Architecture of Block diagram of Computer System

A computer's block diagram illustrates its main components and their interconnections. At its core is the central processing unit (CPU), which executes instructions and coordinates operations. Memory units, including RAM and ROM, store data and instructions temporarily and permanently, respectively. Input devices such as keyboards and mice feed data into the system, while output devices like monitors and printers display results. The CPU communicates with peripherals through buses, which transfer data and signals across the system. Power supplies provide electricity to all components. Together, these elements form the backbone of a computer, enabling it to process information and perform tasks efficiently.
