a single trunk segment (cable length) to which all hosts directly connect.
The physical design layout provides an overview of the various parts of the logic design network in a particular network architecture. It also refers to the placement of computers and other physical components. Its components include optical fiber, ISDN and Ethernet (Johnson, 2002). The logical design network assumes a specific conceptual design part of the network and assigns a logical role within the framework. Its components include the IP structure of the network, such as Class A, Class B, or Class C address scheme (Johnson, 2002).
Our goal is to design a cost-effective, manageable network that can be flexibly adjusted as the company's business and technology needs grow and change. Logical design represents the network structure. Physical design represents the actual location of network devices, servers, and clients. The physical design of the computer network is easy to understand. For computer users, a network is any device associated with computers and computers that are interconnected through routers, printers, external hard drives, and various forms of communication. While some networks use permanent connections, this is almost always the form of cables. Other networks rely on established temporary connections. Temporary connections are suspended for a certain period of time and then interrupted by telephone or other form of communication equipment.
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
