Question

Which of the following is not a limitation of file systems?

• A. Data Redundancy
• B. Data Inconsistency
• C. Data dependence
• D. Storing Space

Answer 1

The Correct Option is D

In the context of computer science, particularly relating to file systems, understanding the limitations is crucial for effectively managing and organizing data. Below is an explanation of each option provided, highlighting the one which does not act as a limitation. 

• Data Redundancy: File systems often suffer from data redundancy, meaning the same data is stored in multiple locations, leading to storage inefficiencies and increased chances for data inconsistency.
• Data Inconsistency: When data is redundant, especially in file systems, there is a high likelihood of data inconsistency occurring. This happens when changes made in one file are not propagated to all copies of the data, resulting in conflicting information being stored.
• Data Dependence: Traditional file systems are characterized by data dependence, which refers to the tight coupling between data and applications. This makes it difficult to change the data format or structure without modifying the application code.
• Storing Space: Storing space itself is not inherently a limitation of file systems. Rather, issues arise when inefficient storage due to the other limitations listed here come into play. Therefore, storing space as an isolated concept is not a limitation caused by file systems.

Given these explanations, the correct answer to the question is: Storing Space. Unlike the other options, storing space is not a direct limitation of file systems.

Answer 2

(1) Data Redundancy: File systems often lead to data redundancy because the same data might be stored in multiple files or locations. This is a common limitation.

(2) Data Inconsistency: Because of data redundancy, it's difficult to ensure that all copies of the same data are consistent. If one copy is updated, others might not be, leading to inconsistency. This is a typical problem in file systems.

(3) Data dependence: In file systems, the data structure is often tightly coupled with the applications that use it. Changes to the data structure can require modifications to the applications, leading to data dependence.

(4) Storing Space: File systems manage and allocate storage space. While they do have limitations related to how they organize and utilize storage, the act of storing space is not a limitation. Storing data requires storage space. This is fundamental to any data storage system. Rather, a limitation could be inefficient use of storage space or limited scalability of storage.

Therefore, the option that is not a limitation of file systems is (4) Storing Space.
