4. Storage Devices (HDD, SSD)
- Description: Devices that store data, files, and applications.
- Types:
- HDD: Hard Disk Drive, traditional storage with larger capacity.
- SSD: Solid State Drive, faster but generally more expensive.
Storage devices are where all your files, software, and operating system reside. SSDs are faster than HDDs, making them ideal for a quicker computing experience.

7. Input Devices
- Description: Tools that allow users to interact with the computer.
- Examples: Keyboard, mouse, scanner, microphone.
Input devices are essential for user interaction, allowing us to communicate commands and information to the computer.
Image Suggestion: Keyboard, mouse, and microphone setup.
8. Output Devices
- Description: Devices that display or deliver information from the computer.
- Examples: Monitor, printer, speakers.
Output devices show us the results of our tasks, whether through visual, audio, or printed means. High-quality output devices improve the user experience.
Image Suggestion: Monitor setup with speakers.
9. Software Components
- Operating System (OS): Manages hardware and provides an interface for users. Examples include Windows, macOS, and Linux.
- Application Software: Programs for tasks like word processing, design, or gaming.
- Drivers: Software that ensures hardware components work with the OS.
Software plays a crucial role in making hardware usable. It manages resources, runs applications, and allows users to interact with the computer.

Key Points to Remember
- All Components Work Together: The CPU, motherboard, RAM, and storage devices are essential for a functional computer.
- Power and Compatibility Matter: The PSU and motherboard ensure stable power and connectivity between parts.
- Software Complements Hardware: An OS and application software bring hardware to life, making it accessible to users.
Frequently Asked Questions (FAQs)
Q1: What’s the difference between RAM and storage?
Answer: RAM is temporary memory for active tasks, while storage (HDD or SSD) holds files and applications permanently.
Q2: How important is the motherboard in a computer?
Answer: The motherboard connects all parts, determines compatibility, and ensures communication between components.
Q3: Why do some computers have both HDD and SSD?
Answer: Using both allows for a balance between storage capacity (HDD) and speed (SSD), with the SSD typically holding the OS and essential files.
Q4: Is a dedicated GPU necessary for all users?
Answer: No, a dedicated GPU is primarily needed for gaming, video editing, and graphics-intensive tasks. For basic use, integrated graphics are sufficient.
Q5: How often should I upgrade my CPU?
Answer: Upgrading every 3-5 years is common, but it depends on your needs and performance expectations.
