Content
Explanation of the Topic
- CPU (Central Processing Unit):
- Definition: The CPU is the brain of the computer. It processes instructions and performs calculations.
- Features of the CPU:
- Processor:
- Function: Executes instructions from programs and applications.
- Identification: Small, square chip with many tiny pins.
- Core:
- Function: The part of the CPU that reads and executes instructions. More cores can mean better performance.
- Identification: Inside the processor, usually not visible, but can be understood as part of the processor.
- Heat Sink:
- Function: Keeps the CPU cool by dissipating heat.
- Identification: Metal piece with fins, often attached to the top of the CPU.
- Clock Speed:
- Function: Measures how fast the CPU can process instructions. Measured in GHz (Gigahertz).
- Identification: Usually written in the specifications of the CPU, not a physical part.
- Memory (Cache):
- Function: Stores frequently used data for quick access by the CPU.
- Identification: Small part within the CPU, not visible, but can be understood as a feature of the CPU.

Presentation
Step 1
The teacher revises the previous topic, which was “Types of Computers: Analogue, Digital, and Hybrid.”
Step 2
The teacher introduces the new topic, “Features of the CPU and Their Functions.”
Step 3
The teacher allows the pupils to give their own contributions and corrects them when and where necessary.
Teacher’s Activities
- Ask questions about what the pupils know about the CPU.
- Show diagrams and real CPU components.
- Explain the functions of each feature of the CPU.
- Correct pupils’ answers and provide further explanations.
Learners Activities
