- Does caching disk write operations have any advantages or disadvantages?CPU with interrupt-driven I/O is busy servicing a disk request. While the CPU is midway through the disk service routine, another I/O interrupt occurs. Q.) Is it a problem?A CPU with interrupt-driven I/O is busy servicing a disk request. While the CPU is midway through the disk-service routine, another I/O interrupt occurs.Q.) what can be done about it?

- For a 100-cylinder disk, compute the total number of head movements for the request queue provided below, using FCFS scheduling and a 100-cylinder disk (0-99). It is expected that the read write head is present at cylinder number 50 at the start of the program. Request queue for disk cylinders has the following numbers: 75, 25, 30, 68, 40, 89, 10.True/false: 1. One of the I/O module functions is command decoding 2. With multiple zoned recording, the amount of data that can be stored on the outer long track is the same as that can be stored on the inner short tracks, 3. Using Winchester head mechanism, the head is in a physical contact with the disk surface when it is in motion. 4. Scanning information at the same rate by rotating the disk at a fixed speed is known as the constant angular velocity. 5. The disadvantage of the software poll is that it is time consuming 6. When large volumes of data are to be moved, the most efficient technique is direct memory access (DMA). 7. In semiconductor memory, soft errors are permanent. 8. File organization on disk has no effect on I/O performance. 9. DRAMs are more densę than SRAMs 10 The areas between pits are called landsYou have a disk with an average seek time of 3ms. Its rotation speed is 20,000rpm. The disk is organized as 512-byte sectors with 500 sectors per track. Assume that the disk uses sequential organization. How long would it take to read a file consisting of 3000 sectors? What is the total size of the file read in MB?
