1. 1.

   What is the purpose of file locking?

   Hint

   Think about situations where multiple applications use the same file.

2. 2.

   What function is used for random access in Python?

   Hint

   Remember, seek is about positioning within the file.

3. 3.

   What is the purpose of file locking?

   • Prevent data loss
   • Speed up access
   • Allow multiple accesses

   Hint

   Consider why you would want to limit file access.

4. 4.

   In Python, which method is used for random access to a file?

   Hint

   This method deals with positioning bytes.

5. 5.

   Create a Python program that uses file locking and allows writing to a file. Describe scenarios where this is beneficial.

   Hint

   Consider applications such as collaborative tools.

6. 6.

   Design a C++ function that demonstrates random access file reading using seekg(). Analyze how this improves data processing efficiency.

   Hint

   Focus on how this would benefit applications involving large datasets.
