CONTENT OF THE LESSON

LESSON 1 – INTRODUCTION

MEANING OF NETWORK TOPOLOGY

Network topology is the arrangement and description of a computer network.

 

TYPES OF NETWORK TOPOLOGY 

Network topology is the way in which computers and other devices are connected in a network. It shows how data flows between devices. For example, in a school computer lab, the way all computers are connected to each other or to a server is known as network topology.

 

TYPES OF NETWORK TOPOLOGY 

The main types of network topology are,

1. Bus Topology

2. Star Topology

3. Ring Topology

4. Mesh Topology

5. Tree Topology

ASSIGNMENT – Find out the meaning of each type of network topology.

 

LESSON 2 – TYPES OF NETWORK TOPOLOGY

1. Bus Topology – This is so a network where all devices are connected to a single main cable (bus). Data travels in both directions along the bus.

Advantage – It is easy to set up and cheap.

Disadvantage – If the main cable fails, the whole network fails.

 

2. Star Topology – This is a network where all devices are connected to a central device (like a switch or hub). Data passes through the central device.

Advantage – It is easy to manage, failure of one device does not affect others.

Disadvantage – If the central hub fails, the whole network stops.

 

3. Ring Topology – This is network where the devices are connected in a circle or ring. Data travels in one direction around the ring.

Advantages – Data flows quickly, no collisions.

Disadvantages – If one device fails, the network may stop working.

 

4. Mesh Topology – This is where every device is connected to every other device.

Advantages – Very reliable, if one connection fails, data can take another path.

Disadvantages – Expensive and complicated to set up.

 

5. Tree Topology – This is a combination of star and bus topologies. In this network, groups of star networks are connected to a main bus.

Advantages – Scalable and easy to manage.

Disadvantages – If the main bus fails, parts of the network may stop.

 

LESSON 3 – REVISION AND WEEKLY ASSESSMENT (TEST)

Revision – Network topology is how devices are connected. Common types include Bus, Star, Ring, Mesh, and Tree. Each topology has advantages and disadvantages.

Weekly Assessment – As state in the lesson objectives or evaluation.

Assignment – Find out the advantages and disadvantages of computer network.

 

PRESENTATION

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

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

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

3. If available, teacher uses functional computers to demonstrate network topology. But if not, Tecaher displays charts showing types of network topology.

4. Teacher lets pupils identify and differentiate each of the network based on the arrangement.

Pupil’s Activities –

5. Teacher uses the chart/functional computers and the pupils relevant responses to introduce and explain each type of topology.

Pupil’s Activities –

6. Teacher leads the pupils to identify and discuss the advantages and disadvantages of each network topology.

7. 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 and links it to the following week’s lesson.

Next Lesson – Advantages and Disadvantages of Computer Network | Uses of Computer Network Primary 6 (Basic 6) Term 2 Week 6 Information Technology

 

LESSON EVALUATION
