Full List of Basic Computer Parts & What They Do

Computer parts are the essential components that make up a computer system. These hardware components work together to enable the functioning of a computer. Here is a comprehensive list of common computer parts and a brief description of their functions:


  • 1. Central Processing Unit (CPU): Also known as the "brain" of the computer, the CPU processes data and performs calculations.
  • 2. Graphics Processing Unit (GPU): The GPU is responsible for rendering and displaying graphics, making it crucial for gaming and graphic design.
  • 3. Random Access Memory (RAM): RAM stores data temporarily for quick access by the CPU, enhancing the computer's performance.
  • 4. Hard Disk Drive (HDD): The HDD is a storage device that stores the computer's operating system, software, and files.
  • 5. Solid State Drive (SSD): Similar to an HDD, an SSD is a faster and more reliable storage device that improves overall system performance.
  • 6. Motherboard: The motherboard is a circuit board that connects and allows communication between various computer components.
  • 7. Power Supply Unit (PSU): The PSU supplies electrical power to all components of the computer.
  • 8. Computer Case: The computer case houses and protects all internal components, ensuring proper cooling and preventing damage.

Peripherals are external hardware components that enhance computer functionality. Common peripherals include monitors, keyboards, mice, speakers, printers, and scanners. Understanding these computer parts and their functions is vital in building, upgrading, and maintaining computer systems.


What are Internal Computer Hardware Components?

Internal computer hardware components are the essential parts that work together to make a computer function. The motherboard, also known as the mainboard, serves as the central hub connecting all other components. It houses the CPU (central processing unit), which acts as the brain of the computer, executing instructions and performing calculations. The CPU's speed and capabilities, known as clock speed, directly affect a computer's performance. The RAM (random access memory) stores data that the CPU needs to access quickly. It acts as a temporary workspace, allowing for quick data retrieval and processing. The hard drive, on the other hand, provides long-term storage for files, applications, and the operating system. It retains data even when the computer is turned off. Another crucial component is the GPU (graphics processing unit), responsible for rendering visuals and graphics-intensive tasks. It works in tandem with the CPU to handle graphics processing efficiently, crucial for gaming, video editing, and graphic design.


These internal components are the backbone of any modern computer, and the performance and capabilities of each directly impact the overall computing experience. By understanding the functions and importance of these components, users can make informed decisions when choosing or upgrading their internal computer hardware components.
