No worries! Glad it helped!
Also, the answers to your questions:
a) Cyclic redundancy check (CRC) is a method used to detect errors in transmission – a method 99.99% more effective than check sum. Hence, in this information system, it could be used when the details of the customer when they are applying for a loyalty card are transmitted to the department store.
Note: I don’t think I wrote an adequate amount…and if I did this correctly….
c) In this information system:
- Internet would be used to access the online department store for shopping and applying for a loyalty card. It would also be used when the customers receive advertising emails from the business partners of the online department store.
- Intranet would be used when the store shares information with its employees.
- Extranet would be used for when the store shares information with its business partners.
Note: Not too sure about this question either…… :’(
