1. Central Processing Unit (CPU): The CPU is the brain of the computer that performs all the processing tasks, such as executing instructions and performing calculations.

2. Random Access Memory (RAM): RAM is the temporary storage space where data and instructions are stored while the computer is running. It allows for quick access to data and programs.

3. Hard Drive: The hard drive is the permanent storage space where all data, programs, and operating system files are stored. It retains data even when the computer is turned off.

4. Motherboard: The motherboard is the main circuit board of the computer that connects all the components together. It houses the CPU, RAM, and other essential components.

5. Graphics Processing Unit (GPU): The GPU is responsible for rendering graphics and images on the computer screen. It is essential for tasks such as gaming, video editing, and graphic design.

6. Power Supply Unit (PSU): The PSU provides power to all the components of the computer. It converts electricity from the wall outlet into the appropriate voltage needed by the computer.

7. Input and Output Devices: These include devices such as keyboards, mice, monitors, printers, and speakers that allow users to interact with the computer and receive output.

8. Cooling System: The cooling system, which includes fans and heat sinks, helps to regulate the temperature of the computer components and prevent overheating.

9. Operating System: The operating system is the software that manages the computer's hardware and provides a user interface for interacting with the computer. Examples include Windows, macOS, and Linux.
