Software- System software, operating system, network software (if necessary) and also the application programs Data : - Used by the organization and a description of this data called the schema. Procedures : - Instructions and rules that should be applied to the design and use of the information system. People - Who uses the software in order to do their job.
[DBU] [College of Computing Science]  Compiled By: S. E. 6/11 SAD – Chap1 Figure 1.3: Components of IS Application Complete diagram Of Components of Information System The below diagram illustrates on information system model that express a fundamental conceptual frame work for the major components and activities of information systems. Figure 1.4: Basic Components of Information System As we know an information system uses the resources of people (end users and IS specialists), hardware (machines and media), software (programs and procedures), data (data and knowledge base and networks (communications media and network support) to perform input, processing, output, storage, and control activities that covert data resources into information products. Our basic IS model show that on information system consists of five major resources. People, hardware, software, data and networks. Uses should be able to recognize these five components at work in any type of information system you on counter in the real world. People are required for the operation of all information systems. These people resources include End users and are specialists. A. End Users and IS Specialists
[DBU] [College of Computing Science]  Compiled By: S. E. 7/11 SAD – Chap1 End Users (also called users or clients) are people who use on information system or the information it produces. They can be accounts, sales persons, engineers, clerks, customers, or managers. Most of us are information system end users. IS specialists are people who develop and operate information systems. They include systems analysts, programmers, computer operators and other managerial, technical, and clerical IS personnel. Briefly, System analysis design information systems based on the information requirement of end users; programmers prepare computer programs based on the specifications of systems analysts; and computer operators operate large computer systems. The concept of hardware resources includes all physical devices and materials used in information processing. Specifically it includes not only machines, such as computer and other equipment but also all data media that is all tangible objects C. Software Resources The concept of software resources includes all sets of information processing instructions. This generic concept called programs, which direct and control computer hardware, but also the sets of information processing instruction needed by people, called procedures. Example of software resources System software such as an operating system program, which controls and supports the operation of a computer system. Application software , which are, programs that direct processing for a particular use of computers by end users. Examples are a sales analysis program, a pay roll program, and a word processing program.
