The main components of a computer system are hardware, software, and data.

Hardware refers to the physical components of the computer, such as the CPU, memory, storage, and input/output devices. These tangible items make up the foundational structure necessary for a computer to operate.

Software comprises the applications and system software that instruct the hardware on how to perform specific tasks. This includes the operating system, utility programs, and application software that allow users to perform functions from simple tasks to complex operations.

Data is the information that the computer processes and manages. It can be in various forms—be it documents, images, or databases—and it is essential for software to function correctly, as programs manipulate this data to perform tasks.

Overall, hardware provides the infrastructure, software delivers the instructions, and data represents the information processed by the system, creating a comprehensive understanding of how a computer system operates.
