Components of a Personal Computer

Computers are made up of several important components that work together to perform tasks efficiently. The Central Processing Unit (CPU) acts as the brain of the computer, processing instructions and calculations. The Random Access Memory (RAM) stores temporary data that programs need while running, helping the system operate quickly.

The storage device, such as a Solid State Drive (SSD) or Hard Disk Drive (HDD), stores the operating system, applications, and user files. The motherboard connects all hardware components and allows them to communicate with each other. A power supply unit (PSU) provides electrical power to the system, while the graphics processing unit (GPU) handles graphics and visual output.

Together, these components enable a computer to perform a wide range of tasks, from web browsing and document editing to gaming and professional applications.
