Question 3

Assume you have a file of 10 records (identified as A, B, C, . . . J) to be stored on a disk that holds 10 records per track. Once the file is stored, the records will be accessed sequentially: A, B, C, . . . J. It takes 1 ms to transfer each record from the disk to main memory. It takes 2 ms to process each record once it has been transferred into memory and the next record is not accessed until the current one has been processed. It takes 10 ms for the disk to complete one rotation.

Suppose you store the records in the order given: A, B, C, . . . J. Compute how long it will take to process all 10 records. Break up your computation into (1) the time to transfer a record, (2) the time to process a record, and (3) the time to access the next record.
