- 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).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).Make a comment on the following statement: "Traditional systems usually employ flat-file structures."
- 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.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).iii. load_data() takes three strings (filenames) as parameters. These files must have formats similar to movies.csv, ratings.csv, and tags.csv, in this order. Your function must read records from each of these files (except the data in their header rows) and store them in three separate 2-D lists. Let's call these lists movie_db, ratings_db, and tags_db, respectively. Your function must return these lists. If a file cannot be opened, it must print an error message and returns an empty list for that file. Make sure to convert all numeric data to their correct types (e.g., ints or floats) before you store them in a list. The sample output below shows how data should be stored in the returned lists. Since these are 2-D lists, we can use the display_list() function to print their elements as follows. >>> movies_db, ratings_db, tags_db = load_data("movies_20.csv", "ratings_20.csv", "tags_20.csv") >>> display_list(movies_db [2:5]) [3, 'Grumpier Old Men (1995)', 'Comedy | Romance'] [4,…
- Hi, in C programming , I try to implement 2 functions to check those followings instructions in a file text : The first function :Find the number of words with duplicates on a file The second function: • Find the most frequent letter (without considering duplicates) Finally write those results on another file. Thanks2. For reading and for processing data of employee records stored in a file named employee.txt,the contents of it need to be reversed from end to beginning. Write a C program to read a file in serial way, and reverse the contents of the employee record and then, again traverse and read the record in the newly reversed file.File system implementation: a. Given a filename in a directory’s data block, how does OS locate the data block of a file? b. Compare between direct pointers and indirect pointers in referencing data blocks. c. Given a 6GB file, identify the number of index level needed when using indirect pointer.
- 5. Assume a file system is using combined indexing scheme to keep track of the blocks allocated to a file, as in Linux/Unix file system. In the inode of a file, there are 12 direct pointers, one single-indirect pointer, one double-indirect pointer, and one triple-indirect pointer. Assume the size of a disk block address (i.e., disk pointer size) is 8 bytes. Assume block size is 4 KB. a) What is the maximum file size? b) How many index blocks are required for files of size 30 KB, 256KB, 15 MB, 512 MB, 32 GB? c) Assume nothing is cached (no disk caching applied in the system) and we know the disk location of the inode of a file of size 1 GB. How many disk accesses are required to access a byte at offset 2^14 (16K) in the file? How many disk accesses are required to access a byte at offset 2^26 in the file?The three most important file structure approaches should be described.Instructions to follow: Write all steps in detail wherever needed.
