3. System Unit Components: The main box containing the core processing parts.
   1. Motherboard: The main circuit board connecting all components.
   2. Central Processing Unit (CPU): The “brain” of the computer, executing instructions.
   3. Random Access Memory (RAM): Temporary storage for active programs and data.
   4. Hard Disk Drive (HDD)/Solid State Drive (SSD): Permanent storage for files and operating system.
   5. Power Supply Unit (PSU): Converts AC power to DC power for the computer.

Introduction to GSM Repairs

GSM repairs involve diagnosing and fixing issues with mobile phones. Basic knowledge of phone components and safety is essential.

1. Basic GSM Repair Tools:
   1. Screwdriver set: For opening phone casings.
   2. Spudger/Pry tool: For safely separating components without damage.
   3. Tweezers: For handling small parts.
   4. Anti-static wrist strap: For preventing electrostatic discharge (ESD) damage.
2. Common Phone Components:
   1. Battery: Provides power to the phone.
   2. Screen (Display and Touchscreen): For visual output and user input.
   3. SIM Card Tray: Holds the Subscriber Identity Module card.
   4. Charging Port: For connecting the charger.
3. Safety Precautions in GSM Repairs:
   1. Always disconnect the battery before working on internal components.
   2. Use appropriate tools to avoid damaging the phone or injuring yourself.
   3. Work in a well-lit and clean environment.
   4. Handle delicate components with care, especially flex cables and connectors.

Teacher Guide for Using This Lesson Plan

Before the lesson, ensure you have any available computer hardware components (e.g., old mouse, keyboard, RAM stick) and basic phone repair tools for demonstration. Begin by engaging students in a quick recall of previous topics. Guide the revision through focused questions and exercises, allowing students to actively participate and clarify any doubts. Pay attention to common errors students made during the term and address them specifically. Encourage peer discussion and practical application where possible. The evaluation questions should directly assess the main concepts revised. Conclude by reiterating the importance of the revised topics for their understanding and future learning.
