Computer parts and their functions

                                                                    

     

1. 1. Central Processing Unit (CPU):

   • Function: Often referred to as the brain of the computer, the CPU performs calculations and executes instructions from the computer's memory.

2. 
   

3. 2. Motherboard:

   • Function: The motherboard is the main circuit board that connects all the components of the computer, allowing them to communicate with each other.

4. 
   

5. 3. Random Access Memory (RAM):

   • Function: RAM is volatile memory used by the computer to store data that is actively being used or processed. It provides fast access to data for the CPU.

6. 
   

7. 4. Storage Devices (Hard Drive, SSD):

   • Function: Hard drives and solid-state drives (SSDs) are used for long-term storage of data, applications, and the operating system. SSDs are faster than traditional hard drives.

8. 
   

9. 5. Graphics Processing Unit (GPU):

   • Function: The GPU is responsible for rendering images and videos. It is crucial for graphics-intensive tasks such as gaming, video editing, and 3D rendering.

10. 
    

11. 6. Power Supply Unit (PSU):

    • Function: The PSU provides power to the components of the computer. It converts electrical power from an outlet into a form that the computer can use.

12. 
    

13. 7. Cooling System:

    • Function: Computers generate heat, especially the CPU and GPU. Cooling systems, such as fans or liquid cooling, help dissipate this heat to prevent components from overheating.

14. 
    

15. 8. Input Devices (Keyboard, Mouse):

    • Function: Input devices allow users to interact with the computer. Keyboards are used for typing, while mice or touchpads are used for navigating and selecting items.

16. 
    

17. 9. Output Devices (Monitor, Printer):

    • Function: Output devices display information from the computer. Monitors show visual output, while printers produce hard copies of documents.

18. 
    

19. 10. Network Interface Card (NIC):

    • Function: The NIC enables the computer to connect to a network, either wired (Ethernet) or wireless (Wi-Fi), allowing it to communicate with other devices.

20. 
    

21. 11. Expansion Cards (e.g., Graphics Card, Sound Card):

    • Function: These cards can be added to the motherboard to enhance specific capabilities, such as improved graphics or audio performance.

22. 
    

23. 12. Peripheral Devices (External Drives, USB Devices):

    • Function: Peripheral devices connect to the computer to provide additional functionality, such as external storage or input devices.
