A computer based information system is needed : I. as it is difficult for administrative staff to process data. II. due to rapid growth of information and communication technology. III. due to growing size of organizations which need to process large volume of data. IV. as timely and accurate decisions are to be taken. Which of the above statement(s) is/are true ?
III and IV
An organisation needs a computer based information system (CBIS) when its own information requirements can no longer be met manually — the need comes from the organisation, not from the technology.
Statement III is true: as organisations grow, the volume of transactions and data becomes too large to capture, store and process by hand quickly and without error.
Statement IV is true: managers must take timely and accurate decisions, which needs up-to-date, accurate, summarised information that a CBIS supplies.
Statement I is false: administrative staff can process data — manual systems worked for small volumes; the difficulty arises only from volume and speed, which is already statement III. Statement II is false as a reason: growth of ICT makes a CBIS possible and cheaper, but technology growth by itself does not create the organisation's need.
So the true statements are III and IV.
Hence, the answer is III and IV.
