implementation of Caesar Cipher Using Python Write Code: You are required to implement the Caesar Cipher encryption/decryption algorithm in Python. Remember to implement the algorithm in such a way that it takes a file as input, encrypts it and store in the current directory. This encrypted file must checkable. The implementation must have a decryption procedure which takes the encrypted file from the current directory, decrypts it and store it with some specific name in the current directory. The name should be different from the original file so that it can be verified.
Goal:Experimenting with AES-128 symmetric key cipher. Note:Using Python programming language that provided libraries for AES. Description:PART 1: write a program that uses AES-128 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and the outcome of the decryption, respectively.- To test this program, here's an example of an encrypted message (ciphertext.dat) and its 128-bit secret key (key.dat). PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have the first 96-bits of the 128-bit secret key (last 4 bytes of the secret key are missing!) The program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respectively. The program should print out on standard output the missing 4 bytes of the key in…
3. I/O Management: Disk Arm Scheduling & RAIDa. It is known that a disk drive has 256 cylinders, with cylinder numbers starting from 0 and ending at 255. The position of the needle on the disk drive currently stops at 128. It is also known that the needle always “goes to the cylinder with the smaller number first”. The order of the positions visited sequentially is: 254, 64, 32, 100, 50, 70. From the 3 choices of algorithms below, which one is the best algorithm? Make each image and determine the seektime.i. SCANii. C-SCANiii. FIFO
Please design the mapper and reducer for the below WordCount problem. WordCount problem: Given an input text file, count the frequency of each word in the file. Please design the input and output pairs for the Mapper and Reducer, use below table for reference. Input Output We get the "WordCount.jar" file by using the above table. It only contains Mapper and Reducer. There is no Combiner and no Partitioner in this program. Please illustrate how the WordCount.jar program works on the below dataset. This text file only contains one line. Dataset: the sound sounds sound. it is the right right, right? Suppose we run the WordCount.jar program on this file. Suppose that the space symbol, and "?" are all used for separating the words. The outputs of the Mapper are Mapper The outputs of the reducer are Reducer Answer: Are the results sorted alphabetically? When was it sorted? 2 27 20 35

Student information is being held in a data area, where each student record has the following format: The first nine bytes are the student number, held in ASCII The next byte is the course mark The next word is the section identifier There are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the records. If a2 has the address of a student record, if using indexed addressing mode, what is the index value X such that X(a2) addresses the course mark?
Operating system The free space bitmap looks like this:1010 0000 0000 0000:The system always searches for free blocks starting at the lowest numbered block. Block size is 4 KiB. (Blocks that belong to the same le do not need to be contiguous.) Write down the bitmap after each of the following actions:(a) File A of size 22 KiB is written.(b) File B of size 10 KiB is written.(c) File A is deleted.(d) File C of size 29 KiB is written.(e) File B is deleted.

Given the following declarations, write an assembly program segment that prompts the user to enter a 6-character secret word and an encryption key (a digit from I to 9). Then encrypt the secret word entered by adding the encryption key value to each of the character in the secret word and show the result of the encryption.
- An application loads 500 libraries at startup. Loading each library requires exactly one disk access. The seek time of the disk to a random location is given as 10ms. Rotational speed of disk is 6000rpm. If all 500 libraries are loaded from random locations on the disk, how long does it take to load all libraries?
Problem 0. Suppose a file contains 100 bytes of data. A program successfully opens it for both reading and writing (i.e., passing the mode O_READWR to open()), and gets back a file descriptor number fd. a. The program, which has a 40-byte buffer, issues a call to read() for 40 bytes. It processes that data, and then repeats the call. Both calls return the exact amount requested. Then it issues a third read, again requesting 40 bytes. What value will it return? (Assume no other program has the file open.) b. Next the program calls write (fd, buffer, 40), and the call returns 40. Then it issues another read() call for 40 bytes. What value does that call return? c. Suppose the programmer needs to read back the 40 bytes just written. First it must use 1seek() to reposition the file pointer. What parameters should it invoke 1seek () with so that the next read call will return the 40 bytes just written?
