Logical and Physical Network Design

Introduction

Network design is a detailed, labor-intensive activity. During the design process, all chance on aspects of the profits argon examined in terms of how they meet stream needs and how they must be adapted or overdone as network usage ages. This includes the hardware which constitutes the physical network, the parcel utilize to give that network its structure and organization, and the firmware which gives your network interface controllers and hubs their functionality.

The goal is to design a network that is cost-effective, golden to manage, and has the flexibility to adapt as your companys business and technical requirements grow and change. The logical design represents how the network operates. The physical design represents the material locations of networking equipment, servers, and clients.

Logical and Physical Network Design

The physical design of a calculator network is easier to understand. To a calculator user, a network is manifestly a group of computers and all of the devices associated with computers, from routers to printers to external hard drives, that are connected to each other by a shape of different forms of communications capabilities. Some networks involve permanent connections, which are almost always in the form of cables.



Other networks intrust on temporary connections that are established, maintained for a special period of time and then broken through rally or other forms of communication devices.

In general, the more permanent connections that pull round within a network the more smoothly that network will run. A network run entirely on temporary connections is subject to unwanted fragmentation: This tends to be the reference especially with telephone-line connections because they are constantly being called upon to be used for other functions at precisely that moment that a computer user wishes to employ them to carry data. The fewer temporary connections that experience within a network...
