These functions are also known as the input function, process function, output function, and storage function, respectively. Taking data and instructions from a user, processing the data as per instructions, and displaying or storing the processed data, are the four major functions of a computer. These functional units are called as stages of the pipeline. These are These units are as follows: Input unit Central Processing unit Output unit These units are interconnected by electrical cables to permit communication between them. Digital computer systems consist of three distinct units. Central Processing unit further includes Arithmetic logic unit and control unit, as shown in the figure:. 1. The input devices translate the information into a form understandable by the computer. The functional hierarchy diagrams present the levels of functional breakdown of functional requirements to components and units. Each functional unit performs a dedicated task. It is Central Processing Unit of the computer. The following five units (also called “The functional units ”) correspond to the five basic operations performed by all computer systems. Event driven programming. The input unit consists of one or more input devices. The architectural design of a computer system is concerned with the specifications of the various functional modules, such as processors and memories, and structuring them together into a computer system. Computers then use their CPU to process this data and produce output. A computer architecture deals with the specification of an instruction set and the hardware units that implement the instructions. A functional flow block diagram (FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system’s functional flow. Functional Units 2. For example, a … Cross-Functional Flowcharts . Block Diagram of Computer. These units are interconnected by electrical cables to permit communication between them. This allows the computer to function as a system.
