Explain block diagram of computer

A block diagram of a computer shows a computer's functional components and their interconnections. The four major components of a computer are the input devices (keyboard, mouse), the CPU, which performs instructions, the memory units (RAM, ROM), which store data, and the output devices (monitor, printer).

Input data flows to the CPU, where it is processed and memorized. The CPU reads information and commands from memory, analyses them, and then transmits the finished product to output devices. The computer can efficiently run programs and carry out a wide range of activities because of this sequential flow, giving it an extensible tool for communication, computation, and information processing.
