1) The difference between the logical and the physical design:
1.1) Physical Topology:
- Physical topology indicates arrangement of different elements of a network. It reflects physical layout of
devices and cables to a form a connected network. It is concerned with essentials of network ignoring
Downloaded by Tran Huu Hoang Tuan (FGW HCM) (tuanthhgcs230462@fpt.edu.vn)
lOMoARcPSD|40084550
minute details like transfer of data and device type. The pattern of arrangement of nodes (computers)
and network cables depends on ease of installation and setup of the network. It affects cost and
bandwidth capacity based on solution of devices. It takes into account placement of nodes and distance
between them. Devices can be arranged to form a ring (Ring Topology) or linearly connected in a line
called Bus Topology.
1.2) Logical Topology:
- Logical Topology reflects arrangement of devices and their communication. It is the transmission of data
over physical topology. It is independent of physical topology, irrespective of arrangements of nodes. It is
concerned with intricate details of network like type of devices (switches, routers) chosen and their
quality, which affect rate and speed of data packets delivery. The logical topology ensures optimal flow
control that can be regulated within network. The data can either flow in a linear pattern called Logical
bus or in form of a circle Logical ring.
1.3) The difference between logical and physical design:
- Logical layout of a network can be defined as the mode of communication that connects two computers
connected to a network. Logical layout consists of the outflow of data between two systems. In actual
sense network connectivity is based on logical design of a network. The physical layout design is installed
using logical design.
- The logical network can also be upgraded and can be used to connect two or more computers together.
Logical design of a network consists of virtual design while the physical design of a network describes the
hardware functions of the network. Logical designs determine the flow of data or communication
between two networks while physical design is a communication between two computers connected with
cables.
- For example, a physical design of a network can be upgraded to link two or three office buildings. The
expansion would require an upgrade using logical design layout of a network. This would make it easy for
information to be processed from any system in buildings at the same time.
- Physical layout of a network is based on a logical layout. For example, an organization that installs a wide
area network would be drawn as a single line diagram; this is a basic design of a physical layout. Thus, the
explanation it means that logical design of a network can be developed or expanded using physical design
while retaining its original characteristics.

2) Evaluate the design of the network:
- My design of the network is still not perfect. There are some limitations in the networked system:


The server room is not clearly located
The IP addresses of the system and the PCs are confusing and easy to misunderstand.
- However, my design also has some advantages:




The networked system is divided clearly into three different floors: ground floor, first floor, and
second floor.
The design has met the requirements of the manager: enough 35 staff PCs (include 3 admin PCs),
50 student PCs, and 3 printers.
The server room is separated from the PCs room for simpler maintenance and improvement
The network layout has been effectively indicated with clearly explanations
