What is System concept definition and characteristics of system?

This question is in my syllabus of BCA TY, if anyone can briefly explain me the answer would be great

System Concept

  • A system is an organized collection of highly integrated parts or subparts to complete a specific purpose target.
  • The system has several inputs which go under certain procedures to generate particular outputs, all of which fulfill the specified objective of the system.

Three basic concepts of the system:

  • The system was created or designed in a such way that to complete specific predetermined objectives.
  • Parts and subparts of the system must have interdependence and interrelationships among them.
  • The goals of the organization always have high priority rather than the goals of the subsystem.

Characteristics for a System

There are five types of characteristics for a system. Such as,

1. Organization

2. Interaction

3. Interdependence

4. Integration

5. A central objective


  • This implies structure and order.
  • It can also be defined as the arrangement of components that help to achieve objectives.
  • For example, Hierarchical system in a company.


  • This shows the manner in which each component functions with other components of the system.
  • It specifies there should be an interrelationship between every component of a system.
  • For example, the main memory holds the data that has to be operated by the ALU.


  • This means the components of a computer system depend on one another.
  • Each component should depend on other components of the system.
  • One component depends on the input of another component for proper functioning.
  • The output of one subsystem is the required input for another subsystem.
  • For example, A decision to computerize an application is initiated by the user, analyzed and designed by the analyst, programmed and tested by the computer operator. None of the persons can perform properly without the required input from others in the computer center subsystem.


  • It is concerned with how a system is tied together.
  • It is more than sharing physical components or locations.
  • It means that components of the system work together within the system even though each component performs a unique function.


  • Systems always have a central goal.
  • These goals may be real or stated.
  • The important point is that users must know the central objective of a computer application early in the analysis for a successful design and conversion.
