Explain how many records can be stored per track, Operation Management

Assignment Help:

1. Given: a block addressable disk drive with 4,200 bytes per track and overhead 50 bytes per block. A le contains 50 byte records. How many records can be stored per track if the blocking factor is 20? Please show all your work!

2. Consider a le with 3200 records occupying two hundred data pages (i.e., B=200 and R=16). The average time to read or write a disk page is 15 microseconds (I.e., D=15 microseconds), and the average time to process a record is 0.1 microseconds (i.e., C=0.1 microseconds). The time required to apply the hash function is 0.5 microseconds (i.e., h=0.5 microseconds). Assume (1) only scan and equality search operations are used, and (2) on average, the scan operation is used in 10% of the cases and the remaining cases use equality searches. Which le organization (heap, sorted, or hashed) would you select and why?
