The records of students in a school are kept in order of their arrival. What files access method would be used to access a student's record if the latest record would first be retrieved?

Answer Details
If the records of students are kept in order of their arrival and the latest record would be retrieved first, then the appropriate file access method would be "sequential." Sequential file access involves accessing records in a particular order, such as the order in which they were added to the file. In this case, the records of students are kept in order of their arrival, so a sequential file access method would be used to access their records. When a sequential file is accessed, each record is read one after another until the desired record is found. In this case, the latest record would be the last record in the file, so the program would read through all the previous records until it reaches the end of the file and finds the latest record. Direct file access involves accessing records based on their physical location on the storage medium, while indexed file access involves using a separate index file to locate records. Batch file processing involves processing multiple jobs or tasks at once, rather than one at a time. In summary, if the records of students are kept in order of their arrival and the latest record would be retrieved first, the appropriate file access method would be "sequential."
