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).
