File Handling

• What is a file?

  A collection of data stored on a computer's storage device.
• What is buffering in file handling?

  The process of temporarily storing data in a buffer before writing it to a file.
• What is read mode in file handling?

  Open a file for reading.
• What is buffering used for in file handling?

  To improve the performance of file input/output operations by reducing disk I/O and improving data integrity.
• What is one benefit of buffering in file handling?

  To improve the performance of file input/output operations by reducing disk I/O operations.
• How does buffering reduce disk I/O operations?

  By grouping data into larger chunks, reducing the number of disk seeks and improving system performance.
• What role does buffering play in serialization?

  Buffering plays a crucial role in serialization by grouping serialized data into larger chunks, reducing the number of disk seeks, and caching data in memory.
• Why is grouping data important in buffering?

  To reduce the number of disk seeks, improve data transfer, enhance data compression, and simplify data handling.
• How does grouping data improve compression?

  By allowing for pattern recognition, improving predictability, reducing overhead, increasing locality, and providing better context for compression algorithms.
