Basic Parts of Computer System

Comp6670.047
Identify the basic parts of a computer system and the relationships among components.

Hardware-The physical components of a computer, including processor and memory chips, input/ output devices, tapes, disks, modems, and cables.

Software-a set of instructions or code to be executed by the CPU; designed to help users solve problems or perform tasks.

Users-the person who inputs and analyzes data using a computer.

Data-raw facts, numbers, letters, or symbols that the computer processes into meaningful information.

These work together by the software that is on the hardware and the user uses the hardware on the software to obtain data.

If we were missing any of these parts or just one such as the user the the hardware would be useless because there would be no one to use the hardware.
