Draw the secondary disk storage for both files using index allocation.Show the content of the individual bytes allocated in memory in hexadecimal for the following declarations. Assuming that the address of I is 404000h, what are the addresses of J, K, and L? What is the total number of allocated bytes?One method that can be used to compress text data is run length encoding (RLE). When RLE is used the compressed data can be represented as a set of character/frequency pairs. When the same character appears in consecutive locations in the original text it is replaced in the compressed text by a single instance of the character followed by a number indicating the number of consecutive instances of that character. Single instances of a character are represented by the character followed by the number 1. Figure 9 and Figure 10 show examples of how text would be compressed using this method.

- There are many parameters that could be used to describe disk performance; among them are: number of bits per track disk capacity (in bits) number of disk surfaces rotational speed rotational latency transfer rate tracks per surface sectors per track blocks per track sectors per block seek time speed of disk arm block-read time number of blocks Some of these parameters are independent, and others are (approximately) linearly related. That is, doubling one doubles the other. Decide which of these parameters are linearly related. Then, select from the list below, the relationship that is true, to within a close approximation. Note: none of the statements may be true exactly, but one will always be much closer to the truth than the other three. Also note: you should assume all dimensions and parameters of the disk are unchanged except for the ones mentioned. a) If you double the number of sectors per block, then you double the number of blocks on the disk. b)…There are many parameters that could be used to describe disk performance; among them are: number of bits per track disk capacity (in bits) number of disk surfaces rotational speed rotational latency transfer rate tracks per surface sectors per track blocks per track sectors per block seek time speed of disk arm block-read time number of blocks Some of these parameters are independent, and others are (approximately) linearly related.

- Consider a file system that uses inodes to represent files. Disk blocks are 8 KB in size, and a pointer to a disk block requires 8 bytes. This file system has 12 direct disk blocks, as well as 1 single and 1 double indirect disk blocks. What is the maximum size of a file that can be stored in this file system in GBs (round to the nearest integer)?3. Implement a 32-bit subtraction of two numbers X and Y that are stored in memory as: X = (DS: 503H) MS byte of MS word (DS: 0502H) (DS: 0501H) (DS: 0500H) LS byte of MS byte of LS byte of MS word LS word LS word Y = (DS:0507H) (DS: 0506H) (DS: 0505H) (DS: 0504H) The result of X - Y is to be saved in the place where X is stored in memory.. The classical Tower of Hanoi (ToH) puzzle is well-known. It consists of three pegs and disks of sizes 1,2, . . . , n arranged on one of the pegs as a “tower”, in decreasing order of size, from bottom to top. The goal of the puzzle is to transfer all disks to another peg, placed in the same order. At each step, a single disk is moved from (the top of) one peg to (the top of) another, subject to the “divine” rule: to never have a larger disk above a smaller one.
- In MATLAB, a grey-scale image is stored a a matrix of numbers, all between 0 (black) and 255 (white). Since there are 256 possible values, 8 bits are needed or each pixel, in contrast to a normal integer, which is 64 bits.To save memory, grey-scale images are stored with a special data type, uint8 (unsigned 8-bit integer). In computer terminology, 8 bits = 1 byte. Even at one byte per pixel, a large image can consume a lot of memory. For example, a 1000x1000-pixel image takes 1 million bytes (which is a little less than 1 megabyte, since by convention 1 Mbyte = 2^20 bytes). One technique for reducing the size of an image is quantization - reducing the number of allowable levels from 256 to something smaller. Surprisingly, most images can be quantized by a large factor without losing much information. In this problem, you will quantize a grey-scale image to only 4 levels, so that it could (in principle) be stored as 2 bits per pixel. The template will read in an image file.
