### Main Content (50 minutes)
1. **Definition and Purpose of Networking (10 minutes)**
- Define what a computer network is.
- Explain its purpose, such as sharing resources, data, and improving communication.
2. **Types of Networks (15 minutes)**
- **Local Area Network (LAN)**
- Small geographic area, such as a single building.
- Common in homes, schools, and offices.
- **Wide Area Network (WAN)**
- Covers a large geographic area, such as cities, countries, or continents.
- The internet is a prime example.
- **Personal Area Network (PAN)**
- Very small network, typically used for connecting personal devices.
- Bluetooth and USB connections.
- **Metropolitan Area Network (MAN)**
- Covers a larger area than LAN but smaller than WAN.
- Often used in cities and regions.
3. **Networking Components (15 minutes)**
- **Router**
- Directs data from one network to another.
- **Switch**
- Connects devices within a single network.
- Manages data flow within the network.
- **Hub**
- Basic network device that connects multiple devices in a LAN.
- Unlike a switch, it does not manage data traffic.
- **Network Interface Card (NIC)**
- Hardware component that connects a computer to a network.
- **Modem**
- Converts digital data to analog signals and vice versa, enabling internet connectivity.
- Explain how these components work together to create a network.
4. **Network Topologies (10 minutes)**
- **Bus Topology**
- Single central cable to which all network devices connect.
- **Star Topology**
- All devices are connected to a central hub.
- **Ring Topology**
- Each device is connected to two other devices, forming a ring.
- **Mesh Topology**
- Devices are interconnected, with multiple pathways between them.
5. **Importance of Networking (10 minutes)**
- Enhance communication.
- Enable resource sharing.
- Facilitate centralized database management.
- Provide better security measures.

### Activities and Practice (15 minutes)
1. **Group Activity (10 minutes)**
- Divide the class into small groups.
- Each group creates a schematic representation of one type of network topology using markers and paper or a digital tool.
- Each group presents their topology and its key features.
2. **Q&A Session (5 minutes)**
- Open the floor for any questions or reflections on the lesson.
- Address any misunderstandings or provide further explanations as needed.

### Summary and Q&A (5 minutes)
1. **Recap the Lesson (3 minutes)**
- Summarize the key points covered:
- Definition and purpose of networking.
- Types of networks.
- Networking components.
- Network topologies.
- Importance of networking.
2. **Final Q&A (2 minutes)**
- Encourage students to ask any last questions.
- Provide clarifications where necessary.
**Homework Assignment:**
Research a real-world example of each type of network (LAN, WAN, PAN, MAN) and write a one-paragraph description for each, including how they are utilized in various settings.
