Final answer:
In a computerized environment, the list of authorized suppliers is found in the master file, which includes long-term records that define entities such as suppliers. The master file is used over other file types like transaction, reference, and archive files due to its static and substantive nature.
Step-by-step explanation:
In a computerized environment, a list of authorized suppliers would typically be found in the master file. The master file is a compilation of records pertaining to the long-term information of an organization. These records are relatively static and are not subject to frequent changes. A master file contains data that defines entities such as suppliers, customers, employees, and products. This is versus a transaction file that stores temporary data about transactions that may change much more frequently.
When considering where to find a list of authorized suppliers, the following options may be on hand:
- A transaction file captures details about individual business transactions as they occur. It is regularly updated and the data often rolls into the master file after a certain period or after the transaction has been completed.
- A reference file is used mainly for look-up purposes and may store static data used by the system for validation or reference, but it’s not the primary source of substantive data like supplier lists.
- An archive file contains data that is no longer in active use and is stored for historical records or backups.
In conclusion, the correct answer is 1) master file.
