Main Devices

The main devices in building a computer rely on a cohesive architecture where each hardware component works in interaction with the others and with the operating system to deliver the desired performance, stability, and potential. Optimization is achieved in how they integrate to form a functional ecosystem. The quality of a component directly influences the functionality of the whole, and the interaction between hardware and software is what defines the final user experience.

To make a computer a functional and interactive system, a robust interface between the user and the system is essential. This is precisely the role of input and output devices, which allow information to flow in both ways.
