- 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.Write an algorithm and draw the flow chart for moving all the disks from Peg A to Peg B.A certain picture is constructed of a matrix of dots of color which have been created by mixing 3 primary colors of ink, where each ink color can have one of 320 different amounts (i.e. different intensities). If the picture has 106 x 106 dots of color, then what is the minimum number of Bytes (in kB to one decimal place) it would take to store a digitized image of this picture?Question 3: On a byte addressable machine a string COMSATS UNIVERSITY ISLAMABAD PAKISTAN, starting from logical address 0 (zero) to 36 is to be loaded into memory, in noncontiguous fashion, using 'Paging' technique. The string is divided mechanically into equal sized pages of 4 bytes; similarly the memory is also divided into equal sized frames of 4 bytes. The ASCII code of each Character occupies one byte. The free frame list is given as follows: 8,3,4,2,6,7 ,5,1,9,21,24, 11 Answer the following questions a. What is the page map table? b. What are the linear logical addresses of characters 'U' and_'B'? c. What are the linear physical addresses of characters 'U' and_'B'? d. What is the difference between Internal and External fragmentation? e. What is the internal fragmentation in loading given string?
- A video frame displayed onscreen consists of many pixels, with eachpixel, or cell, representing one unit of video output. A videodisplay’s resolution is typically specified in horizontal and verticalpixels (such as 1920 3 1080), and the number of pixels onscreen issimply the product of these numbers (1920 3 1080 5 2,073,600 pixels).A pixel’s data content is one or more unsigned integers. For ablack-and-white display, each pixel is a single number (usuallybetween 0 and 255) representing the intensity of the color white.Color pixel data is typically represented as one or three unsignedintegers.When three numbers are used, the numbers are usually between 0 and255, and each number represents the inten- sity of a primary color(red, green, or blue). When a single number is used, it represents apredefined color selected from a table (palette) of colors.Motion video is displayed onscreen by copying frames rapidly to thevideo display controller. Because video images or frames require manybytes…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. Figure 9 Original text: AAARRRRGGGHH Compressed text: A 3 R 4 G 3 H 2 Figure 10 Original text: CUTLASSES Compressed text: C 1 U 1 T 1 L 1 A 1 S 2 E 1 S 1 What you need to do Task 1 Write a Python program that will perform the compression process described above. The program should display a suitable prompt asking the user to input the text to compress and then output the compressed text. Task 2 Test…Suppose a program segment consists of a purely sequential part which takes 100 cycles to execute, and an iterated loop which takes 400 cycles per iteration. Assume that the loop is dependent on the sequential part, i.e., both parts cannot run in parallel. Also assume that the loop iterations are independent, and cannot be further parallelized. If the loop is to be executed 100 times, what is the maximum speedup possible using an infinite number of processors (as many processors as you could possibly need) compared to a single processor?
- Transcribed Image Text (Micro processer 8086) Q1) Choose the correct answer: 1. One of the following instructions is correct: a. MUL 67 b. LEA BL.[SI] (2. AS) c. LALF d. Neither a,b nor c 2. Suppose we have SS starts at B4102 H, CS ends at E4250H. The suitable point for DS to start so there are no overlapping of the segments is: c. C4200 H d. C4300 H a. C4000 H b. C4100 H 3. If you have AX-0208H, BL=D8H, the results of performing IDIV BL in AX is: a. 00F3 H b. F300 H c. 5802 H d. 0258 H 4. The Execution Unit includes: a. Instruction pointer b. Status register c. Address generation d. Neither a,b nor c 5. The compare instruction and test instruction are similar in : a. Both instructions are subtraction methods b. Both instructions effect on ZF, SF & PF. c. Both instructions store the result in the destination operand d. Neithe a,b nor c 6.

Then 20 P operations and 15 V operations were completed on this semaphore. The resulting value of the semaphore is:2. If we ignore the audio data in a video file, a video file is just a collection of many individual frames (i.e., images). What is the main reason that a video file can achieve a much higher compression ratio than a file that contains a single image file?
