A state is safe, if : a. the system does not crash due to deadlock occurrence b. the system can allocate resources to each process in some order and still avoid a deadlock c. the state keeps the system protected and safe d. all of the mentionedParallel:- Implement the parallel utility that has 3 command line arguments. This will execute 4 copies of the sleep process for 10 seconds. Your program should allow an arbitrary number of command line arguments for the process to be run in parallel. The parent process should wait for all child processes to finish before exiting back to the shell. If the format of the command is not recognized (e.g. the first argument is not an integer), an error can be displayed. All your code should be contained in the parallel.c file, and the Makefile. ./parallel<processes><cmd><args> For example, if you type: ./parallel 4 sleep 10 OUTPUT: SUCCESS in running 4 parallel sleep tasksPython script that performs the following:1. Define a function print_squares(n) that takes in an integer input (n) and prints thesquares of numbers from 1 to n.2. Define a function print_cubes(n) that takes in an integer input (n) and prints the cubes ofnumbers from 1 to n.3. In a main() function, use the threading module to create two threads: one that executesprint_squares(10) and another that executes print_cubes(10) concurrently.4. Now, in the same main() function, use the multiprocessing module to create twoprocesses: one that executes print_squares(10) and another that executesprint_cubes(10) in parallel.5. The main() function must only run automatically if the module is being run directly, notwhen imported.
- Title This assignment requires you to develop two Python programs. One is a client, the other is the... Description This assignment requires you to develop two Python programs. One is a client, the other is the server.</o:p> Server</o:p> The server should “register” x procedures that the client will be able to call. It will then bind to the address “localhost” and port 8000. This is the address and port that the server will listen to for requests. Note that if you have binding errors, you may use another port as your computer may have an application that is using 8000. Most of the time, however, this will work. Your server invocation must be in the following form:</o:p> python server.py localhost 8000These procedures to be supported are as follows:</o:p> name – returns the name of the server which is passed on the commandline during server invocation</o:p> help – returns a list of procedures that the server supports</o:p> servertime –…Course: Operating Systems write a multi-threadeddirectory copy program. The program will create destination directory and open thesource directory. Then for each file in the source directory it will create a thread. Thethread will copy file from source directory to the destination directory. At the end it willprint the number of files copied. Both the source and destination names will be passed ascommand line arguments. Sample execution is as follows:mtcopy.exe source_dir destination_dirCopied 8 files Note: The answer is availible on chegg.QUESTION 8: Practical (a) Cold Code Provide Java source code for the following problem. You can assume that all relevant packages have been imported. Provide a class called PrintMessage that is a task that can be run on a Thread. The constructor of PrintMessage sets the message to be displayed and repeat value, a number that represents the number of times the message must be displayed. When PrintMessage is started it prints the message to System.out then waits 200ms, this process is repeated based on the repeat value. Provide a Main class that instantiates a PrintMessage with appropriate values, loads the instance onto a Thread and starts it.

- Functions that are called by threads must have a property known as thread safety. T OR FDesign a program in Python programming language which has the following points. Take input from user a file name with location which is present in client system. Copy the file to the server system with same format. The file can be at any format ( .txt, .jpg, .mp3 etc ). The file received status should be printed on server and sent to client. Use socket programming to perform the task. Paste the code and output snapshot. Server Output: Waiting… Client Output: Enter file name and location to send : d:\r.jpg Sending…. Server Output: Waiting… Receiving… Client Output: Enter file name and location to send : d:\r.jpg Sending…. File Sent to Server. Server Output: Waiting… Receiving… File Received from Client.1.
