A computer system is a collection of interconnected hardware and software components that work together to perform specific tasks. The hardware encompasses all the physical parts of the computer, such as the central processing unit (CPU), which acts as the brain, memory (RAM) for temporary data storage, storage devices like hard drives or SSDs for long-term data retention, input devices like keyboards and mice, and output devices such as monitors and printers.

The software, on the other hand, comprises the instructions and programs that tell the hardware what to do. This includes the operating system, which manages the system's resources and provides a user interface, and application software, which performs specific functions like word processing, web browsing, or gaming. Together, hardware and software enable a computer system to process data, execute commands, and produce results.

Computer systems vary widely in complexity and purpose, from the smallest embedded systems found in appliances to the most powerful supercomputers used for scientific research. They are fundamental to modern society, underpinning communication, information access, automation, and countless other activities. The continuous evolution of both hardware and software drives the ongoing advancements in computing capabilities and their applications.
