Final answer:
Information is stored in computer-based information systems through digital storage devices, memory systems, and concepts.
Step-by-step explanation:
Information is stored in computer-based information systems in a variety of ways. One common method is through digital storage devices, such as CDs and DVDs, which use lasers to create pits that represent digital information. These pits are read by a laser beam, allowing the encoded information to be retrieved. Another method is through the use of memory systems, similar to how our brains encode, store, and retrieve information. These computer memory systems can involve encoding the information, storing it electronically, and retrieving it as needed.
Additionally, concepts are used to organize and store information in computer-based information systems. Concepts are like files in a file cabinet, where different categories or groupings of information are stored. Concepts allow for the organization and accessibility of information in an organized manner. Overall, information in computer-based information systems can be stored digitally on storage devices, in memory systems, and through the use of concepts.
