A computer system is a collection of hardware, software, and peripheral devices that work together to process data and perform tasks. The hardware components include the central processing unit (CPU), memory (RAM), storage devices (such as hard drives or solid-state drives), input devices (such as keyboards or mice), output devices (such as monitors or printers), and other components that facilitate communication and data transfer within the system. The software components include the operating system, applications, and other programs that allow users to interact with the system and perform tasks. Together, these components enable computers to perform a wide range of functions, from basic arithmetic operations to complex calculations and data processing tasks.
