Hardware components are physical parts of a computer system that work together to enable its functioning.
Here are some essential hardware components:

  • Central Processing Unit (CPU): The CPU is the "brain" of the computer, responsible for executing instructions and performing calculations.
  • Motherboard: The motherboard is the main circuit board that connects and allows communication between various hardware components.
  • Random Access Memory (RAM): RAM is a type of memory that temporarily stores data and instructions that the CPU needs to access quickly.
  • Hard Disk Drive (HDD) and Solid State Drive (SSD): These are storage devices that store the operating system, software, and user data.
  • Graphics Processing Unit (GPU): The GPU is dedicated to rendering and displaying images, making it crucial for gaming and graphics-intensive applications.
  • Power Supply Unit (PSU): The PSU supplies electrical power to all components of the computer.
  • Input and Output Devices: These include devices like keyboards, mice, monitors, printers, and speakers that allow users to input data and receive output from the computer.
  • Expansion Cards: These are optional components that can be added to enhance the computer's capabilities, such as graphics cards, sound cards, or network cards.
  • Cooling System: Computers often have fans or other cooling mechanisms to prevent overheating of the components.
