Answers.


The conclusion of the CBISA computer-based information system (CBIS) is an information system in which the computer plays a major role. Such a system consists of the following elements:
 • Hardware: The term hardware refers to machinery. This category includes the computer itself, which is often referred to as the central processing unit(CPU), and all of its support equipments. Among the support equipments are input and output devices, Storage devices and communications devices.


 • Software: The term software refers to computer programs
and the manuals (if any) that support them. Computer programs are machine-readable instructions that direct the circuitry within the hardware parts of the CBIS to function in ways that produce useful information from data. Programs are generally stored on some input / output medium-often a disk or tape.


 • Data: Data are facts that are used by program to produce useful information. Like programs, data are generally stored in machine-readable from on disk or tape until the computer needs them. 


• Procedures: Procedures are the policies that govern the operation of a computer system. "Procedures are to people what software is to hardware" is a common analogy that is used to illustrate the role of procedures in a CBIS.


 • People: Every CBIS needs people if it is to be useful. Often the most over-looked element of the CBIS is the people: Probably the components that most influence the success or failure of information system
