A block diagram is an essential method used to develop and describe software or hardware systems while illustrating their processes and workflows. As shown in the computer block diagram, this method is used to represent systems and their shiftings. For representing any system using a block diagram, it is necessary to find the transfer function of the system. A computer block diagram usually has ROM or RAM, a control unit, and an arithmetic & logic unit that takes the data or information from the input device like keyboard or mouse. The computer block diagram shows how the CPU performs the logic and prints the result on the output devices like an LCD screen or a printer. Instead of creating a computer block diagram from scratch, use EdrawMax pre-defined templates as it provides the right facts and figures that ease the entire process.
