1. Assume each record in a database requires 2048 byes of information and there should be approximately 2 million records that need to be stored. Estimate the amount of storage needed in gigabytes for the database.

2. Assume the average memory access time for a computer is improved by a factor of 4 and a task spends 40% of the time accessing memory. Given that a task requires 12 seconds on the same computer before the improvement, then what would be the new execution time with the improvement?
