A disk drive has 1000 cylinders, 8 tracks per cylinder, 32 sectors per track, and 512 bytes per sector. The rotation time is 4ms. The read/write head takes 10ms to move between adjacent cylinders. A data file contains 200KB of data stored consecutively. What is the maximum seek time if the average time needed to read the data is 170ms?

You 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?
A disk has a capacity of two tera-byte size. Say the file system uses a multi-level inode structure for locating the data blocks of afile.The inode stores pointers to data blocks, including a single indirect block, a double indirect block, and several direct blocks in the 64 B of available space.Now, it is given that the disk has a block size of 512 B. The maximum file size that can be stored in such a file system in MB (round off upto 2 decimal places).
Consider a disk pack with 32 surfaces, 64 tracks and 512 sectors per pack. 256 bytes of data are stored in a bit serial manner in a sector. The number of bits required to specify a particular sector in the disk is.
Operating systems take great pains to ensure that a file's succeeding blocks are written to a media block in sequential order. As we often interact with magnetic disks, why is it imperative that we do so?
Suppose you have a 100GB database housed on a disk array that supports a transfer rate of 60MBps and a tape drive that supports 200GB cartridges with a transfer rate of 80MBps. How long will it take to back up the database? What is the transfer time if 2:1 compression is possible?
On a 16 GB hard disk drive (HDD), each cluster consists of 32 sectors and each sector has a fixed size of 512 bytes. A text file with a size of 150,000 bytes is to be stored. a. i.What is the size of the slack space, in bytes, once the file has been stored?
Suppose that a disk drive rotates at 8000 RPM. It has an average seek time of 4 milliseconds. If its transfer rate is 15 Mbps, determine the average time it takes for a 15K byte request to be transferred from the time the disk starts the seek? From this, determine its throughput.
Suppose a Unix Inode has 10 direct disk block pointers, one single indirect block pointer, one double indirect block pointer, and one triple indirect block pointer. For convenience, each index table has 256 = 28 entries and each block has 1K = 210 bytes. What is the maximum size of a Unix file in Kbytes?
Transfer rate of a disk drive can be no faster than the bit density (bits/track) times the rotational speed of the disk. Figure 7.15 gives a data transfer rate of 112GB/sec. Assume that the average track length of the disk is 5.5 inches. What is the average bit density of the disk?
If AES-192-CBC is used for encrypting a file of size 1800 byte, then find the total number of blocks that are generated by the whole process?
Cypher block chaining or cypher feedback mode is required if you need to deliver a large file.The question is, how much more productive is one?
TRUE or FALSE? A kilobyte of storage is 210 = 1,024 bytes, where a byte is a collection of 8 bits
