    Study Notes

    Main Components of Computer Systems

    • Computer systems comprise hardware (physical parts) and software (intangible programs).

    Hardware

    • Input Devices: Allow users to enter data (e.g., keyboard, mouse).
    • Output Devices: Display or present data (e.g., monitor, printer, speaker).

    Central Processing Unit (CPU)

    • Acts as the "brain" of the computer, executing instructions and managing resources.

    Graphics Processing Unit (GPU)

    • Specialized for rapid image and video data processing; ideal for parallel tasks like 3D rendering.

    CPU vs. GPU

    • CPU: General-purpose, aligns with sequential processing; handles diverse applications but less efficient for parallel tasks.
    • GPU: Excels at tasks suited for parallel processing; great for graphics and machine learning but primarily designed for graphics-related functions.

    Advantages and Disadvantages

    • CPU Advantages: Versatile, can perform a wide range of tasks.
    • CPU Disadvantages: Less efficient in parallel processing; may consume more power.
    • GPU Advantages: Highly efficient for parallel tasks and energy-efficient in specific workloads.
    • GPU Disadvantages: Generally costly and programming complexity increases when utilizing GPUs.

    Motherboard

    • The main circuit board connecting all computer components.

    Primary Storage Devices

    • RAM (Random Access Memory): Temporary storage for data and instructions.
    • ROM (Read-Only Memory): Permanent storage for critical system software.

    Secondary Storage Devices

    • HDD (Hard Disk Drive): Magnetic data storage.
    • SSD (Solid-State Drive): Fast, reliable flash memory storage.
    • M.2 SSD: Compact SSD form factor, commonly in laptops.
    • Floppy Disk: Obsolete medium for removable data storage.
    • Optical Drive: Reads/writes data to CDs/DVDs/Blu-ray.
    • Flash Drive: Portable storage for data transfer and access.

    Power Supply Unit (PSU)

    • Converts AC power to DC power for computer components.

    Cooling System

    • Maintains optimal operating temperature using fans and heat sinks; thermal paste is utilized for improved heat transfer.

    Networking Devices

    • Include Network Interface Card (NIC), Wireless Card, and Wi-Fi Stick for connectivity.

    Input/Output Ports

    • USB Ports: Connect various devices.
    • HDMI Ports: High-quality video and audio output.
    • DisplayPort: Digital video interface for display connections.
    • VGA: Older analog video interface for display connections.
    • Ethernet: Establishes connections to wired networks.
    • Audio Ports: Color-coded ports for microphones, speakers, and headphones.

    Internal Ports

    • PCI: Expansion slot for connecting devices like network and sound cards.
    • PCIe: High-speed expansion slot for performance devices like GPUs and SSDs.
    • SATA: Connects storage devices (HDDs and SSDs).
    • PS/2: Older port for keyboards and mice.
    • CMOS Battery: Powers CMOS memory for BIOS settings.

    Software

    • Divided into two categories:
      • System Software: Manages basic computer operations (e.g., operating systems like Windows, macOS).
      • Application Software: Designed for specific user tasks (e.g., word processors, games).

    System Software Examples

    • BIOS (Basic Input/Output System): Firmware stored on the motherboard chip, crucial for system startup and management.
