Since the access is sequential, greater the distance, greater will be the access time. Since all the files are referenced with equal frequency, overall access time can be reduced by arranging them as then ascending order of record as in option (a).

Explanation:

To optimize access time, we need to consider the concept of locality of reference. Locality of reference states that if a particular memory location is accessed, it is likely that nearby memory locations will also be accessed in the near future.

In this case, as all files are accessed with the same frequency, we need to consider the file sizes to determine the optimal order of storage. The idea is to minimize the number of disk accesses required to access all the files.

Step 1: Sort the files based on their sizes in descending order:

- F2 (200 records)
- F6 (150 records)
- F1 (100 records)
- F5 (120 records)
- F4 (80 records)
- F3 (50 records)

Step 2: Arrange the files in the order of their sizes:

- F2 (200 records)
- F6 (150 records)
- F5 (120 records)
- F1 (100 records)
- F4 (80 records)
- F3 (50 records)

Step 3: Determine the optimal order:

The optimal order is the one that minimizes the number of disk accesses required. In this case, we can use the First In First Out (FIFO) algorithm to determine the order.

- F3 (50 records)
- F4 (80 records)
- F1 (100 records)
- F5 (120 records)
- F6 (150 records)
- F2 (200 records)

Step 4: Final order:

The final order of storage that optimizes access time is: F3, F4, F1, F5, F6, F2 (as mentioned in option A).

Conclusion:

By arranging the files based on their sizes and using the FIFO algorithm, we can determine the optimal order of storage to minimize disk accesses and optimize access time.

Similar Computer Science Engineering (CSE) Doubts

An instruction pipeline has five stages, namely, instruction fetch (IF), instruction decode and register fetch (ID/RF), instruction execution (EX), memory access (MEM), and register writeback (WB) with stage latencies 1 ns, 2.2 ns, 2 ns, 1 ns, and 0.75 ns, respectively (ns stands for nanoseconds). To gain in terms of frequency, the designers have decided to split theID/RF stage into three stages (ID, RF1, RF2) each of latency 2.2/3 ns. Also, the EX stage is split into two stages (EX1, EX2) each of latency 1 ns. The new design has a total of eight pipeline stages. A program has 20% branch instructions which execute in the EX stage and produce the next instruction pointer at the end of the EX stage in the old design and at the end of the EX2 stage in the new design. The IF stage stalls after fetching a branch instruction until the next instruction pointer is computed. All instructions other than the branch instruction have an average CPI of one in both the designs. The execution times of this program on the old and the new design are P and Q nanoseconds, respectively. The value of P/Q is __________. Correct answer is '1.54'. Can you explain this answer?
