Finding a Specific Object in a Sequential Access File

Is finding a specific object in a sequential access file relatively easy?

True or False?

Answer:

True

Finding a specific object in a sequential access file is indeed relatively easy to do. The method used to find the object may depend on the size and organization of the file.

In a sequential access file, data is stored in a sequential manner, meaning that the records are stored one after the other in a specific order. This organization makes it easier to locate a specific object within the file.

One can start at the beginning of the file and read each record sequentially until the desired object is found. However, this method can be time-consuming for large files, especially if the object is located towards the end of the file.

Alternatively, if the file is sorted in a specific order, binary search can be utilized to swiftly find the desired object. Binary search involves dividing the file into two halves and determining which half the object is likely to be in based on its value. The search process continues in the appropriate half until the object is located.

Therefore, finding a specific object in a sequential access file is indeed relatively easy, but the efficiency of the method used may vary based on the size and organization of the file.
