Program Flow Chart and System Flow Chart (11/12)

Program flowchart and system flowchart

Programs are the collection of set of instruction which perform some certain activities. These interrelated programs are collectively called software or in general we call it information system. Information system is capable of processing raw data into information depending upon the users requirements. Thus, information system should process several types of data for several purpose or job which are done through programs. In short information system is a collection of programs.
While developing a software, we design our software by using flowchart and other several designing tools. Flowchart is the diagrammatic or pictorial representation of steps involved while solving a problem. It illustrates the sequence of operations required to solve a problem. There are mainly two types of flowchart: Program flowchart and System flowchart.

Program flowchart: It represents the steps involved in solving a particular problem. It illustrates the flow of logic and sequence of a program in which it is executed. It is a detailed diagram showing how a program process input data into desired output. Several symbols can be used while designing a program flowchart.

System Flowchart

As system consists of several integrated programs it’s almost impractical to illustrates whole system control flow through a diagram so, we will system flowchart to illustrate broad over view of a overall system. It is use to represent the structure of the system and its elements with relationship. Several symbols can be used while designing a system flowchart.

Different between Program flowchart and System flowchart

Program flowchart

System flowchart

It illustrates the control flow of a specific program.

It illustrates the broad overview of overall system.

It is used to solve specific problem.

It is used to process data.

It shows flow of instruction in a program

It shows data flow in a system.

Its operations are limited and has less symbols.

Different kinds of symbols with several functionality can be used .

It is designed by programmer.

It is designed by system designer.

Program flowchart are designed during development once whole system design is finalized.

System flowchart should be designed in advanced before proceeding to development 

It has no further category.

It has many category such as E-R diagram, Data Flow Diagram, Context diagram etc.

Eg, Program to sort in ascending, Program to find greatest number among N numbers etc

Eg, Library Management System, Marksheet Evaluation System, Payroll System, Inventory Management System.

  Basic elements of Communication System Information Source: The term "information source" refers to the origin or starting point of information that needs to be conveyed to a recipient or receiver. It represents the entity or process that generates the data or messages to be communicated. The information source is a fundamental concept in communication theory and plays a crucial role in the overall communication process. Input Transducer: An input transducer, often simply referred to as a transducer, is a device or component that converts one form of energy or physical quantity into another. In the context of electronics and instrumentation, input transducers are used to convert physical phenomena, such as temperature, pressure, light, or sound, into electrical signals that can be measured, processed, or transmitted by electronic systems. Transmitter: A transmitter is a key component responsible for transmitting information or data from the source to the communic
