A computer system relies on key hardware components that determine its performance.

Main Components:

• CPU (Central Processing Unit) – Handles instructions and calculations
• Backing Storage – Keeps data long-term
• Main Memory (RAM) – Holds data temporarily for running programs

Knowing these parts helps when choosing or upgrading a computer.

• A faster CPU means quicker processing

• More RAM allows for smoother multitasking

• Better storage means faster access and more space for files

Understanding how these components work together helps make smart choices when buying or upgrading a system.
