Solved in 2 steps
- Can you explain what a file is? Why is it necessary to "open" and "close" a file? Suppose we do it that way, what will happen?2. Peter likes singing songs and playing music with an electric piano. (a) Peter uses an electric piano to play and record some music in a file. He then plays the file back with the sound of violin. (i) What is the file format? (ii) Other than file size, give an advantage of using the file format in (a)(i).Please solve the following in Java Sean can't remember where he put an important file on his computer. He desperately needs the file tonight to finish his homework, since he procrastinated all day by playing computer games. Unfortunately, his computer has gotten fried from all the gaming, and can no longer perform automatic searches for files. He therefore has to look for the file manually.Since he tends not to use subdirectories too much,he knows his best bet is to look for the file first in the root directory ("/"), and next in directories only one level deep (for example, "/Games/"), and so forth, checking the "deepest" directories last. His computer still has enough fire power to run some simple programs, so he has asked you to code for him a simple algorithm to sort all of the directories on his computer. ThealgorithmshouldtakeaString[]dirsasaninputand should sort dirs first by directory depth, and then lexicographically for each depth. So "/d/e/" comes before "/a/b/c/", but not…
- python processes--- Using Pool() do the following: 3.1. The pool must have 2 processes, each process will pass two parameters to a search function, these parameters must be the name of the file and a word to search for, these two parameters must be entered by the user and must be different from the process to another. 3.2. The Search function must search for the word in the file and if the word is found then find out the number of occurrences for this word otherwise return that the word doesn't appear in the file. 3.3. You need to verify that the file the user inserted is actually a file and it exists in the system.Description : The Goal: To encode text file by using the huffman code and after encode text file decode text file to the Original Text file, Output Encoded text file and Decode text file Requirements: Read Text file from user Frequency Table for Characters Encode Text file by using Huffman code [As teached in Section] . Encode Table (Each Character code from Huffman Code) Decode the Text File From user3. 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
- Is it true or false? The read position advances forwards, towards the end of the file, as things are read from it.Q1: Write a M-file program to enter a square matrix A(m,m), find: 1. The average of upper triangle. 2. The average of lower triangle. 3. The average of main diagonal. Q2: Write an M-file program to enter a square matrix A(m,m) and find the average of all element in the matrix except main diagonal? Q3: Write an M-file program to find the average of any matrix (A)?1 Encryption (a). Write a program that will utilise AES for encrypting and decrypting the data from a file as follows. Your program should take 3 arguments from the command line as input. The first input should be either 0 or 1 referring to encryption or decryption, respectively. The second input is the key filename. The third input is the either the plaintext or encrypted filename. If the first argument is 0: your program will read an AES key from a file titled key.txt (passed as second argument) and then will read the plaintext from a file titled plain- text.txt (passed as third argument), encrypt the contents of plaintext.txt using the key and save the ciphertext in a file titled encrypted.txt. If the first argument is 1, your program should decrypt the contents of encrypted.txt. Sample Command-line Inputs: java 0 key.txt plaintext.txt java 1 key.txt encrypted.txt
- 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…2. [summary_report.py] Timesheet data is easy to represent in a file, where it can be used to generate a report and help the worker get paid! Given an example set of data where each row represents a day of the week and each entry on the row represents a block of time worked, like this: 1.5h 3.25h 3.8h 6.Oh 1.eh 5. 5h 2.25h 0.75h 2.25h 3.0h 3.0h 5.75h 2.25h A report could be produced by a program like this: 0.00h | 5.25h | 1.5en 3.25h 0.5eh 10.00h 0.00h 3.00h 6.00h 1.00h 8.50h 5.50h 2.25h 8.75h 8.25h 8.00h 0.00h | e.00h 2.25h 3.00h 3.00h 5.75h 2.25h Weekly Total: 40.00h Notice how in the output file all the numbers are nicely formatted as right-aligned. Hint: you will probably need to use splitting, string slicing, converting data types, and string formatting. create a program that uses a data file that you have created, parses the data in that file to create a calculation per row and a running total, then writes the report to an output file. Your program should prompt a user to input a…Computer Science Design and implement an experiment to test the performance of read and write functions. Write a function called "copyfile" that will copy one file to another using read/write functions. Your function should take three parameters: source file, destination file and the number of bytes to copy at time. The function should return the time taken to copy the file. Run this experiment using different number of bytes to copy(1, 3, 5, 7, ....) and record the time for each experiment. Plot the graph (time, number of byte).
