A computer tower has several key components that are essential for working and can all be recycled when it has become obsolete.

1. Motherboard: The main circuit board that connects and allows communication between various components, including the CPU, memory, storage devices, and peripheral devices.
2. Central Processing Unit (CPU): The primary component that manages as a control center that runs the towers operating system and apps.
3. Memory (RAM): Random Access Memory provides temporary storage for data and instructions that the CPU is actively using.
4. Storage Devices:
   • Hard Disk Drive (HDD): A traditional storage device that uses magnetic storage to store data.
   • Solid State Drive (SSD): A faster and more modern storage device that uses flash memory for data storage.
     • • Flash Memory: Can keep data and information when the system is powered off.
5. Power Supply Unit (PSU): Converts electrical power from an outlet into a usable form for the computer’s components.
6. Expansion Slots: Slots on the motherboard for adding additional hardware components such as graphics cards, sound cards, or network cards.
7. Graphics Processing Unit (GPU): Also known as a graphics card, it is responsible for rendering images and videos.
8. Cooling System:
   • Fans: Help dissipate heat generated by the CPU, GPU, and other components.
   • Heat Sink: A metal component that absorbs and disperses heat, often attached to the CPU.
9. Optical Drive: A drive for reading and writing optical discs such as CDs, DVDs, or Blu-ray discs
10. Cables and Wiring: Various cables connect components inside the tower, ensuring data and power transmission.
