+## Components of a Computer
+
+1. **CPU**: Central Processing Unit - The "brain" of the computer that performs calculations and logic operations.
+2. **RAM**: Random Access Memory - Temporary data storage that is faster to read and write compared to hard drives.
+3. **Hard Drive**: Long-term data storage, can be HDD or SSD.
+4. **Motherboard**: The main circuit board connecting all components.
+5. **Power Supply**: Converts electrical power to a format suitable for the computer.
+6. **GPU**: Graphics Processing Unit - Handles rendering images and videos.
+7. **Input Devices**: Devices like keyboards, mice, and scanners for user input.
+8. **Output Devices**: Devices like monitors, printers, and speakers for displaying output.
+9. **Cooling System**: Fans or liquid cooling to maintain optimal temperature.
+10. **Case**: Houses and protects the components.
