Computer systems consist of several core components that enable them to function and perform tasks. These components include:
- Hardware: The physical parts of a computer such as the CPU, memory units, and I/O devices.
- Software: Programs and operating systems that run on hardware, directing its operations.
- Input Devices: Tools used to input data into a computer (e.g., keyboard, mouse).
- Output Devices: Devices that output data from a computer (e.g., monitors, printers).
- CPU (Central Processing Unit): Acts as the brain of the computer, processing instructions.
