OSI model

Content analysis Meshal 202322421 Faisal 202322420

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? 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. Concept of "Model" Types of network models Structure 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.   Application layer Presentation layer Session layer Transport layer Network layer Data Link layer Physical layer

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.

4-What media do have? Used Media Yes Whiteboard Power point No Smart board Handout Poster Mind map

Curriculum analysis 202322427 Mansour Ali

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 Mashal 202322421

Lesson Plan I. General Information Topic: OSI model. Course Name and Code: Data communication and Networks. BVF8.1 Date and Time: 24/12/2012 From 8:30 To 9:10

Lesson Plan II. Objectives The Trainees: Specific Learning Objectives: General 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: 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.
