What Is Block Diagram Of Computer System

Input unit central processing unit and output unit.

What is block diagram of computer system. In the diagram below the control unit cu and the arithmetic logic unit alu make up the central processing unit cpu in a computer. So a computer is normally considered to be a calculating device that performs arithmetic operations at enormous speed. The computer system consists of mainly three types that are central processing unit cpu input devices and output devices the central processing unit cpu again consists of alu arithmetic logic unit and control unit. Block diagram what is a block diagram.

A block diagram is a specialized high level flowchart used in engineering. Its structure provides a high level overview of major system components key process participants and important working relationships. Block diagram of computer system. A computer system mainly has three components viz.

It is the brain cum the heart. This is the process of entering data and programs in to the computer system. It displays the necessary processes needed to get the desired output from a computer from the input you feed into at the start. The basic elements of a block diagram are a block the summing point and the take off point.

Computer the word computer comes from the word compute which means to calculate. Block diagram of computer. Block diagram of a computer gives you the pictorial representation of a computer that how it works inside. When we get inside working of computer we find that there are different hardware components categorized under different types or unit playing their roles to support the overall processing of a computer system.

The relationship among these components is well established by the following diagram. Let us consider the block diagram of a closed loop control system as shown in the following figure to identify these elements. Here is the block diagram of a computer system. Block diagram of computer and explain its various components.

The set of instruction is presented to the computer in the form of raw data which is entered through input devices such as keyboard or mouse. A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They can solve highly complicated problems quickly and accurately. Basic elements of block diagram.

A computer takes help of a different device to perform a different job. A computer can process data pictures sound and graphics. A computer can process a large volume of data and produce a desirable result. It is used to design new systems or to describe and improve existing ones.

Block diagrams are typically used for higher level less detailed descriptions that are intended to. The above block diagram consists of two blocks having transfer functions g s and h s. Block diagram of computer and its various components. They are heavily used in engineering in hardware design electronic design software design and process flow diagrams.
