Practice

1. Why do file systems organize persistent storage on a computer?

easy

A. To delete files automatically

B. To slow down the computer

C. To keep data safe and easy to find

D. To make files invisible

Solution

1. Step 1: Understand the purpose of file systems

   File systems help manage how data is stored and retrieved on storage devices.

2. Step 2: Identify the main goal of organizing storage

   Organizing storage keeps data safe and makes it easy to find when needed.

3. Final Answer:

   To keep data safe and easy to find -> Option C

4. Quick Check:

   File systems organize storage to protect and locate data [OK]

Hint: File systems help find and protect data fast [OK]

Common Mistakes:

• Thinking file systems slow down computers
• Believing file systems delete files automatically
• Assuming file systems hide files from users

2. Which of the following is a correct way file systems organize data?

easy

A. Using folders and tables to track files

B. Randomly placing files without order

C. Storing all files in one big list

D. Deleting files after one day

Solution

1. Step 1: Recall how file systems track files

   File systems use folders (directories) and tables (like allocation tables) to organize files.

2. Step 2: Compare options to this method

   Only Using folders and tables to track files describes the correct method of organization.

3. Final Answer:

   Using folders and tables to track files -> Option A

4. Quick Check:

   Folders and tables organize files [OK]

Hint: Folders and tables help organize files clearly [OK]

Common Mistakes:

• Thinking files are stored randomly
• Believing all files are in one list
• Assuming files are deleted automatically

3. Consider a file system that uses a table to track file locations. What happens if the table is corrupted?

medium

A. Files may become lost or inaccessible

B. The computer runs faster

C. Files become easier to find

D. New files are automatically created

Solution

1. Step 1: Understand the role of the tracking table

   The table stores where each file is located on the storage device.

2. Step 2: Analyze the effect of corruption

   If the table is corrupted, the system cannot find files correctly, making them lost or inaccessible.

3. Final Answer:

   Files may become lost or inaccessible -> Option A

4. Quick Check:

   Corrupted table causes file loss [OK]

Hint: Corrupt table means files can't be found [OK]

Common Mistakes:

• Assuming corruption speeds up the computer
• Thinking files become easier to find
• Believing new files are created automatically

4. A user notices their files are not showing up after a system crash. Which file system issue is most likely the cause?

medium

A. Files were moved to a new folder

B. File allocation table is damaged

C. Computer ran out of memory

D. Files were deleted by the user

Solution

1. Step 1: Identify symptoms after a crash

   Files not showing up often means the system cannot locate them.

2. Step 2: Link symptoms to file system components

   A damaged file allocation table prevents the system from finding files, causing them to disappear from view.

3. Final Answer:

   File allocation table is damaged -> Option B

4. Quick Check:

   Damaged table hides files after crash [OK]

Hint: Missing files after crash? Check allocation table [OK]

Common Mistakes:

• Assuming user deleted files without proof
• Confusing memory with storage issues
• Thinking files moved automatically

5. A company wants to store millions of files efficiently and quickly retrieve them. Which file system feature best supports this goal?

hard

A. Saving files only in temporary memory

B. Storing all files in a single flat list without folders

C. Deleting files after 30 days automatically

D. Organizing files into hierarchical folders and using indexing tables

Solution

1. Step 1: Understand the need for efficient storage

   Millions of files require a system that can organize and locate files quickly.

2. Step 2: Identify file system features that help

   Hierarchical folders group files logically, and indexing tables speed up file lookup.

3. Final Answer:

   Organizing files into hierarchical folders and using indexing tables -> Option D

4. Quick Check:

   Folders plus indexing = efficient storage [OK]

Hint: Folders and indexes speed up large file storage [OK]

Common Mistakes:

• Thinking a flat list can handle millions efficiently
• Confusing temporary memory with persistent storage
• Assuming automatic deletion helps retrieval speed
