Final answer:
A numerical filing system requires a master list of clients and assigns each client a unique number for efficient filing and retrieval, commonly used in settings with large records like medical or legal offices.
Step-by-step explanation:
A type of filing system that requires a master list of clients is the numerical system. In such a system, each client is assigned a unique number, which is then used to file and retrieve client information efficiently. This method allows for an organized structure, where the master list serves as the key to locating each client's folder or records quickly. This system is particularly useful for maintaining large numbers of records, such as in a medical or legal office setting, where memorizing client names is impractical. The numerical system also enhances privacy and confidentiality as it doesn't expose client names directly on the folders or in external indexing systems.
A subject-oriented filing system requires a master list of clients. In this type of system, files are grouped together based on a specific subject or topic. For example, a company may have separate files for each client, with all documents relating to that client stored together.
This system allows for easy organization and retrieval of information. If a company needs to find a document related to a specific client, they can simply refer to the master list and locate the appropriate file. This system is commonly used in businesses and other organizations to maintain organized records.
