2. Meaning of Network Topology

3. Types of Network Topology

4. Stretch Different Types of Network Topology

 

PERFORMANCE OBJECTIVES

By the end of the lesson, most of the pupils should have attained the following objectives –

1. define computer topology correctly.

2. explain the meaning of network topology in simple terms.

3. identify the different types of computer topology.

4. eescribe the structure and layout of each type of topology.

5. state at least two examples where each topology is commonly used.

 

ENTRY BEHAVIOR

The pupils can state the requirements for computer network.

 

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of charts of network topology.

 

 

CONTENT OF THE LESSON

LESSON 1 – INTRODUCTION

Network Topology is the way computers are connected to each other in a network. It shows how computers and other devices like printers or servers are linked together so they can share information.

 

TYPES OF NETWORK TOPOLOGY 

Network topologies define how devices connect, with common types including –

1. Star Topology

2. Bus Topology

3. Ring Topology

4. Mesh Topology

5. Tree Topology

6. Hybrid Topology

ASSIGNMENT – With the aid of diagram, find out the meaning of each type of network topology.

 

LESSON 2 – TYPES OF NETWORK TOPOLOGY 

1. Point to Point Topology – Point to point topology is a network where two or more computer are connected to one another direct in a line. It is a direct connection two devices.

2. Star Topology – Star topology is a network where all computers are connected to one central device (like a hub or switch). Data goes through the central device to reach other computers. For example, school computer lab.

3. Bus Topology – Bus topology is a network where all computers are connected to one main cable (like a bus route). Data travels in both directions along the cable. It is used in a small office.

4. Ring Topology – Ring topology is a network where all computers are connected in a circle. Data travels in one direction around the circle until it reaches the correct computer. For example, some office networks.

5. Mesh Topology – Mesh topology is a network where each computer is connected to all the other computers. That’s, the computers are interconnected with one another. They are very reliable, but uses a lot of cables. For example, large company networks.

6. Tree Topology – Tree topology is a network where all computers are connected in a branch structure that looks like a tree. They combines star and bus topologies. A good examples is large schools or organizations.

7. Hybrid Topology – Hybrid Topology is a network where there a mix of two or more topologies. For example, a company using both star and bus networks together.

LESSON 3 – SUMMARY, REVISION AND WEEKLY ASSESSMENT (TEST)

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. Teacher revises the previous lesson based on the pupil’s related knowledge or experience.

2. Teacher organizes the pupils in groups depending on the size of the class or available computers.

3. Teacher displays charts showing a point to point, star, bus, ring or circle and also, chart showing different types of network topology for the pupils to identify, match and explain based on their homework.

4. Teacher leads and guides the pupils to identify and differentiate between each of the network topology.

Pupil’s Activities – The pupils identify and differentiate between each of the network topology.

5. Teacher uses the displayed chart, avaliable computers and the pupils relevant responses to introduce the lesson, explain the meaning and state the types of network topology.

Pupil’s Activities – The pupils pay attention to the lesson introduction, understand and explain the meaning and types of network topology in their own term.

6. Tecaher summarize Lesson 1 on the board and gives the pupils individual or group assignments.

Pupil’s Activities – The pupils participate actively in the summary of the lesson by responding correctly to most of the questions write as instructed.

7. Tecaher uses the chart to lead and guide the pupils to explain and differentiate between each types of network topology.

Pupil’s Activities – The pupils understand and appreciate the meaning and types of network topology.

8. Teacher summarizes the lesson on the board with appropriate evaluation.

Pupil’s Activities – The pupils participate actively in the summary of the lesson by responding correctly to most of the questions write as instructed.

 

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson (Network Topology is how computers are connected to share information. There are different types of network topology – line: Point to point, Bus: One main, cable, Star: Central hub, Ring: Circle, Mesh: Everyone connected, Tree: Branching like a tree and Hybrid: Mix of  types) and links it to the following week’s lesson. Network Topology 

Next Lesson – Advantages and Disadvantages of Computer Network Primary 6 (Basic 6) – Computer Studies

 

LESSON EVALUATION

Teacher asks pupils to – 

1. explain the meaning of network topology in simple terms.

2. with the aid of diagram, differentiate each type of computer topology.

3. state at least two examples where each topology is commonly used.
