The physical components of a computer are collectively known as hardware.

This encompasses all the tangible parts you can physically touch, such as:

• Central Processing Unit (CPU): Often referred to as the "brain" of the computer, responsible for executing instructions. Source

• Random Access Memory (RAM): Used for short-term data storage that the CPU accesses quickly. Source

• Hard Disk Drive (HDD) or Solid State Drive (SSD): Used for long-term data storage. Source

• Motherboard: The main circuit board that connects all the components. Source

• Graphics Card (GPU): Processes and outputs images to the display. Source

• Power Supply Unit (PSU): Provides power to all the components. Source

• Input Devices: Devices used to input data into the computer (e.g., keyboard, mouse). Source

• Output Devices: Devices used to output data from the computer (e.g., monitor, printer). Source
