I. Provide a logical/physical design of the networked system with clear explanation and addressing table 1.1 The difference between logical and physical design
ļ¶ Logical Design:
ļ· A logical design is a conceptual, abstract design. You do not deal with the physical
implementation details yet; you deal only with defining the types of information
that you need. (Anon., n.d.)
ļ· The process of logical design involves arranging data into a series of logical
relationships called entities and attributes. An entity represents a chunk of
information. In relational databases, an entity often maps to a table. An attribute is
a component of an entity and helps define the uniqueness of the entity. In
relational databases, an attribute maps to a column.
ļ· You can create the logical design using a pen and paper, or you can use a design
tool such as Oracle Warehouse Builder or Oracle Designer.
ļ· While entity-relationship diagramming has traditionally been associated with
highly normalized models such as online transaction processing (OLTP)
applications, the technique is still useful in dimensional modeling. You just
approach it differently. In dimensional modeling, instead of seeking to discover
atomic units of information and all of the relationships between them, you try to
identify which information belongs to a central fact table(s) and which
information belongs to its associated dimension tables.
ļ¶ Physical Design:
ļ· My design networking system is an optimal networking system and matches the requirement
of the scenario.
ļ· The administrator can access all computers.
And the structure will be:
ļ· Two lab rooms is placed on floor 1 and 2.
ļ· In Background, weāll have 5 rooms, including: Server room, IT room, higher managers room,
marketing room and teacher room.
ļ· The D1 router is responsible as a main router to connect all the rooms in background to floor
1 and 2.
ļ· Others routers are connected to each other to Internet.
I.4 Physical design of network system Figure 2 : logical design of system
Explaination:
ļ· On first and second floor, Student have 25 computers and switch for each floor.
Figure 3 : First and second floor of system
ļ· The background floor will divided into 5 main rooms, including: 5 switches, 4 servers, 3
printers and 35 computers:
ļ· Server room: 4 servers and 1 switch.
Figure 4 : Server room
ļ· IT room: 3 computers.
Figure 5 : IT room
ļ· Marketing room: 12 computers and 1 printers.

ļ· Advantages:
ļ¼ If an error occurs in any part of the network, it will not affect the operation of
the rest of the network.
ļ¼ The size of the network can be easily expanded by adding new devices without
affecting the functionality of the existing network.
ļ¼ This topology is very flexible as it can be designed according to the
requirements of the organization.
ļ· Disadvantages:
ļ¼ The major limitation of the hybrid topology is the design of the hybrid
network. It is very difficult to design the architecture of a Hybrid network.
ļ¼ Infrastructure cost are very high because a hybrid network requires a lot of
equipments.
III. Implement a networked system based on a prepared design
