Computer hardware refers to the physical components that make up a computer system. These components include the central processing unit (CPU), random-access memory (RAM), hard disk drive (HDD), graphics processing unit (GPU), motherboard, power supply, and peripherals such as monitors, keyboards, and mice.
The CPU, often referred to as the brain of the computer, performs most of the calculations and controls the system's operation. RAM is responsible for temporarily storing data that the CPU needs to access quickly. The HDD is used for long-term storage of files and programs. The GPU is dedicated to rendering and processing graphics, making it essential for tasks such as gaming and video editing.
The motherboard acts as the main circuit board connecting all the components together. It provides power, allows data transfer, and facilitates communication between different parts of the system. The power supply ensures that the computer receives a steady supply of electricity. Without it, the system would not be able to function.
Peripherals are external devices that are connected to the computer, enhancing its functionality. Monitors display visual output, while keyboards and mice are used for input. Other peripherals can include printers, scanners, speakers, and webcams.
In summary, computer hardware includes the CPU, RAM, HDD, GPU, motherboard, power supply, and peripherals. Together, these components work together to form a complete and functioning computer system.
