Difference between Logical & Physical Design of a Network
When we look at the differences between logical design and physical design of a network it is easy to think of it as the logical as the functional part and physical as the seeing it part. With that stated there is more to this than just the functional and seeing parts. In order to understand the differences from one to the other, we need more information. In the following paragraphs I will try to outline what makes up the differences between logical and physical design of a network.
So let's first look at what constitutes a logical design of a network. The first thing we know is that the logical design is, "The part of the design phase of the SDLC in which all functional features of the network chose for development are described independently of any computer platform." There are other ways to describe a logical network, but the one that comes to mind is how the network will be structured. Basically we are talking about all of the logical aspects of the network. According to Webopedia, "the logical topology is the way the data passes through the network from one device to the next without regard to physical interconnection of the devices." Also the logical design lacks specific details such as technologies and standards and focuses on the general needs of the network. A logical design can be a view of any part of the network, whether it be the whole or just a part of it. Another element of the logical design is the IP addresses and their association with the different parts of the network. The IP addresses are assign to devices such as routers, switches, servers, workstations, and other devices that utilize the network. In the logical design we usually do not show the actual interfaces and physical cables in the diagrams; thus giving us the true meaning of the term "logical." IP structure is a big part of the logical design of a network as well as security planning. A good logical design will have...
