    • Subject: Technology and Livelihood Education (TLE)
    • Module: Quarter 2, Module 1, Types of Components and Objects to be Measured
    • Government Property: Material is not for sale
    • Curriculum: K to 12, using the Most Essential Learning Competencies (MELC)
    • Learning Resources: Self-Learning Modules, online resources, and various storage devices
    • Learning Competencies: Communication, Collaboration, Creativity, Critical Thinking, Character
    • Target Audience: Learners guided by educators
    • Learning Goal: Understanding the types of computer components and measuring their objects, appreciating the importance of knowing them.

    Types of Components and Objects

    • Memory (RAM): Temporary storage of instructions and data, volatile (lost when power is off).

      • Measured in Megabytes (MB) and Gigabytes (GB)
    • Read-Only Memory (ROM): Non-volatile, data remains even without power. Used for firmware.

    • Data Storage Capacity: Measures the capacity of data storage devices.

      • Measured in Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB)
    • Magnetic Storage: Stores data magnetically in tiny dots.

      • Hard Drives: High capacity, random access for large files like videos.
      • Portable Hard Drives: External storage, connected via USB
      • Magnetic Tapes: Thin, magnetizable coating on a plastic strip
    • Optical Storage: Stores data optically.

      • Compact Discs (CDs, CD-ROMs): Read-only, holds around 800MB.
      • Digital Versatile Discs (DVDs, DVD-ROMs): 4.7 GB of data. Used for high-quality video.
      • Blu-ray Discs: High-capacity, up to 25-50 GB. Replacement for DVDs.
      • High-Density DVDs: Holds around 15 GB
    • Solid-State Storage: No moving parts. Stores data using flash memory.

      • Memory sticks / Thumb drives / Flash drives: Portable, non-volatile.
      • Smart cards: Plastic cards with microchip. Often used for access control, etc.
    • Processor (CPU): The "brain" of the computer, executing instructions. Speed is measured in Hertz (Hz), typically GHz.

    • Video Card: Enhances image quality, used for display. Performance measured in Frames Per Second (FPS).
