    Study Notes

    Occupational Health and Safety (OHS) Standards

    • OHS is a framework ensuring worker well-being, safety, and protection in various environments.
    • OHS standards in Computer System Servicing (CSS) ensure individuals are adequately protected from potential hazards.
    • Standards cover personal protective equipment (PPE), safety protocols, and hazard-free work areas.

    Essential Protective Equipment

    • Gloves: Protect hands from cuts, abrasions, and chemical burns.
      • Types include nitrile, latex (flexible and sensitive), and leather (protection from mechanical hazards).
    • Eye Protection: Safeguards eyes from debris, splashes, and radiation.
      • Types include safety goggles (full eye coverage), and face shields (extended face and eye protection).
    • Hearing Protection: Prevents hearing damage from loud noise.
      • Types include earplugs (inserted into the ear canal), and earmuffs (covering the entire ear).
    • Anti-static Equipment: Prevents electrostatic discharge (ESD), protecting sensitive electronic components.
      • Types include anti-static wrist straps, anti-static mats, and grounding devices.

    Applications in Computer System Servicing (CSS)

    • CSS tasks expose workers to electrical, physical, and chemical hazards.
    • Key practices include ensuring proper grounding during hardware handling.

    Core Principles of OHS Standards

    • Risk Assessment: Identifying and evaluating potential workplace hazards and implementing measures to mitigate risks.
    • Safety Training: Educating workers on proper PPE use and safety protocols.
    • Workplace Maintenance: Maintaining a clean, organized environment free of hazards.
    • Emergency Preparedness: Establishing procedures for emergencies, like fire, medical, and other crises.
    • Legal Compliance: Adhering to governmental OHS regulations and standards, properly documenting activities.

    Computer Architecture and Function

    • CPU (Central Processing Unit): The "brain" of the computer, interpreting and executing instructions, acting as the main control unit.
    • ALU (Arithmetic Logic Unit): Performs arithmetic and logical operations.
    • Registers: Temporary, high-speed storage holding data during processing.
    • Cache: High-speed memory storing frequently accessed data for reduced latency.
    • Clock: Synchronizes CPU operations, defining the number of cycles the CPU performs per second.
    • Buses: Electrical pathways for data transmission between CPU components.

    RAM (Random Access Memory)

    • Provides temporary storage for operating systems, software, and data in use.
    • Ensures quick access for the processor, enhancing system performance.
    • Key features include clock speed, and frequency.
    • Types include FPM, EDO, and SDRAM (Synchronous DRAM)

    Motherboard Components

    • CPU Socket: Holds the CPU in place.
    • Chipsets: Manage communication between CPU and other motherboard components (split into Northbridge and Southbridge).
    • Memory Slots (DIMM): Hold RAM modules.
