DATA PROCESSING INFORMATION, The term system is the most loosely held term in management literature because of its.
use in different contexts However a system may be defined as a set of elements which are. joined together to achieve a common objective The elements are interrelated and. interdependent, The set of elements for a system may be understood us input process and output A. system has one are multiple inputs these inputs are processed through a transformation. process to convert these input into outputs The three elements of a system are. INPUT PROCESS OUTPUT, 2 What are the various functions of information systems. One of the mostly widely used bases for organising activities in almost every. organisation is the business function Business activities are grouped around functions. such as production marketing finance and personnel etc Resulting in the respective. department or an area of the business organisation These departments or functional areas. are commonly known as the functional areas of business. There is no standard classification of such sub system in an organisation but a. typical set of functions in a manufacturing organisation includes. Production,Finance and accounting,Materials and,Personnel systems. Production,Production planning and control,Engineering standards. Quality control,Sales order,Forecasting,Sales analysis.
Distribution,Stock availability,Sales quota control. Product promotion,Finance and accounting,Financial planning. Cost accounting,Asset accounting,Accounts receivable. Accounts payable etc,Material planning,Bill of material. Cost estimate,Warehousing planning etc,Employee recruitment.
Employee selection,Employee development,Employee transfers. Employee retirements etc,3 Discuss about information system resources. In information system includes four major resources hardware software people. and data Let s briefly discuss some basic concepts and examples of how these resources. contributes to the information processing activities of information system. Hardware it includes all physical devices, Software it includes all set of information processing. instructions, People people are required for the operation of all. information systems These people resources include specialists. and end users, Data data is more than the raw material of information.
systems The concepts of data resources have been broadened by. managers and information system professionals,4 List out the different types of information. Information could be classified on the basis of the purpose for which it is. utilised into three main categories, Strategic information it is required by the managers at the strategic level. of management for the formulation of organisational strategies.

system which is a special kind of DSS An ESS is specially tailored for the use of chief. executive of an organisation to support his decision making. An ESS is designed to cater to the information needs of a chief executive keeping. in view not only his requirements but also taking into account his personality and style of. functioning etc,Office automation system, Office automation refers to the application of computer and communication. technology to office functions Office automation systems are meant to improve the. productivity of managers at various level of management by providing secretarial assistance. and better communication facilities Office automation systems are the combination of. hardware software and people in information systems that process office transactions and. support office activities at all levels of the organisation. These systems include a wide range of support facilities which include word. processing electronic filing electronic mail message switching data storage data and voice. communication etc, In the first category the following is a list of activities. Scheduling of meetings and conferences,Calendar keeping and. Retrieving documents,In the secondary category,Conferencing. Production of information,Controlling performance,Business expert system.
Business expert system BES is a knowledge based information system that uses its. knowledge about a specific complex application area to act as an expert This system is. one of the knowledge based information system, Expert system provides decision support to managers in the form of advice from an. expert in a specific problem area Expert systems find application in diverse areas. ranging from medical engineering and business,Knowledge base inference engine. user interface,2 Discuss about cost benefit analysis. Every legitimate solution will have some advantages is benefits and some. disadvantages or costs These advantages and disadvantages are identified when each. alternative solution is evaluated This process is typically called cost benefit analysis. Examples in sales or profits,in operating costs,in required investment. Selecting the best solution, Once all alternative solutions have been evaluated the process of selections the best.
solution can begin Alternative solutions can be compared to each other because they have. been evaluated using the same criteria It is possible that to decide to select the best solution. to the problem,Implementing a solution, Once a solution has been selected it must be implemented An implementation plan. may be developed An implementation plan specifies the activities resources and timing. needed for proper implementation,Post implementation review. The final step of the system approach recognized that an implemented solution can. fail to solve the problem for which it was developed The results of implementing a solution. should be monitored and evaluated This is called a post implementation review process. Global business strategies, MNC is a firm that operates across products markets nations and cultures It consists. of the parent company and a group of subsidiaries They are geographically disresed and each. one may have its own unique goals policies and procedures.

Computer system which consists of central processing units. containing microprocessors and a variety of interconnected. peripheral devices Example handheld laptop midrange computer. systems and large mainframe computer systems, Computer peripherals which are devices such as a keyboard or. electronic mouse for input of data and commands a video screen or. printer for output of information and magnetic or optical disks for. storage of data resources,Software resources, It includes all set of information processing instructions It includes not. only the set of operating instructions called programs Examples are. System software such as an operating system program which. controls and supports the operations of computer system. Application software which are programs that direct processing for. a particular use of computers by end users Example sales analysis. program a payroll program and a word processing system. Data resources, Data resources of information systems are typically organised stored and. accessed by a variety of data resources mgt technologies into. Database that hold processed and organised data, Knowledge bases the hold knowledge in variety of forms such as facts. rules and case,Network resources, Telecommunications technologies and networks like the internet intranets and.
extranets The concept of network resources emphasizes that communications technologies. and networks are a fundamentals resource component of all information systems Network. resources include, Communications media is includes twisted pairs wire coaxial and fiber. optic cables and microwave cellular and satellite wireless technologies. Network infrastructure this generic category emphasizes that many. hardware software and data technologies are needed to support the. operation and use of a communication networks, 4 Write about the fundamentals and dimensions of information system.
