Information systems are in use from an ancient time. With the development of computing technology, computers became an important part of today's modern information systems which satisfies speed, dependability etc.
Following are the role of computers in Information Systems
1. Data Collection:Information systems collect, store and supply data. This is done by using computers. Data can be collected from computer networks or can be inserted by human resources. Software resources can also automate the collection of data (searching and finding best results) which is the most important part.
2. Data Verification:Data in information systems can be verified using computers. Thus data can be corrected or rejected before going to the processing level which final helps in getting accurate information.
3. Data Processing:Data in information systems can be processed (sorted, filtered, joined etc.) by computer to finally generate information that is desired, useful, meaningful to human resources or other information systems. Various program takes part in data processing.
4. Data Storing:Data is everything in information systems. Today's computers can store enormous amount of data. Information can derived from these stored at any time using data processing.
5. Supply of Information:
Computer can supply or provide information to human or another information system which can scheduled or manually operated.
