Match the file organization method with its correct description: Sequential File Organization Direct/Random File Organization Direct File Access Method Index Sequential Access Method
Understand the Problem
The question asks to match file organization methods (Sequential, Direct/Random, Direct File Access, Index Sequential Access) with their correct descriptions. The goal is to correctly pair each method with how data is stored and accessed within the file system.
Answer
Matching descriptions include sequential access in order, direct/random access in any order, and index sequential access using an index for both sequential and direct access.
Here's a matching of file organization methods with their descriptions:
- Sequential File Organization: Records are stored and accessed in a specific order, one after the other, typically starting from the beginning of the file.
- Direct/Random File Organization: Records can be accessed in any order, allowing immediate access to specific records based on their address or key.
- Index Sequential Access Method: Uses an index to enable both sequential and direct access to records. The index provides a quick way to locate records for direct access, while sequential access is still possible.

More Information
File organization is a crucial aspect of data management, influencing access speed and efficiency.
Tips
A common mistake is confusing direct access with sequential access. Direct access allows you to jump to any record, while sequential requires you to go through the records in order.
