What are components of computer based information system?
category includes the computer itself, which is often referred to as the central processing unit (CPU), and all of its support equipment’s. Among the support equipment’s are input and output devices, storage devices and communications devices.
Types of Computer Based Information Systems Show 1. Transaction Processing SystemsThe most fundamental computer based system in an organisation pertains to the processing of business transactions. A transaction processing system can be defined as a computer based system that captures, classifies, stores, maintains, updates and retrieves transaction data for record keeping and for input to other types of CBIS. Transaction Processing Systems are aimed at improving the routine business activities on which all organizations depend. A transaction is any event or activity that affects the whole organisation. Placing orders, billing customers, hiring of employees and depositing cheques are some of the common transactions. The types of transactions that occur vary from organisation to organisation. But this is true that all organisations process transactions as a major part of their daily business activities. The most successful organisations perform this work of transaction processing in a very systematic way. Transaction processing systems provide speed and accuracy and can be programmed to follow routines without any variance. 2. Management Information SystemData processing by computers has been extremely effective because of several reasons. The main reason being that huge amount of data relating to accounts and other transactions can be processed very quickly. Earlier most of the computer applications were concerned with record keeping and the automation of routine clerical processes. However, in recent years, increasing attention has been focused on computer applications providing information for policy making, management planning and control purposes. Management Information System are more concerned with management function. MIS can be described as information system that can provide all levels of management with information essential to the running of smooth business. This information must be as relevant, timely, accurate, complete and concise and economically feasible 3. Decision Support SystemsIt is an information system that offers the kind of information that may not be predictable, the kind that business professionals may need only once. These systems do not produce regularly scheduled management reports. Instead, they are designed to respond to a wide range of requests. It is true that all the decisions in an organisation are not of a recurring nature. Decision support systems assist managers who must make decisions that are not highly structured, often called unstructured or semi-structured decisions. A decision is considered unstructured if there are no clear procedures for making the decision and if not all the factors to be considered in the decision can be readily identified in advance. Judgement of the manager plays a vital role in decision making where the problem is not structured. The decision support system supports, but does not replace, judgement of manager. 4. Office Automation SystemsOffice automation systems are among the newest and most rapidly expanding computer based information systems. They are being developed with the hopes and expectations that they will increase the efficiency and productivity of office workers-typists, secretaries, administrative assistants, staff professionals, managers and the like. Many organisations have taken the First step toward automating their offices. Often this step involves the use of word processing equipment to facilitate the typing, storing, revising and printing of textual materials. Another development is a computer based communications system such as electronic mail which allows people to communicate in an electronic mode through computer terminals. An office automation system can be described as a multi-function, integrated computer based system that allows many office activities to be performed in an electronic mode. Categories of different information systems with their characteristics have been described briefly in table below. Category of Information SystemCharacteristicsTransaction Processing SystemSubstitutes computer-based processing for manual processes. Includes record-keeping applications.Management Information SystemProvides input to be used in the managerial decision process. Deals with supporting well structured decision situations. Typical information requirements can be anticipatedDecision Support SystemProvides information to managers who make judgements about particular situations. Supports decision makes in situations that are not well structured.Office Automation SystemIt is a multi-function, integrated computer based system, that allows many office activities to be performed in an electronic mode.

Computer Software: The programs/ application program used to control and coordinate the hardware components. ... . Databases: ... . Network: ... . Human Resources:. How many component A CBIS has?The CBIS model has eight components that should be in place for a system that produces high-quality information for decision making. The components are leadership and governance; system design; system management; data sources; data management; information products and dissemination; data quality; and data use.
What are the components and applications of computerThe elements of computer-based systems are defined as software, hardware, people, database, documentation, and procedures. A computer-based system makes use of a variety of system elements. Software: programs, data structures, and related work products. Hardware: electronic devices that provide computing capabilities.
