    • Modern CPU s can have multiple cores, allowing them to execute multiple tasks simultaneously.
  2. Motherboard:
    • The motherboard is the main circuit board of the computer, connecting all other components.
    • It houses the CPU, RAM, and other essential components and provides the connections for various peripherals.
  3. Random Access Memory (RAM):
    • RAM is the computer’s primary memory, used to temporarily store data and instructions that the CPU needs for immediate processing.
    • The amount of RAM affects the computer’s performance, as more RAM allows for smoother multitasking.
  4. Storage Devices:
    • Hard Disk Drive (HDD): HDD s use spinning disks to store data magnetically. They offer large storage capacities but are relatively slower than SSD s.
    • Solid State Drive (SSD): SS D s use flash memory to store data. They are faster, more durable, and energy-efficient compared to HDD s.
  5. Power Supply Unit (PS U):
    • The PS U provides electrical power to all components of the computer. It converts AC power from an outlet into DC power that the computer can use.
  6. Graphics Processing Unit (GPU):
    • The GPU, also known as a graphics card, is responsible for rendering images and videos. It is essential for gaming and graphic-intensive applications.
    • Some CPU s have integrated graphics, while others require a dedicated GPU.
  7. Input and Output (I/O) Devices:
    • Input devices include the keyboard, mouse, touch pad, and various sensors used to interact with the computer.
    • Output devices include the monitor, speakers, and printers for displaying and producing information.
  8. Optical Drives:
    • Optical drives, such as DVD and Blu-ray drives, are used to read and write optical discs for data storage and media playback.
  9. Expansion Cards:
    • Expansion cards can be added to the motherboard to provide additional features or functionality. Examples include sound cards, network cards, and video capture cards.
  10. Cooling System:
    • Computers generate heat during operation, so cooling systems, including fans and heat sinks, are crucial to dissipate heat and prevent overheating.
  11. Case (Chassis):
    • The computer case houses all the components and provides physical protection. It also includes connectors for I/O devices and cooling fans.
  12. Operating System (OS):
    • The operating system is software that manages hardware resources, provides a user interface, and allows users to run applications. Examples include Windows, macOS, and Linux.
