Which of the following type of file require longest processing time?
Correct answer: A. Sequential file
- A. Sequential file
- B. Random file
- C. Indexed sequential file
- D. Direct acess file
Explanation
Sequential files require longer processing times compared to other types of files because they are accessed in a linear fashion, from start to end. To find a specific record, the system must read through all preceding records sequentially, which can be time-consuming, especially for large files. Additionally, inserting or deleting records in a sequential file may require reorganizing the entire file, further increasing processing time.
