A computer system is composed of several key components that work together to perform various tasks. Here are the main components of a typical computer system:

  1. Central Processing Unit (CPU): Also known as the processor, the CPU is the brain of the computer. It executes instructions, performs calculations, and manages the overall operation of the computer.
  2. Memory (RAM): Random Access Memory (RAM) is temporary storage that the CPU uses to store data and instructions that are currently being used. It allows for quick access to data, but it is volatile, meaning it loses its contents when the computer is turned off.
  3. Storage Devices: Storage devices are used to store data and programs permanently. Examples include hard disk drives (HDDs), solid-state drives (SSDs), and optical drives (such as CD/DVD drives).
  4. Motherboard: The motherboard is the main circuit board of the computer. It provides connections for other components, such as the CPU, memory, storage devices, and expansion cards.
  5. Input Devices: Input devices allow users to interact with the computer and input data. Examples include keyboards, mice, touchscreens, and scanners.
  6. Output Devices: Output devices display or present information processed by the computer. Common output devices include monitors, printers, and speakers.
  7. Graphics Processing Unit (GPU): The GPU is responsible for rendering graphics and images. It offloads graphical processing tasks from the CPU, improving overall performance, especially in tasks such as gaming and video editing.
  8. Power Supply Unit (PSU): The PSU converts electrical power from an outlet into usable power for the computer’s components. It provides power to the motherboard, CPU, and other devices.
  9. Expansion Cards: Expansion cards are used to add additional functionality to a computer system. Examples include graphics cards, network interface cards (NICs), and sound cards.
  10. Operating System (OS): The operating system is software that manages hardware resources and provides a user interface for interacting with the computer. Common operating systems include Windows, macOS, and Linux.

These components work together to process data, run programs, and perform various tasks, making the computer system functional and useful for users.
