floppy disk and physically walking it over (or mailing it) to another processing unit. However, as technology improved, so did methods of sharing information and data. These days, instead of
relying on floppies to get information from computer A to computer B, most people are connected to some kind of network that is connected via solid physical and logical designs,
or architectures. In this paper, well examine the concepts of physical and logical design, and describe a network that has used these designs.
Physical designs, in their most basic form, demonstrate how the network elements connect with one another, especially in terms of physical characteristics (which include, but arent limited to bandwidth, manufacturer
of the network, ports, connectors and so on). The physical design is a roadmap - while connecting two computers is a fairly easy process, connecting many computers to the same
network requires a little more information (Cardiff University, 2003). The main methods of connection through physical design are star, hierarchical and loop
configurations and bus and ring configurations (Cardiff University, 2003). Star, hierarchical and loop configurations are classified as point-to-point topologies; a system by which each computer connect directly with its neighboring
computer (Cardiff University, 2003). These configurations rely on the network "neighborhood" for relay of data as well (Cardiff University, 2003). The problem with such protocols, however, lies with the main
computer - if that should go down, or fail, this can disable the network (Cardiff University, 2003). Then there are the bus and
ring topologies, known as broadcast technologies, as they dont necessarily need a prime computer (but they do need protocols) (Cardiff University, 2003). In these particular configurations, a message containing the
