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?

Why ContentThe 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.

Concept of "Model"Types of network modelsStructure of TCP/IP and OSI models

The trainees should understand what is the protocol in general before we define types of protocols.

Explanation of "protocol".

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?

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.

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• 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.

Lesson Preparation

Lesson PlanI. General Information Topic: OSI model.Course Name and Code: Data

communication and Networks. BVF8.1Date and Time: 24/12/2012 From 8:30

To 9:10

Lesson PlanII. ObjectivesGeneral Learning Objectives:

• The Trainees: Should be able to write down the notes. Ask the question if they don’t understand. Write a small summary for the lesson.

• Specific Learning Objectives: The Trainees: Have to define what is the model. Should be able to define what is the protocol. Should be able to differentiates between OSI and

TCP/IP models. List the layers of OSI model. List some protocols and describe in which layer they

work.
