If we will going to explore the computer based information system so we will come to know that the whole idea is depend upon the six basic elements and all these six element are interconnected with each other which means if anyone of the element is missing then there is no concept of Computer-based information will remain.Lets have a look towards its six basic elements in which include:-

Hardware
Software
Data/Information
People
Procedures
Communication

Lets Go through the detailed structure of all above elements so

The term computer describers a device which is made up of a combination of electronic and electromechanical ( part of electronic; and part of mechanical).Bt itself a computer is nothing or we can say that it has no intelligence and it is referred to as Hardware, which means simply the physical equipments. The hardware cannot be used until it is connected to other elements all of which constitute the 6 parts of a computer based information system

Software:- If talking about the Software part then it is the term which is used to describe the instructions that tell the hardware how to perform a task. Without software there is no concept of utilizing a hardware and there is no use of any hardware.

Data / Information:- The Primary purpose of Computer systems in most businesses today is to transform data into information that be used by people to make their decisions, to sell their products and perform a varieties of other activities . So it is so important that we must know what is Data and what is information .Actually a data can be considered the raw material – whether in paper, in electronic or in any other form that is processed by the Computer. In simple words a data consist of the raw facts and figures that are processed into information. On other end if we talk about information so the Information is summarized data or otherwise manipulated processed data. for instance, the raw data of employs hours worked and wage rates is processed by a computer into the information of paychecks and payrolls.But keep in mind that information s not same as the knowledge Information is a data that has been organized and communicated, but a knowledge requires the application of reason.

People:- By the name it is clear that an individual who operates the Computer system, create and use the software applications, as well as people will face the ethical issues and decisions regarding the use of information technology. In short peoples are the most important component of Computer system.

Procedures:- These are the descriptions of how things are done, and these are the steps for accomplishing a result. Procedures for computer systems appear in documentation manuals and it is also known as reference manuals and user guides which contain instructions, rules and guidance to follow when using hardware and software.

Communications:- It is also called connectivity, when one computer system is set up to share data and information electronically with another computer then a communication take place. In other words the manner in which the various individual systems are connected , for example by phone lines,or satellite
