1-What is OSI?
• The Open Systems Interconnection Basic Reference
Model (OSI Model) is an abstract description for
network protocol design, developed as an effort to
standardize networking.
• There are many protocols are used in OSI model
which divided into seven layers each layer has
special protocols.
2-Why are these contents related
for the trainees?
Content
Why
Concept of "Model"
Types of network models
Structure of TCP/IP and OSI models
The trainees should know concept of
"model" before starting to explain the
types of models, and see the difference
between types of models, and understand
the structure of these models because, the
trainees must understand the structure
before we go deeper in protocols.
Explanation of "protocol".
The trainees should understand what is
the protocol in general before we define
types of protocols.
The trainees should know the OSI model
division and the differences between
TCP/IP and OSI models in the division.
Division of OSI model.
2-Why are these contents related
for the trainees?
Application layer
Presentation layer
Session layer
Transport layer
Network layer
Data Link layer
Physical layer
The trainees should understand each layer
independently and understand what
protocols are working in this layer such as:
- Application layer: DNS, DHCP, FTP
….etc.
- Presentation layer: Responsible for
encryption.
Session: Open and close Ports.
- Transport layer: TCP and UDP.
- Network: Guide the packet entire the
network.
- Data Link: Communicating with MAC
addresses and transmits frames.
-Physical: Using signals.
3- What kind of prior this knowledge do the trainees
have to have in order to understand this topic?
• The trainees should have the following prior
knowledge:
• To have basic information about Networking in
general.
• To have known some information about packet
switching and circuit switching.
• To have idea about protocols in general.
Didactic analysis
Why the OSI model important?
• The OSI model has importance; it's like standards
which help anybody wants to study the networking.
• For my trainees they should understand OSI model
because it helps them in next courses such as:
switching and routing.
What are my intentions?
(General objectives)
Make a creative thinking.
Try to make sure the practical is clear for
students.
Motivate trainees to do group work.
3-How can we integrate practical sequences?
(Theory-Practical-Relation)
• In our lesson there is no practical, but we will try to
deliver the concept of our lesson by doing
experiment in front of the class. We will make
demonstration using Wireshark application which is
one of greatest network analysis programs round the
world. The trainees will see how the OSI model works
then they will be able to understand our lesson.

Curriculum analysis
Curriculum analysis
• The topic belong to the course: Data
Communications and Networks (ICT-BVF 8.1).
• Today the topic will deal with "Explain OSI model".
• Explain the layers (1) Application, (2) Presentation,
(3) Session, (4) Transport, (5) Network, (6) Data Link,
(7) Physical
• We plan to spend 50 minutes on this topic.
• It is take a place in second semester of TTC.
• The students have to know the basic information of
basic networks and communications.
Curriculum analysis
* This course depends on what the students
learned in previous lessons in the same
course, because if the students did not have
an idea about packet switching and circuit
switching then they will not understand this
lesson.
